Nicolaus Copernicus (/, -/;Polish: Mikołaj Kopernik; German: Nikolaus Kopernikus; Niklas Koppernigk; 19 February 1473 - 24 May 1543) was a Renaissance- and Reformation-era mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe, likely independently of Aristarchus of Samos, who had formulated such a model some eighteen centuries earlier.[a]
The publication of Copernicus' model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making an important contribution to the Scientific Revolution.
Copernicus was born and died in Royal Prussia, a region that had been part of the Kingdom of Poland since 1466. A polyglot and polymath, he obtained a doctorate in canon law and was also a mathematician, astronomer, physician, classics scholar, translator, governor, diplomat, and economist. In 1517 he derived a quantity theory of money - a key concept in economics - and in 1519 he formulated an economics principle that later came to be called Gresham's law.

Nicolaus Copernicus was born on 19 February 1473 in the city of Thorn (modern Toruń), in the province of Royal Prussia, in the Crown of the Kingdom of Poland. His father was a merchant from Kraków and his mother was the daughter of a wealthy Toruń merchant. Nicolaus was the youngest of four children. His brother Andreas (Andrew) became an Augustinian canon at Frombork (Frauenburg). His sister Barbara, named after her mother, became a Benedictine nun and, in her final years, prioress of a convent in Chełmno (Kulm); she died after 1517. His sister Katharina married the businessman and Toruń city councilor Barthel Gertner and left five children, whom Copernicus looked after to the end of his life. Copernicus never married and is not known to have had children, but from at least 1531 until 1539 his relations with Anna Schilling, a live-in housekeeper, were seen as scandalous by two bishops of Warmia who urged him over the years to break off relations with his "mistress".
Copernicus' father's family can be traced to a village in Silesia near Nysa (Neiße). The village's name has been variously spelled Kopernik, Copernik, Copernic, Kopernic, Coprirnik, and today Koperniki. In the 14th century, members of the family began moving to various other Silesian cities, to the Polish capital, Kraków (1367), and to Toruń (1400). The father, Mikołaj the Elder, likely the son of Jan, came from the Kraków line.
Nicolaus was named after his father, who appears in records for the first time as a well-to-do merchant who dealt in copper, selling it mostly in Danzig (Gdańsk). He moved from Kraków to Toruń around 1458. Toruń, situated on the Vistula River, was at that time embroiled in the Thirteen Years' War, in which the Kingdom of Poland and the Prussian Confederation, an alliance of Prussian cities, gentry and clergy, fought the Teutonic Order over control of the region. In this war, Hanseatic cities like Danzig and Toruń, Nicolaus Copernicus's hometown, chose to support the Polish King, Casimir IV Jagiellon, who promised to respect the cities' traditional vast independence, which the Teutonic Order had challenged. Nicolaus' father was actively engaged in the politics of the day and supported Poland and the cities against the Teutonic Order. In 1454 he mediated negotiations between Poland's Cardinal Zbigniew Oleśnicki and the Prussian cities for repayment of war loans. In the Second Peace of Thorn (1466), the Teutonic Order formally relinquished all claims to its western province, which as Royal Prussia remained a region of the Crown of the Kingdom of Poland until the First (1772) and Second (1793) Partitions of Poland.
Nicolaus' mother, Barbara Watzenrode, was the daughter of a wealthy Toruń patrician and city councillor, Lucas Watzenrode the Elder (deceased 1462), and Katarzyna (widow of Jan Peckau), mentioned in other sources as Katarzyna Rüdiger gente Modlibóg (deceased 1476). The Modlibógs were a prominent Polish family who had been well known in Poland's history since 1271. The Watzenrode family, like the Kopernik family, had come from Silesia from near Świdnica (Schweidnitz), and after 1360 had settled in Toruń. They soon became one of the wealthiest and most influential patrician families. Through the Watzenrodes' extensive family relationships by marriage, Copernicus was related to wealthy families of Toruń (Thorn), Gdańsk (Danzig) and Elbląg (Elbing), and to prominent Polish noble families of Prussia: the Czapskis, Działyńskis, Konopackis and Kościeleckis. Lucas and Katherine had three children: Lucas Watzenrode the Younger (1447-1512), who would become Bishop of Warmia and Copernicus's patron; Barbara, the astronomer's mother (deceased after 1495); and Christina (deceased before 1502), who in 1459 married the Toruń merchant and mayor, Tiedeman von Allen.
Lucas Watzenrode the Elder, a wealthy merchant and in 1439-62 president of the judicial bench, was a decided opponent of the Teutonic Knights. In 1453 he was the delegate from Toruń at the Grudziądz (Graudenz) conference that planned the uprising against them. During the ensuing Thirteen Years' War (1454-66), he actively supported the Prussian cities' war effort with substantial monetary subsidies (only part of which he later re-claimed), with political activity in Toruń and Danzig, and by personally fighting in battles at Łasin (Lessen) and Malbork (Marienburg). He died in 1462.
Lucas Watzenrode the Younger, the astronomer's maternal uncle and patron, was educated at the University of Kraków (now Jagiellonian University) and at the universities of Cologne and Bologna. He was a bitter opponent of the Teutonic Order, and its Grand Master once referred to him as "the devil incarnate". In 1489 Watzenrode was elected Bishop of Warmia (Ermeland, Ermland) against the preference of King Casimir IV, who had hoped to install his own son in that seat. As a result, Watzenrode quarreled with the king until Casimir IV's death three years later. Watzenrode was then able to form close relations with three successive Polish monarchs: John I Albert, Alexander Jagiellon, and Sigismund I the Old. He was a friend and key advisor to each ruler, and his influence greatly strengthened the ties between Warmia and Poland proper. Watzenrode came to be considered the most powerful man in Warmia, and his wealth, connections and influence allowed him to secure Copernicus' education and career as a canon at Frombork Cathedral.
Copernicus is postulated to have spoken Latin and German with equal fluency. He also spoke Polish,Greek and Italian.[b] The vast majority of Copernicus's surviving works are in Latin, which in his lifetime was the language of academia in Europe. Latin was also the official language of the Roman Catholic Church and of Poland's royal court, and thus all of Copernicus's correspondence with the Church and with Polish leaders was in Latin.
There survive a few documents written by Copernicus in German. The German philosophy professor Martin Carrier mentions this as a reason to consider Copernicus's native language to have been German. Other arguments for German being Copernicus's native tongue are that he was born in a predominantly German-speaking city and that, while studying canon law at Bologna in 1496, he signed into the German natio (Natio Germanorum) - a student organization which, according to its 1497 by-laws, was open to students of all kingdoms and states whose mother-tongue was German. However, according to French philosopher Alexandre Koyré, Copernicus's registration with the Natio Germanorum does not in itself imply that Copernicus considered himself German, since students from Prussia and Silesia were routinely so categorized, which carried certain privileges that made it a natural choice for German-speaking students, regardless of their ethnicity or self-identification.
The surname Copernik, Koppernigk is recorded in Kraków from c. 1350, in various spellings, apparently given to people from the village of Köppernigk (prior to 1845 rendered Koppirnik or Copirnik, Copernik) in the Silesian Duchy of Nysa. The Nuremberg Chronicle, published in 1493, describes of the town of Nysa population as plebs rustica polonici ydeomatis ... ("the vernacular language of the rural population is Polish"). Nicolas Copernicus' great-grandfather is recorded as having received citizenship in Kraków in 1386. The toponym Köppernig (modern Koperniki) has variously been tied to the German word for copper (Kupfer) and the Polish word for dill (koper). The suffix -nik (or plural -niki) denotes a Slavic and Polish agent noun.
As was common in the period, the spellings of both the toponym and the surname vary greatly. Copernicus "was rather indifferent about orthography". During his childhood, about 1480, the name of his father (and thus of the future astronomer) was recorded in Thorn as Niclas Koppernigk. At Kraków he signed himself, in Latin, Nicolaus Nicolai de Torunia (Nicolaus, son of Nicolaus, of Toruń). At Bologna, in 1496, he registered in the Matricula Nobilissimi Germanorum Collegii, resp. Annales Clarissimae Nacionis Germanorum, of the Natio Germanica Bononiae, as Dominus Nicolaus Kopperlingk de Thorn - IX grosseti. At Padua he signed himself "Nicolaus Copernik", later "Coppernicus". The astronomer thus Latinized his name to Coppernicus, generally with two "p"s (in 23 of 31 documents studied), but later in life he used a single "p". On the title page of De revolutionibus, Rheticus published the name (in the genitive, or possessive, case) as "Nicolai Copernici".[c]
Upon his father's death, young Nicolaus' maternal uncle, Lucas Watzenrode the Younger (1447-1512), took the boy under his wing and saw to his education and career. Watzenrode maintained contacts with leading intellectual figures in Poland and was a friend of the influential Italian-born humanist and Kraków courtier, Filippo Buonaccorsi. There are no surviving primary documents on the early years of Copernicus's childhood and education. Copernicus biographers assume that Watzenrode first sent young Copernicus to St. John's School, at Toruń, where he himself had been a master. Later, according to Armitage,[d] the boy attended the Cathedral School at Włocławek, up the Vistula River from Toruń, which prepared pupils for entrance to the University of Kraków, Watzenrode's alma mater in Poland's capital.
In the winter semester of 1491-92 Copernicus, as "Nicolaus Nicolai de Thuronia", matriculated together with his brother Andrew at the University of Kraków (now Jagiellonian University). Copernicus began his studies in the Department of Arts (from the fall of 1491, presumably until the summer or fall of 1495) in the heyday of the Kraków astronomical-mathematical school, acquiring the foundations for his subsequent mathematical achievements. According to a later but credible tradition (Jan Brożek), Copernicus was a pupil of Albert Brudzewski, who by then (from 1491) was a professor of Aristotelian philosophy but taught astronomy privately outside the university; Copernicus became familiar with Brudzewski's widely read commentary to Georg von Peuerbach's Theoricæ novæ planetarum and almost certainly attended the lectures of Bernard of Biskupie and Wojciech Krypa of Szamotuły, and probably other astronomical lectures by Jan of Głogów, Michał of Wrocław (Breslau), Wojciech of Pniewy, and Marcin Bylica of Olkusz.
Copernicus' Kraków studies gave him a thorough grounding in the mathematical astronomy taught at the University (arithmetic, geometry, geometric optics, cosmography, theoretical and computational astronomy) and a good knowledge of the philosophical and natural-science writings of Aristotle (De coelo, Metaphysics) and Averroes (which in the future would play an important role in the shaping of Copernicus' theory), stimulating his interest in learning and making him conversant with humanistic culture. Copernicus broadened the knowledge that he took from the university lecture halls with independent reading of books that he acquired during his Kraków years (Euclid, Haly Abenragel, the Alfonsine Tables, Johannes Regiomontanus' Tabulae directionum); to this period, probably, also date his earliest scientific notes, now preserved partly at Uppsala University. At Kraków Copernicus began collecting a large library on astronomy; it would later be carried off as war booty by the Swedes during the Deluge in the 1650s and is now at the Uppsala University Library.
Copernicus' four years at Kraków played an important role in the development of his critical faculties and initiated his analysis of logical contradictions in the two "official" systems of astronomy - Aristotle's theory of homocentric spheres, and Ptolemy's mechanism of eccentrics and epicycles - the surmounting and discarding of which would be the first step toward the creation of Copernicus' own doctrine of the structure of the universe.
Without taking a degree, probably in the fall of 1495, Copernicus left Kraków for the court of his uncle Watzenrode, who in 1489 had been elevated to Prince-Bishop of Warmia and soon (before November 1495) sought to place his nephew in the Warmia canonry vacated by the 26 August 1495 death of its previous tenant, Jan Czanow. For unclear reasons - probably due to opposition from part of the chapter, who appealed to Rome - Copernicus' installation was delayed, inclining Watzenrode to send both his nephews to study canon law in Italy, seemingly with a view to furthering their ecclesiastic careers and thereby also strengthening his own influence in the Warmia chapter.
Leaving Warmia in mid-1496 - possibly with the retinue of the chapter's chancellor, Jerzy Pranghe, who was going to Italy - in the fall, possibly in October, Copernicus arrived in Bologna and a few months later (after 6 January 1497) signed himself into the register of the Bologna University of Jurists' "German nation", which included young Poles from Silesia, Prussia and Pomerania as well as students of other nationalities.
It was only on 20 October 1497 that Copernicus, by proxy, formally succeeded to the Warmia canonry which had been granted to him two years earlier. To this, by a document dated 10 January 1503 at Padua, he would add a sinecure at the Collegiate Church of the Holy Cross in Wrocław, Silesia, Bohemia. Despite having been granted a papal indult on 29 November 1508 to receive further benefices, through his ecclesiastic career Copernicus not only did not acquire further prebends and higher stations (prelacies) at the chapter, but in 1538 he relinquished the Wrocław sinecure. It is unclear whether he was ever ordained a priest.Edward Rosen asserts that he was not. Copernicus did take minor orders, which sufficed for assuming a chapter canonry.The Catholic Encyclopedia proposes that his ordination was probable, as in 1537 he was one of four candidates for the episcopal seat of Warmia, a position which required ordination.
During his three-year stay at Bologna, between fall 1496 and spring 1501, Copernicus seems to have devoted himself less keenly to studying canon law (he received his doctorate in law only after seven years, following a second return to Italy in 1503) than to studying the humanities - probably attending lectures by Filippo Beroaldo, Antonio Urceo, called Codro, Giovanni Garzoni, and Alessandro Achillini - and to studying astronomy. He met the famous astronomer Domenico Maria Novara da Ferrara and became his disciple and assistant. Copernicus was developing new ideas inspired by reading the "Epitome of the Almagest" (Epitome in Almagestum Ptolemei) by George von Peuerbach and Johannes Regiomontanus (Venice, 1496). He verified its observations about certain peculiarities in Ptolemy's theory of the Moon's motion, by conducting on 9 March 1497 at Bologna a memorable observation of the occultation of Aldebaran, the brightest star in the Taurus constellation, by the moon. Copernicus the humanist sought confirmation for his growing doubts through close reading of Greek and Latin authors (Pythagoras, Aristarchos of Samos, Cleomedes, Cicero, Pliny the Elder, Plutarch, Philolaus, Heraclides, Ecphantos, Plato), gathering, especially while at Padua, fragmentary historic information about ancient astronomical, cosmological and calendar systems.
Copernicus spent the jubilee year 1500 in Rome, where he arrived with his brother Andrew that spring, doubtless to perform an apprenticeship at the Papal Curia. Here, too, however, he continued his astronomical work begun at Bologna, observing, for example, a lunar eclipse on the night of 5-6 November 1500. According to a later account by Rheticus, Copernicus also - probably privately, rather than at the Roman Sapienza - as a "Professor Mathematum" (professor of astronomy) delivered, "to numerous... students and... leading masters of the science", public lectures devoted probably to a critique of the mathematical solutions of contemporary astronomy.
On his return journey doubtless stopping briefly at Bologna, in mid-1501 Copernicus arrived back in Warmia. After on 28 July receiving from the chapter a two-year extension of leave in order to study medicine (since "he may in future be a useful medical advisor to our Reverend Superior [Bishop Lucas Watzenrode] and the gentlemen of the chapter"), in late summer or in the fall he returned again to Italy, probably accompanied by his brother Andrew and by Canon Bernhard Sculteti. This time he studied at the University of Padua, famous as a seat of medical learning, and - except for a brief visit to Ferrara in May-June 1503 to pass examinations for, and receive, his doctorate in canon law - he remained at Padua from fall 1501 to summer 1503.
Copernicus studied medicine probably under the direction of leading Padua professors - Bartolomeo da Montagnana, Girolamo Fracastoro, Gabriele Zerbi, Alessandro Benedetti - and read medical treatises that he acquired at this time, by Valescus de Taranta, Jan Mesue, Hugo Senensis, Jan Ketham, Arnold de Villa Nova, and Michele Savonarola, which would form the embryo of his later medical library.
One of the subjects that Copernicus must have studied was astrology, since it was considered an important part of a medical education. However, unlike most other prominent Renaissance astronomers, he appears never to have practiced or expressed any interest in astrology.
As at Bologna, Copernicus did not limit himself to his official studies. It was probably the Padua years that saw the beginning of his Hellenistic interests. He familiarized himself with Greek language and culture with the aid of Theodorus Gaza's grammar (1495) and J.B. Chrestonius' dictionary (1499), expanding his studies of antiquity, begun at Bologna, to the writings of Basilius Bessarion, Lorenzo Valla and others. There also seems to be evidence that it was during his Padua stay that the idea finally crystallized, of basing a new system of the world on the movement of the Earth. As the time approached for Copernicus to return home, in spring 1503 he journeyed to Ferrara where, on 31 May 1503, having passed the obligatory examinations, he was granted the degree of doctor of canon law (Nicolaus Copernich de Prusia, Jure Canonico ... et doctoratus). No doubt it was soon after (at latest, in fall 1503) that he left Italy for good to return to Warmia.
Copernicus made three observations of Mercury, with errors of -3, -15 and -1 minutes of arc. He made one of Venus, with an error of -24 minutes. Four were made of Mars, with errors of 2, 20, 77, and 137 minutes. Four observations were made of Jupiter, with errors of 32, 51, -11 and 25 minutes. He made four of Saturn, with errors of 31, 20, 23 and -4 minutes.
Having completed all his studies in Italy, 30-year-old Copernicus returned to Warmia, where he would live out the remaining 40 years of his life, apart from brief journeys to Kraków and to nearby Prussian cities: Toruń (Thorn), Gdańsk (Danzig), Elbląg (Elbing), Grudziądz (Graudenz), Malbork (Marienburg), Königsberg (Królewiec).
Copernicus was his uncle's secretary and physician from 1503 to 1510 (or perhaps till his uncle's death on 29 March 1512) and resided in the Bishop's castle at Lidzbark (Heilsberg), where he began work on his heliocentric theory. In his official capacity, he took part in nearly all his uncle's political, ecclesiastic and administrative-economic duties. From the beginning of 1504, Copernicus accompanied Watzenrode to sessions of the Royal Prussian diet held at Malbork and Elbląg and, write Dobrzycki and Hajdukiewicz, "participated... in all the more important events in the complex diplomatic game that ambitious politician and statesman played in defense of the particular interests of Prussia and Warmia, between hostility to the [Teutonic] Order and loyalty to the Polish Crown."
In 1504-12 Copernicus made numerous journeys as part of his uncle's retinue - in 1504, to Toruń and Gdańsk, to a session of the Royal Prussian Council in the presence of Poland's King Alexander Jagiellon; to sessions of the Prussian diet at Malbork (1506), Elbląg (1507) and Sztum (Stuhm) (1512); and he may have attended a Poznań (Posen) session (1510) and the coronation of Poland's King Sigismund I the Old in Kraków (1507). Watzenrode's itinerary suggests that in spring 1509 Copernicus may have attended the Kraków sejm.
It was probably on the latter occasion, in Kraków, that Copernicus submitted for printing at Jan Haller's press his translation, from Greek to Latin, of a collection, by the 7th-century Byzantine historian Theophylact Simocatta, of 85 brief poems called Epistles, or letters, supposed to have passed between various characters in a Greek story. They are of three kinds - "moral," offering advice on how people should live; "pastoral", giving little pictures of shepherd life; and "amorous", comprising love poems. They are arranged to follow one another in a regular rotation of subjects. Copernicus had translated the Greek verses into Latin prose, and he now published his version as Theophilacti scolastici Simocati epistolae morales, rurales et amatoriae interpretatione latina, which he dedicated to his uncle in gratitude for all the benefits he had received from him. With this translation, Copernicus declared himself on the side of the humanists in the struggle over the question whether Greek literature should be revived. Copernicus's first poetic work was a Greek epigram, composed probably during a visit to Kraków, for Johannes Dantiscus' epithalamium for Barbara Zapolya's 1512 wedding to King Zygmunt I the Old.
Some time before 1514, Copernicus wrote an initial outline of his heliocentric theory known only from later transcripts, by the title (perhaps given to it by a copyist), Nicolai Copernici de hypothesibus motuum coelestium a se constitutis commentariolus - commonly referred to as the Commentariolus. It was a succinct theoretical description of the world's heliocentric mechanism, without mathematical apparatus, and differed in some important details of geometric construction from De revolutionibus; but it was already based on the same assumptions regarding Earth's triple motions. The Commentariolus, which Copernicus consciously saw as merely a first sketch for his planned book, was not intended for printed distribution. He made only a very few manuscript copies available to his closest acquaintances, including, it seems, several Kraków astronomers with whom he collaborated in 1515-30 in observing eclipses. Tycho Brahe would include a fragment from the Commentariolus in his own treatise, Astronomiae instauratae progymnasmata, published in Prague in 1602, based on a manuscript that he had received from the Bohemian physician and astronomer Tadeáš Hájek, a friend of Rheticus. The Commentariolus would appear complete in print for the first time only in 1878.
In 1510 or 1512 Copernicus moved to Frombork, a town to the northwest at the Vistula Lagoon on the Baltic Sea coast. There, in April 1512, he participated in the election of Fabian of Lossainen as Prince-Bishop of Warmia. It was only in early June 1512 that the chapter gave Copernicus an "external curia" - a house outside the defensive walls of the cathedral mount. In 1514 he purchased the northwestern tower within the walls of the Frombork stronghold. He would maintain both these residences to the end of his life, despite the devastation of the chapter's buildings by a raid against Frauenburg carried out by the Teutonic Order in January 1520, during which Copernicus's astronomical instruments were probably destroyed. Copernicus conducted astronomical observations in 1513-16 presumably from his external curia; and in 1522-43, from an unidentified "small tower" (turricula), using primitive instruments modeled on ancient ones - the quadrant, triquetrum, armillary sphere. At Frombork Copernicus conducted over half of his more than 60 registered astronomical observations.
Having settled permanently at Frombork, where he would reside to the end of his life, with interruptions in 1516-19 and 1520-21, Copernicus found himself at the Warmia chapter's economic and administrative center, which was also one of Warmia's two chief centers of political life. In the difficult, politically complex situation of Warmia, threatened externally by the Teutonic Order's aggressions (attacks by Teutonic bands; the Polish-Teutonic War of 1519-21; Albert's plans to annex Warmia), internally subject to strong separatist pressures (the selection of the prince-bishops of Warmia; currency reform), he, together with part of the chapter, represented a program of strict cooperation with the Polish Crown and demonstrated in all his public activities (the defense of his country against the Order's plans of conquest; proposals to unify its monetary system with the Polish Crown's; support for Poland's interests in the Warmia dominion's ecclesiastic administration) that he was consciously a citizen of the Polish-Lithuanian Republic. Soon after the death of uncle Bishop Watzenrode, he participated in the signing of the Second Treaty of Piotrków Trybunalski (7 December 1512), governing the appointment of the Bishop of Warmia, declaring, despite opposition from part of the chapter, for loyal cooperation with the Polish Crown.
That same year (before 8 November 1512) Copernicus assumed responsibility, as magister pistoriae, for administering the chapter's economic enterprises (he would hold this office again in 1530), having already since 1511 fulfilled the duties of chancellor and visitor of the chapter's estates.
His administrative and economic dutes did not distract Copernicus, in 1512-15, from intensive observational activity. The results of his observations of Mars and Saturn in this period, and especially a series of four observations of the Sun made in 1515, led to discovery of the variability of Earth's eccentricity and of the movement of the solar apogee in relation to the fixed stars, which in 1515-19 prompted his first revisions of certain assumptions of his system. Some of the observations that he made in this period may have had a connection with a proposed reform of the Julian calendar made in the first half of 1513 at the request of the Bishop of Fossombrone, Paul of Middelburg. Their contacts in this matter in the period of the Fifth Lateran Council were later memorialized in a complimentary mention in Copernicus's dedicatory epistle in Dē revolutionibus orbium coelestium and in a treatise by Paul of Middelburg, Secundum compendium correctionis Calendarii (1516), which mentions Copernicus among the learned men who had sent the Council proposals for the calendar's emendation.
During 1516-21, Copernicus resided at Olsztyn (Allenstein) Castle as economic administrator of Warmia, including Olsztyn (Allenstein) and Pieniężno (Mehlsack). While there, he wrote a manuscript, Locationes mansorum desertorum (Locations of Deserted Fiefs), with a view to populating those fiefs with industrious farmers and so bolstering the economy of Warmia. When Olsztyn was besieged by the Teutonic Knights during the Polish-Teutonic War, Copernicus directed the defense of Olsztyn and Warmia by Royal Polish forces. He also represented the Polish side in the ensuing peace negotiations.
Copernicus for years advised the Royal Prussian sejmik on monetary reform, particularly in the 1520s when that was a major question in regional Prussian politics. In 1526 he wrote a study on the value of money, Monetae cudendae ratio. In it he formulated an early iteration of the theory, now called Gresham's law, that "bad" (debased) coinage drives "good" (un-debased) coinage out of circulation - several decades before Thomas Gresham. He also, in 1517, set down a quantity theory of money, a principal concept in economics to the present day. Copernicus's recommendations on monetary reform were widely read by leaders of both Prussia and Poland in their attempts to stabilize currency.
In 1533, Johann Widmanstetter, secretary to Pope Clement VII, explained Copernicus's heliocentric system to the Pope and two cardinals. The Pope was so pleased that he gave Widmanstetter a valuable gift. In 1535 Bernard Wapowski wrote a letter to a gentleman in Vienna, urging him to publish an enclosed almanac, which he claimed had been written by Copernicus. This is the only mention of a Copernicus almanac in the historical records. The "almanac" was likely Copernicus's tables of planetary positions. Wapowski's letter mentions Copernicus's theory about the motions of the earth. Nothing came of Wapowski's request, because he died a couple of weeks later.
Following the death of Prince-Bishop of Warmia Mauritius Ferber (1 July 1537), Copernicus participated in the election of his successor, Johannes Dantiscus (20 September 1537). Copernicus was one of four candidates for the post, written in at the initiative of Tiedemann Giese; but his candidacy was actually pro forma, since Dantiscus had earlier been named coadjutor bishop to Ferber and since Dantiscus had the backing of Poland's King Sigismund I. At first Copernicus maintained friendly relations with the new Prince-Bishop, assisting him medically in spring 1538 and accompanying him that summer on an inspection tour of Chapter holdings. But that autumn, their friendship was strained by suspicions over Copernicus's housekeeper, Anna Schilling, whom Dantiscus banished from Frombork in spring 1539.
In his younger days, Copernicus the physician had treated his uncle, brother and other chapter members. In later years he was called upon to attend the elderly bishops who in turn occupied the see of Warmia - Mauritius Ferber and Johannes Dantiscus - and, in 1539, his old friend Tiedemann Giese, Bishop of Chełmno (Kulm). In treating such important patients, he sometimes sought consultations from other physicians, including the physician to Duke Albert and, by letter, the Polish Royal Physician.
In the spring of 1541, Duke Albert - former Grand Master of the Teutonic Order who had converted the Monastic State of the Teutonic Knights into a Lutheran and hereditary realm, the Duchy of Prussia, upon doing homage to his uncle, the King of Poland, Sigismund I - summoned Copernicus to Königsberg to attend the Duke's counselor, George von Kunheim, who had fallen seriously ill, and for whom the Prussian doctors seemed unable to do anything. Copernicus went willingly; he had met von Kunheim during negotiations over reform of the coinage. And Copernicus had come to feel that Albert himself was not such a bad person; the two had many intellectual interests in common. The Chapter readily gave Copernicus permission to go, as it wished to remain on good terms with the Duke, despite his Lutheran faith. In about a month the patient recovered, and Copernicus returned to Frombork. For a time, he continued to receive reports on von Kunheim's condition, and to send him medical advice by letter.
Some of Copernicus's close friends turned Protestant, but Copernicus never showed a tendency in that direction. The first attacks on him came from Protestants. Wilhelm Gnapheus, a Dutch refugee settled in Elbląg, wrote a comedy in Latin, Morosophus (The Foolish Sage), and staged it at the Latin school that he had established there. In the play, Copernicus was caricatured as a haughty, cold, aloof man who dabbled in astrology, considered himself inspired by God, and was rumored to have written a large work that was moldering in a chest.
Elsewhere Protestants were the first to react to news of Copernicus's theory. Melanchthon wrote:
Some people believe that it is excellent and correct to work out a thing as absurd as did that Sarmatian [i.e., Polish] astronomer who moves the earth and stops the sun. Indeed, wise rulers should have curbed such light-mindedness.
Nevertheless, in 1551, eight years after Copernicus's death, astronomer Erasmus Reinhold published, under the sponsorship of Copernicus's former military adversary, the Protestant Duke Albert, the Prussian Tables, a set of astronomical tables based on Copernicus's work. Astronomers and astrologers quickly adopted it in place of its predecessors.
Some time before 1514 Copernicus made available to friends his "Commentariolus" ("Little Commentary"), a forty-page manuscript describing his ideas about the heliocentric hypothesis.[e] It contained seven basic assumptions (detailed below). Thereafter he continued gathering data for a more detailed work.
About 1532 Copernicus had basically completed his work on the manuscript of Dē revolutionibus orbium coelestium; but despite urging by his closest friends, he resisted openly publishing his views, not wishing - as he confessed - to risk the scorn "to which he would expose himself on account of the novelty and incomprehensibility of his theses."
In 1533, Johann Albrecht Widmannstetter delivered a series of lectures in Rome outlining Copernicus's theory. Pope Clement VII and several Catholic cardinals heard the lectures and were interested in the theory. On 1 November 1536, Cardinal Nikolaus von Schönberg, Archbishop of Capua, wrote to Copernicus from Rome:
Some years ago word reached me concerning your proficiency, of which everybody constantly spoke. At that time I began to have a very high regard for you... For I had learned that you had not merely mastered the discoveries of the ancient astronomers uncommonly well but had also formulated a new cosmology. In it you maintain that the earth moves; that the sun occupies the lowest, and thus the central, place in the universe... Therefore with the utmost earnestness I entreat you, most learned sir, unless I inconvenience you, to communicate this discovery of yours to scholars, and at the earliest possible moment to send me your writings on the sphere of the universe together with the tables and whatever else you have that is relevant to this subject ...
By then Copernicus's work was nearing its definitive form, and rumors about his theory had reached educated people all over Europe. Despite urgings from many quarters, Copernicus delayed publication of his book, perhaps from fear of criticism - a fear delicately expressed in the subsequent dedication of his masterpiece to Pope Paul III. Scholars disagree on whether Copernicus's concern was limited to possible astronomical and philosophical objections, or whether he was also concerned about religious objections.[f]
Copernicus was still working on De revolutionibus orbium coelestium (even if not certain that he wanted to publish it) when in 1539 Georg Joachim Rheticus, a Wittenberg mathematician, arrived in Frombork. Philipp Melanchthon, a close theological ally of Martin Luther, had arranged for Rheticus to visit several astronomers and study with them. Rheticus became Copernicus's pupil, staying with him for two years and writing a book, Narratio prima (First Account), outlining the essence of Copernicus's theory. In 1542 Rheticus published a treatise on trigonometry by Copernicus (later included as chapters 13 and 14 of Book I of De revolutionibus). Under strong pressure from Rheticus, and having seen the favorable first general reception of his work, Copernicus finally agreed to give De revolutionibus to his close friend, Tiedemann Giese, bishop of Chełmno (Kulm), to be delivered to Rheticus for printing by the German printer Johannes Petreius at Nuremberg (Nürnberg), Germany. While Rheticus initially supervised the printing, he had to leave Nuremberg before it was completed, and he handed over the task of supervising the rest of the printing to a Lutheran theologian, Andreas Osiander.
Osiander added an unauthorised and unsigned preface, defending Copernicus' work against those who might be offended by its novel hypotheses. He argued that "different hypotheses are sometimes offered for one and the same motion [and therefore] the astronomer will take as his first choice that hypothesis which is the easiest to grasp." According to Osiander, "these hypotheses need not be true nor even probable. [I]f they provide a calculus consistent with the observations, that alone is enough."
Toward the close of 1542, Copernicus was seized with apoplexy and paralysis, and he died at age 70 on 24 May 1543. Legend has it that he was presented with the final printed pages of his Dē revolutionibus orbium coelestium on the very day that he died, allowing him to take farewell of his life's work. He is reputed to have awoken from a stroke-induced coma, looked at his book, and then died peacefully.
Copernicus was reportedly buried in Frombork Cathedral, where archaeologists for over two centuries searched in vain for his remains. Efforts to locate the remains in 1802, 1909, 1939 and 2004 had come to nought. In August 2005, however, a team led by Jerzy Gąssowski, head of an archaeology and anthropology institute in Pułtusk, after scanning beneath the cathedral floor, discovered what they believed to be Copernicus's remains.
The find came after a year of searching, and the discovery was announced only after further research, on 3 November 2008. Gąssowski said he was "almost 100 percent sure it is Copernicus".Forensic expert Capt. Dariusz Zajdel of the Polish Police Central Forensic Laboratory used the skull to reconstruct a face that closely resembled the features - including a broken nose and a scar above the left eye - on a Copernicus self-portrait. The expert also determined that the skull belonged to a man who had died around age 70 - Copernicus's age at the time of his death.
The grave was in poor condition, and not all the remains of the skeleton were found; missing, among other things, was the lower jaw. The DNA from the bones found in the grave matched hair samples taken from a book owned by Copernicus which was kept at the library of the University of Uppsala in Sweden.
On 22 May 2010 Copernicus was given a second funeral in a Mass led by Józef Kowalczyk, the former papal nuncio to Poland and newly named Primate of Poland. Copernicus's remains were reburied in the same spot in Frombork Cathedral where part of his skull and other bones had been found. A black granite tombstone now identifies him as the founder of the heliocentric theory and also a church canon. The tombstone bears a representation of Copernicus's model of the solar system - a golden sun encircled by six of the planets.
Philolaus (c. 480-385 BCE) described an astronomical system in which a Central Fire (different from the Sun) occupied the centre of the universe, and a counter-Earth, the Earth, Moon, the Sun itself, planets, and stars all revolved around it, in that order outward from the centre.Heraclides Ponticus (387-312 BCE) proposed that the Earth rotates on its axis.Aristarchus of Samos (ca. 310 BCE - ca. 230 BCE) was the first to advance a theory that the earth orbited the sun. Further mathematical details of Aristarchus' heliocentric system were worked out around 150 BCE by the Hellenistic astronomer Seleucus of Seleucia. Though Aristarchus' original text has been lost, a reference in Archimedes' book The Sand Reckoner (Archimedis Syracusani Arenarius & Dimensio Circuli) describes a work by Aristarchus in which he advanced the heliocentric model. Thomas Heath gives the following English translation of Archimedes' text:
You are now aware ['you' being King Gelon] that the "universe" is the name given by most astronomers to the sphere the centre of which is the centre of the earth, while its radius is equal to the straight line between the centre of the sun and the centre of the earth. This is the common account (τά γραφόμενα) as you have heard from astronomers. But Aristarchus has brought out a book consisting of certain hypotheses, wherein it appears, as a consequence of the assumptions made, that the universe is many times greater than the "universe" just mentioned. His hypotheses are that the fixed stars and the sun remain unmoved, that the earth revolves about the sun on the circumference of a circle, the sun lying in the middle of the orbit, and that the sphere of the fixed stars, situated about the same centre as the sun, is so great that the circle in which he supposes the earth to revolve bears such a proportion to the distance of the fixed stars as the centre of the sphere bears to its surface.
Copernicus cited Aristarchus of Samos in an early (unpublished) manuscript of De Revolutionibus (which still survives), though he removed the reference from his final published manuscript.
Copernicus was probably aware that Pythagoras's system involved a moving earth. The Pythagorean system was mentioned by Aristotle.
Copernicus owned a copy of Giorgio Valla's "De expetendis et fugiendis rebus", which included a translation of Plutarch's reference to Aristarchus's heliostaticism.
In Copernicus' dedication of On the Revolutions to Pope Paul III - which Copernicus hoped would dampen criticism of his heliocentric theory by "babblers... completely ignorant of [astronomy]" - the book's author wrote that, in rereading all of philosophy, in the pages of Cicero and Plutarch he had found references to those few thinkers who dared to move the Earth "against the traditional opinion of astronomers and almost against common sense."
Some technical details of Copernicus's system[g] closely resembled those developed earlier by the Islamic astronomers Naṣīr al-Dīn al-Ṭūsī and Ibn al-Shāṭir, both of whom retained a geocentric model. Aryabhata (476-550), in his magnum opus Aryabhatiya (499), propounded a planetary model in which the Earth was taken to be spinning on its axis and the periods of the planets were given with respect to the Sun. He accurately calculated many astronomical constants, such as the periods of the planets, times of the solar and lunar eclipses, and the instantaneous motion of the Moon.
At the Maragha observatory, Najm al-Dīn al-Qazwīnī al-Kātibī (died 1277), in his Hikmat al-'Ain, wrote an argument for a heliocentric model, but later abandoned the model. Qutb al-Din Shirazi (born 1236) also discussed the possibility of heliocentrism, but rejected it. Ibn al-Shatir (born 1304) developed a geocentric system that employed mathematical techniques, such as the Tusi couple and Urdi lemma, that were almost identical to those Nicolaus Copernicus later employed in his heliocentric system, implying that its mathematical model was influenced by the Maragha school.
Nilakantha Somayaji (1444-1544), in his Aryabhatiyabhasya, a commentary on Aryabhata's Aryabhatiya, developed a computational system for a partially heliocentric planetary model, in which the planets orbit the Sun, which in turn orbits the Earth, similar to the Tychonic system later proposed by Tycho Brahe in the late 16th century. In the Tantrasangraha (1500), he further revised his planetary system, which was mathematically more accurate at predicting the heliocentric orbits of the interior planets than both the Tychonic and Copernican models.
The prevailing theory in Europe during Copernicus's lifetime was the one that Ptolemy published in his Almagest circa 150 CE; the Earth was the stationary center of the universe. Stars were embedded in a large outer sphere which rotated rapidly, approximately daily, while each of the planets, the Sun, and the Moon were embedded in their own, smaller spheres. Ptolemy's system employed devices, including epicycles, deferents and equants, to account for observations that the paths of these bodies differed from simple, circular orbits centered on the Earth.
Copernicus' major work on his heliocentric theory was Dē revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), published in the year of his death, 1543. He had formulated his theory by 1510. "He wrote out a short overview of his new heavenly arrangement [known as the Commentariolus, or Brief Sketch], also probably in 1510 [but no later than May 1514], and sent it off to at least one correspondent beyond Varmia [the Latin for "Warmia"]. That person in turn copied the document for further circulation, and presumably the new recipients did, too..."
Copernicus' Commentariolus summarized his heliocentric theory. It listed the "assumptions" upon which the theory was based, as follows:
1. There is no one center of all the celestial circles or spheres.7. The apparent retrograde and direct motion of the planets arises not from their motion but from the earth's. The motion of the earth alone, therefore, suffices to explain so many apparent inequalities in the heavens.
2. The center of the earth is not the center of the universe, but only of gravity and of the lunar sphere.
3. All the spheres revolve about the sun as their midpoint, and therefore the sun is the center of the universe.
4. The ratio of the earth's distance from the sun to the height of the firmament (outermost celestial sphere containing the stars) is so much smaller than the ratio of the earth's radius to its distance from the sun that the distance from the earth to the sun is imperceptible in comparison with the height of the firmament.
5. Whatever motion appears in the firmament arises not from any motion of the firmament, but from the earth's motion. The earth together with its circumjacent elements performs a complete rotation on its fixed poles in a daily motion, while the firmament and highest heaven abide unchanged.
6. What appear to us as motions of the sun arise not from its motion but from the motion of the earth and our sphere, with which we revolve about the sun like any other planet. The earth has, then, more than one motion.
De revolutionibus itself was divided into six sections or parts, called "books":
- General vision of the heliocentric theory, and a summarized exposition of his idea of the World
- Mainly theoretical, presents the principles of spherical astronomy and a list of stars (as a basis for the arguments developed in the subsequent books)
- Mainly dedicated to the apparent motions of the Sun and to related phenomena
- Description of the Moon and its orbital motions
- Exposition of the motions in longitude of the non-terrestrial planets
- Exposition of the motions in latitude of the non-terrestrial planets
Georg Joachim Rheticus could have been Copernicus's successor, but did not rise to the occasion.Erasmus Reinhold could have been his successor, but died prematurely. The first of the great successors was Tycho Brahe (though he did not think the earth orbited the sun), followed by Johannes Kepler, who had collaborated with Tycho in Prague and benefited from Tycho's decades' worth of detailed observational data.
Despite the near universal acceptance later of the heliocentric idea (though not the epicycles or the circular orbits), Copernicus's theory was originally slow to catch on. Scholars hold that sixty years after the publication of The Revolutions there were only around 15 astronomers espousing Copernicanism in all of Europe: "Thomas Digges and Thomas Harriot in England; Giordano Bruno and Galileo Galilei in Italy; Diego Zuniga in Spain; Simon Stevin in the Low Countries; and in Germany, the largest group - Georg Joachim Rheticus, Michael Maestlin, Christoph Rothmann (who may have later recanted), and Johannes Kepler." Additional possibilities are Englishman William Gilbert, along with Achilles Gasser, Georg Vogelin, Valentin Otto, and Tiedemann Giese.
Arthur Koestler, in his popular book The Sleepwalkers, asserted that Copernicus's book had not been widely read on its first publication. This claim was trenchantly criticised by Edward Rosen,[h] and has been decisively disproved by Owen Gingerich, who examined nearly every surviving copy of the first two editions and found copious marginal notes by their owners throughout many of them. Gingerich published his conclusions in 2004 in The Book Nobody Read.
The intellectual climate of the time "remained dominated by Aristotelian philosophy and the corresponding Ptolemaic astronomy. At that time there was no reason to accept the Copernican theory, except for its mathematical simplicity [by avoiding using the equant in determining planetary positions]." Tycho Brahe's system ("that the earth is stationary, the sun revolves about the earth, and the other planets revolve about the sun") also directly competed with Copernicus's. It was only a half century later with the work of Kepler and Galileo that any substantial evidence defending Copernicanism appeared, starting "from the time when Galileo formulated the principle of inertia...[which] helped to explain why everything would not fall off the earth if it were in motion." "[Not until] after Isaac Newton formulated the universal law of gravitation and the laws of mechanics [in his 1687 Principia], which unified terrestrial and celestial mechanics, was the heliocentric view generally accepted."
The immediate result of the 1543 publication of Copernicus's book was only mild controversy. At the Council of Trent (1545-63) neither Copernicus's theory nor calendar reform (which would later use tables deduced from Copernicus's calculations) were discussed. It has been much debated why it was not until six decades after the publication of De revolutionibus that the Catholic Church took any official action against it, even the efforts of Tolosani going unheeded. Catholic side opposition only commenced seventy-three years later, when it was occasioned by Galileo.
The first notable to move against Copernicanism was the Magister of the Holy Palace (i.e., the Catholic Church's chief censor), Dominican Bartolomeo Spina, who "expressed a desire to stamp out the Copernican doctrine". But with Spina's death in 1546, his cause fell to his friend, the well known theologian-astronomer, the Dominican Giovanni Maria Tolosani of the Convent of St. Mark in Florence. Tolosani had written a treatise on reforming the calendar (in which astronomy would play a large role) and had attended the Fifth Lateran Council (1512-17) to discuss the matter. He had obtained a copy of De Revolutionibus in 1544. His denunciation of Copernicanism was written a year later, in 1545, in an appendix to his unpublished work, On the Truth of Sacred Scripture.
Emulating the rationalistic style of Thomas Aquinas, Tolosani sought to refute Copernicanism by philosophical argument. Copernicanism was absurd, according to Tolosani, because it was scientifically unproven and unfounded. First, Copernicus had assumed the motion of the Earth but offered no physical theory whereby one would deduce this motion. (No one realized that the investigation into Copernicanism would result in a rethinking of the entire field of physics.) Second, Tolosani charged that Copernicus's thought process was backwards. He held that Copernicus had come up with his idea and then sought phenomena that would support it, rather than observing phenomena and deducing from them the idea of what caused them. In this, Tolosani was linking Copernicus's mathematical equations with the practices of the Pythagoreans (whom Aristotle had made arguments against, which were later picked up by Thomas Aquinas). It was argued that mathematical numbers were a mere product of the intellect without any physical reality, and as such could not provide physical causes in the investigation of nature.
Some astronomical hypotheses at the time (such as epicycles and eccentrics) were seen as mere mathematical devices to adjust calculations of where the heavenly bodies would appear, rather than an explanation of the cause of those motions. (As Copernicus still maintained the idea of perfectly spherical orbits, he relied on epicycles.) This "saving the phenomena" was seen as proof that astronomy and mathematics could not be taken as serious means to determine physical causes. Tolosani invoked this view in his final critique of Copernicus, saying that his biggest error was that he had started with "inferior" fields of science to make pronouncements about "superior" fields. Copernicus had used mathematics and astronomy to postulate about physics and cosmology, rather than beginning with the accepted principles of physics and cosmology to determine things about astronomy and mathematics. Thus Copernicus seemed to be undermining the whole system of the philosophy of science at the time. Tolosani held that Copernicus had fallen into philosophical error because he had not been versed in physics and logic; anyone without such knowledge would make a poor astronomer and be unable to distinguish truth from falsehood. Because Copernicanism had not met the criteria for scientific truth set out by Thomas Aquinas, Tolosani held that it could only be viewed as a wild unproven theory.
Tolosani recognized that the Ad Lectorem preface to Copernicus's book was not actually by him. Its thesis that astronomy as a whole would never be able to make truth claims was rejected by Tolosani (though he still held that Copernicus's attempt to describe physical reality had been faulty); he found it ridiculous that Ad Lectorem had been included in the book (unaware that Copernicus had not authorized its inclusion). Tolosani wrote: "By means of these words [of the Ad Lectorem], the foolishness of this book's author is rebuked. For by a foolish effort he [Copernicus] tried to revive the weak Pythagorean opinion [that the element of fire was at the center of the Universe], long ago deservedly destroyed, since it is expressly contrary to human reason and also opposes holy writ. From this situation, there could easily arise disagreements between Catholic expositors of holy scripture and those who might wish to adhere obstinately to this false opinion." Tolosani declared: "Nicolaus Copernicus neither read nor understood the arguments of Aristotle the philosopher and Ptolemy the astronomer." Tolosani wrote that Copernicus "is expert indeed in the sciences of mathematics and astronomy, but he is very deficient in the sciences of physics and logic. Moreover, it appears that he is unskilled with regard to [the interpretation of] holy scripture, since he contradicts several of its principles, not without danger of infidelity to himself and the readers of his book. ...his arguments have no force and can very easily be taken apart. For it is stupid to contradict an opinion accepted by everyone over a very long time for the strongest reasons, unless the impugner uses more powerful and insoluble demonstrations and completely dissolves the opposed reasons. But he does not do this in the least."
Tolosani declared that he had written against Copernicus "for the purpose of preserving the truth to the common advantage of the Holy Church." Despite this, his work remained unpublished and there is no evidence that it received serious consideration. Robert Westman describes it as becoming a "dormant" viewpoint with "no audience in the Catholic world" of the late sixteenth century, but also notes that there is some evidence that it did become known to Tommaso Caccini, who would criticize Galileo in a sermon in December 1613.
Tolosani may have criticized the Copernican theory as scientifically unproven and unfounded, but the theory also conflicted with the theology of the time, as can be seen in a sample of the works of John Calvin. In his Commentary on Genesis he said that "We indeed are not ignorant that the circuit of the heavens is finite, and that the earth, like a little globe, is placed in the centre." In his commentary on Psalms 93:1 he states that "The heavens revolve daily, and, immense as is their fabric and inconceivable the rapidity of their revolutions, we experience no concussion.... How could the earth hang suspended in the air were it not upheld by God's hand? By what means could it maintain itself unmoved, while the heavens above are in constant rapid motion, did not its Divine Maker fix and establish it." One sharp point of conflict between Copernicus's theory and the Bible concerned the story of the Battle of Gibeon in the Book of Joshua where the Hebrew forces were winning but whose opponents were likely to escape once night fell. This is averted by Joshua's prayers causing the sun and the moon to stand still. Martin Luther once made a remark about Copernicus, although without mentioning his name. According to Anthony Lauterbach, while eating with Martin Luther the topic of Copernicus arose during dinner on 4 June 1539 (in the same year as professor George Joachim Rheticus of the local University had been granted leave to visit him). Luther is said to have remarked "So it goes now. Whoever wants to be clever must agree with nothing others esteem. He must do something of his own. This is what that fellow does who wishes to turn the whole of astronomy upside down. Even in these things that are thrown into disorder I believe the Holy Scriptures, for Joshua commanded the sun to stand still and not the earth." These remarks were made four years before the publication of On the Revolutions of the Heavenly Spheres and a year before Rheticus' Narratio Prima. In John Aurifaber's account of the conversation Luther calls Copernicus "that fool" rather than "that fellow", this version is viewed by historians as less reliably sourced.
Luther's collaborator Philipp Melanchthon also took issue with Copernicanism. After receiving the first pages of Narratio Prima from Rheticus himself, Melanchthon wrote to Mithobius (physician and mathematician Burkard Mithob of Feldkirch) on 16 October 1541 condemning the theory and calling for it to be repressed by governmental force, writing "certain people believe it is a marvelous achievement to extol so crazy a thing, like that Polish astronomer who makes the earth move and the sun stand still. Really, wise governments ought to repress impudence of mind." It had appeared to Rheticus that Melanchton would understand the theory and would be open to it. This was because Melanchton had taught Ptolemaic astronomy and had even recommended his friend Rheticus to an appointment to the Deanship of the Faculty of Arts & Sciences at the University of Wittenberg after he had returned from studying with Copernicus.
Rheticus' hopes were dashed when six years after the publication of De Revolutionibus Melanchthon published his Initia Doctrinae Physicae presenting three grounds to reject Copernicanism. These were "the evidence of the senses, the thousand-year consensus of men of science, and the authority of the Bible". Blasting the new theory Melanchthon wrote "Out of love for novelty or in order to make a show of their cleverness, some people have argued that the earth moves. They maintain that neither the eighth sphere nor the sun moves, whereas they attribute motion to the other celestial spheres, and also place the earth among the heavenly bodies. Nor were these jokes invented recently. There is still extant Archimedes' book on The sand-reckoner; in which he reports that Aristarchus of Samos propounded the paradox that the sun stands still and the earth revolves around the sun. Even though subtle experts institute many investigations for the sake of exercising their ingenuity, nevertheless public proclamation of absurd opinions is indecent and sets a harmful example." Melanchthon went on to cite Bible passages and then declare "Encouraged by this divine evidence, let us cherish the truth and let us not permit ourselves to be alienated from it by the tricks of those who deem it an intellectual honor to introduce confusion into the arts." In the first edition of Initia Doctrinae Physicae, Melanchthon even questioned Copernicus's character claiming his motivation was "either from love of novelty or from desire to appear clever", these more personal attacks were largely removed by the second edition in 1550.
Another Protestant theologian who took issue with Copernicus was John Owen who declared that "the late hypothesis, fixing the sun as in the centre of the world' was 'built on fallible phenomena, and advanced by many arbitrary presumptions against evident testimonies of Scripture."
In Roman Catholic circles, German Jesuit Nicolaus Serarius was one of the first to write against Copernicus's theory as heretical, citing the Joshua passage, in a work published in 1609-1610, and again in a book in 1612. In his 12 April 1615 letter to a Catholic defender of Copernicus, Paolo Antonio Foscarini, Catholic Cardinal Robert Bellarmine condemned Copernican theory, writing "...not only the Holy Fathers, but also the modern commentaries on Genesis, the Psalms, Ecclesiastes, and Joshua, you will find all agreeing in the literal interpretation that the sun is in heaven and turns around the earth with great speed, and that the earth is very far from heaven and sits motionless at the center of the world...Nor can one answer that this is not a matter of faith, since if it is not a matter of faith 'as regards the topic,' it is a matter of faith 'as regards the speaker': and so it would be heretical to say that Abraham did not have two children and Jacob twelve, as well as to say that Christ was not born of a virgin, because both are said by the Holy Spirit through the mouth of prophets and apostles."
Perhaps the most influential opponent of the Copernican theory was Francesco Ingoli, a Catholic priest. Ingoli wrote a January 1616 essay to Galileo presenting more than twenty arguments against the Copernican theory. Though "it is not certain, it is probable that he [Ingoli] was commissioned by the Inquisition to write an expert opinion on the controversy", (after the Congregation of the Index's decree against Copernicanism on 5 March 1616, Ingoli was officially appointed its consultant). Galileo himself was of the opinion that the essay played an important role in the rejection of the theory by church authorities, writing in a later letter to Ingoli that he was concerned that people thought the theory was rejected because Ingoli was right. Ingoli presented five physical arguments against the theory, thirteen mathematical arguments (plus a separate discussion of the sizes of stars), and four theological arguments. The physical and mathematical arguments were of uneven quality, but many of them came directly from the writings of Tycho Brahe, and Ingoli repeatedly cited Brahe, the leading astronomer of the era. These included arguments about the effect of a moving earth on the trajectory of projectiles, and about parallax and Brahe's argument that the Copernican theory required that stars be absurdly large. Two of Ingoli's theological issues with the Copernican theory were "common Catholic beliefs not directly traceable to Scripture: the doctrine that hell is located at the center of Earth and is most distant from heaven; and the explicit assertion that Earth is motionless in a hymn sung on Tuesdays as part of the Liturgy of the Hours of the Divine Office prayers regularly recited by priests." Ingoli cited Robert Bellarmine in regards to both of these arguments, and may have been trying to convey to Galileo a sense of Bellarmine's opinion. Ingoli also cited Genesis 1:14 where God places "lights in the firmament of the heavens to divide the day from the night." Ingoli did not think the central location of the sun in the Copernican theory was compatible with it being described as one of the lights placed in the firmament. Like previous commentators Ingoli also pointed to the passages about the Battle of Gibeon. He dismissed arguments that they should be taken metaphorically, saying "Replies which assert that Scripture speaks according to our mode of understanding are not satisfactory: both because in explaining the Sacred Writings the rule is always to preserve the literal sense, when it is possible, as it is in this case; and also because all the [Church] Fathers unanimously take this passage to mean that the sun which was truly moving stopped at Joshua's request. An interpretation which is contrary to the unanimous consent of the Fathers is condemned by the Council of Trent, Session IV, in the decree on the edition and use of the Sacred Books. Furthermore, although the Council speaks about matters of faith and morals, nevertheless it cannot be denied that the Holy Fathers would be displeased with an interpretation of Sacred Scriptures which is contrary to their common agreement." However, Ingoli closed the essay by suggesting Galileo respond primarily to the better of his physical and mathematical arguments rather than to his theological arguments, writing "Let it be your choice to respond to this either entirely of in part - clearly at least to the mathematical and physical arguments, and not to all even of these, but to the more weighty ones." When Galileo wrote a letter in reply to Ingoli years later, he in fact only addressed the mathematical and physical arguments.
In March 1616, in connection with the Galileo affair, the Roman Catholic Church's Congregation of the Index issued a decree suspending De revolutionibus until it could be "corrected," on the grounds of ensuring that Copernicanism, which it described as a "false Pythagorean doctrine, altogether contrary to the Holy Scripture," would not "creep any further to the prejudice of Catholic truth." The corrections consisted largely of removing or altering wording that the spoke of heliocentrism as a fact, rather than a hypothesis. The corrections were made based largely on work by Ingoli.
On the orders of Pope Paul V, Cardinal Robert Bellarmine gave Galileo prior notice that the decree was about to be issued, and warned him that he could not "hold or defend" the Copernican doctrine.[i] The corrections to De revolutionibus, which omitted or altered nine sentences, were issued four years later, in 1620.
In 1633 Galileo Galilei was convicted of grave suspicion of heresy for "following the position of Copernicus, which is contrary to the true sense and authority of Holy Scripture", and was placed under house arrest for the rest of his life.
At the instance of Roger Boscovich, the Catholic Church's 1758 Index of Prohibited Books omitted the general prohibition of works defending heliocentrism, but retained the specific prohibitions of the original uncensored versions of De revolutionibus and Galileo's Dialogue Concerning the Two Chief World Systems. Those prohibitions were finally dropped from the 1835 Index.
There has been discussion of Copernicus' nationality and of whether it is meaningful to ascribe to him a nationality in the modern sense.
Nicolaus Copernicus was born and raised in Royal Prussia, a semiautonomous and polyglot region of the Kingdom of Poland. He was the child of German-speaking parents and grew up with German as his mother tongue. His first alma mater was the University of Kraków in Poland. When he later studied in Italy, at the University of Bologna, he joined the German Nation, a student organization for German-speakers of all allegiances (Germany would not become a nation-state until 1871). His family stood against the Teutonic Order and actively supported the city of Toruń during the Thirteen Years' War (1454-66). Copernicus' father lent money to Poland's King Casimir IV Jagiellon to finance the war against the Teutonic Knights, but the inhabitants of Royal Prussia also resisted the Polish crown's efforts for greater control over the region.
Encyclopædia Britannica,Encyclopedia Americana,The Concise Columbia Encyclopedia,The Oxford World Encyclopedia, and World Book Encyclopedia refer to Copernicus as a "Polish astronomer". Sheila Rabin, writing in the Stanford Encyclopedia of Philosophy, describes Copernicus as a "child of a German family [who] was a subject of the Polish crown", while Manfred Weissenbacher writes that Copernicus's father was a Germanized Pole.
There are additional arguments for Kopernik's Polish descent on his father's side. Kopernik's Y-DNA haplogroup, R1b L51, is found in southern Poland (in Silesia, where his father came from), but not in Germany or Austria. The surname Kopernik is typically Polish, with its suffix -nik, indicating an occupation (e.g. cukiernik, "confectioner", or górnik, "miner"); while Koper- may refer to koprowina, an old Polish term for the Latin "cuprum" ("copper"}. The surname Kopernik is now found in Poland in 130 persons, and in Germany in only 22, mostly Polish immigrants to Germany. No Polish texts by Copernicus survive due to the rarity of Polish literary language before the writings of the Polish Renaissance poets Mikołaj Rej and Jan Kochanowski (educated Poles had generally written in Latin); but it is known that Copernicus knew Polish on a par with German and Latin.
Historian Michael Burleigh describes the nationality debate as a "totally insignificant battle" between German and Polish scholars during the interwar period. Polish astronomer Konrad Rudnicki calls the discussion a "fierce scholarly quarrel in ... times of nationalism" and describes Copernicus as an inhabitant of a German-speaking territory that belonged to Poland, himself being of mixed Polish-German extraction.
Czesław Miłosz describes the debate as an "absurd" projection of a modern understanding of nationality onto Renaissance people, who identified with their home territories rather than with a nation. Similarly, historian Norman Davies writes that Copernicus, as was common in his era, was "largely indifferent" to nationality, being a local patriot who considered himself "Prussian". Miłosz and Davies both write that Copernicus had a German-language cultural background, while his working language was Latin in accord with the usage of the time. Additionally, according to Davies, "there is ample evidence that he knew the Polish language". Davies concludes that, "Taking everything into consideration, there is good reason to regard him both as a German and as a Pole: and yet, in the sense that modern nationalists understand it, he was neither."
On 14 July 2009, the discoverers, from the Gesellschaft für Schwerionenforschung in Darmstadt, Germany, of chemical element 112 (temporarily named ununbium) proposed to the International Union of Pure and Applied Chemistry (IUPAC) that its permanent name be "copernicium" (symbol Cn). "After we had named elements after our city and our state, we wanted to make a statement with a name that was known to everyone," said Hofmann. "We didn't want to select someone who was a German. We were looking world-wide." On the 537th anniversary of his birthday the official naming was released to the public.
55 Cancri A
In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars. The process involved public nomination and voting for the new names. In December 2015, the IAU announced the winning name for 55 Cancri A was Copernicus.
Contemporary literary and artistic works inspired by Copernicus
- Mover of the Earth, Stopper of the Sun for symphony orchestra (overture), written by composer Svitlana Azarova commissioned by ONDIF
- Doctor Copernicus, a 1975 novel by John Banville, sketches the life of Copernicus and the 16th-century world in which he lived.
- Linton 2004, pp. 39, 119. The Greek mathematician and astronomer Aristarchus of Samos proposed such a system during the third century BCE, but there is little evidence that his ideas were developed beyond a basic outline (Dreyer 1953, pp. 135-48)[dubious ]. Copernicus was aware of Aristarchus' heliocentric theory and cited him in an early (unpublished) manuscript of De Revolutionibus (which still survives), though he removed the reference from his final published manuscript.
- He used Latin and German, knew enough Greek to translate the 7th-century Byzantine poet Theophylact Simocatta's verses into Latin prose and "there is ample evidence that he knew the Polish language". During his several years' studies in Italy, Copernicus presumably would also have learned some Italian. Professor Stefan Melkowski of Nicolaus Copernicus University in Toruń likewise asserts that Copernicus spoke both German and Polish.
- See the title page at The book
- Dobrzycki and Hajdukiewicz (1969) describe Copernicus having attended school at Włocławek as unlikely.
- A reference to the "Commentariolus" is contained in a library catalogue, dated 1 May 1514, of a 16th-century historian, Matthew of Miechów, so it must have begun circulating before that date (Koyré, 1973, p. 85; Gingerich, 2004, p. 32). Thoren (1990 p. 99) gives the length of the manuscript as 40 pages.
- Koyré (1973, pp. 27, 90) and Rosen (1995, pp. 64,184) take the view that Copernicus was indeed concerned about possible objections from theologians, while Lindberg and Numbers (1986) argue against it. Koestler (1963) also denies it. Indirect evidence that Copernicus was concerned about objections from theologians comes from a letter written to him by Andreas Osiander in 1541, in which Osiander advises Copernicus to adopt a proposal by which he says "you will be able to appease the Peripatetics and theologians whose opposition you fear". (Koyré, 1973, pp. 35, 90)
- Particularly his use of the Tusi couple and his models for the motions of Mercury and the Moon (Linton 2004, pp. 124, 137-38)
- Rosen (1995, pp. 187-92), originally published in 1967 in Saggi su Galileo Galilei . Rosen is particularly scathing about this and other statements in The Sleepwalkers, which he criticizes as inaccurate.
- Fantoli (2005, pp. 118-19); Finocchiaro (1989, pp. 148, 153). On-line copies of Finocchiaro's translations of the relevant documents, Inquisition Minutes of 25 February 1616 and Cardinal Bellarmine's certificate of 26 May 1616, have been made available by Gagné (2005). This notice of the decree would not have prevented Galileo from discussing heliocentrism solely as a mathematical hypothesis, but a stronger formal injunction (Finocchiaro, 1989, p. 147-148) not to teach it "in any way whatever, either orally or in writing", allegedly issued to him by the Commissary of the Holy Office, Father Michelangelo Segizzi, would certainly have done so (Fantoli, 2005, pp. 119-20, 137). There has been much controversy over whether the copy of this injunction in the Vatican archives is authentic; if so, whether it was ever issued; and if so, whether it was legally valid (Fantoli, 2005, pp. 120-43).
- The oldest known portrait of Copernicus is that on Strasbourg astronomical clock, made by Tobias Stimmer c. 1571-4. According to the inscription next to the portrait, it was made from a self-portrait by Copernicus himself. This has led to speculation that the Torun portrait may be a copy based on the same self-portrait, but its provenance is unknown.

- Dava Sobel writes: "Copernicus had no idea that Aristarchus of Samos had proposed much the same thing [as Copernicus was contemplating by 1510, when he wrote his Brief Sketch, otherwise also known as the Commentariolus] in the third century B.C. The only work by Aristarchus known to Copernicus - a treatise called On the Sizes and Distances of the Sun and Moon - made no mention of a heliocentric plan." Sobel (2011) pp. 18-19. Sobel further writes that in Copernicus' dedication of On the Revolutions to Pope Paul III - which Copernicus hoped would dampen criticism of his heliocentric theory by "babblers... completely ignorant of [astronomy]" - the book's author wrote that, in rereading all of philosophy, in the pages of Cicero and Plutarch he had found references to those few thinkers who dared to move the Earth "against the traditional opinion of astronomers and almost against common sense." Sobel comments: "He still knew nothing of the Earth-moving plan of Aristarchus, which had not yet been reported to Latin audiences." (pp. 179-82).

- "Copernicus seems to have drawn up some notes [on the displacement of good coin from circulation by debased coin] while he was at Olsztyn in 1519. He made them the basis of a report on the matter, written in German, which he presented to the Prussian Diet held in 1522 at Grudziądz... He later drew up a revised and enlarged version of his little treatise, this time in Latin, and setting forth a general theory of money, for presentation to the Diet of 1528."

- "Although great importance has frequently been ascribed to this fact, it does not imply that Copernicus considered himself to be a German. The 'nationes' of a medieval university had nothing in common with nations in the modern sense of the word. Students who were natives of Prussia and Silesia were automatically described as belonging to the Natio Germanorum. Furthmore, at Bologna, this was the 'privileged' nation; consequently, Copernicus had very good reason for inscribing himself on its register." Koyre, p. 21
- "It is important to recognize, however, that the medieval Latin concept of natio, or "nation", referred to the community of feudal lords both in Germany and elsewhere, not to 'the people' in the nineteenth-century democratic or nationalistic sense of the word." Johnson, p. 23.

Mosko ("copper") and S.

Nikolao KOPERNIKO (naskiĝis la 19-an de februaro 1473; mortis la 24-an de majo 1543) (latine: Copernicus; pole: Mikołaj Kopernik [miˈkɔwaj kɔˈpɜrnik], germane: Nikolaus Koppernigk) - Renesanca astronomo, juristo, matematikisto, okupiĝis ankaŭ pri ekonomiko, militista strategio, astrologio, kuracado kaj tradukado.
Li verkis la libron De revolutionibus orbium coelestium, en kiu li tezis la suncentran teorion (heliocentrisma): la Tero kaj la planedoj iras ĉirkaŭ la Suno. La libro estis eldonita je lia morto en 1543; eble li ne eldonis ĝin dum sia vivo pro timo al la eklezio, kies altranguloj kredis je la sistemo de Ptolemeo, kiu metis la Teron en la centron, ne la Sunon. Aŭ eble li timis la mokadon de profesoroj, kiuj tiam ankaŭ kredis al Ptolemeo. Lia verko estis parte prezentita antaŭ papo Klemento la 7-a. Pro sia revolucia pensaro kaj disvastigemo li estas opiniita kiel granda eŭropa filozofo. Poste per la termino "kopernika revolucio" estis nomita la filozofio de Immanuel Kant.
Post lia morto, la eklezio traktis lian teorion kiel konvena matematika fikcio (laŭ la antaŭparolo de Osiandro), sed dum 1611-32 Galileo eltrovis la pruvon por la teorio en la ĉielo per teleskopo. Galileo fariĝis frua kaj forta evangeliisto de la sistemo de Koperniko, sed iuj el liaj pruvoj malpravis (precipe lia pruvo per tajdomovo). Lia evangeliado fine tiris la atenton kaj koleron de la eklezio sur lian kapon. En 1616, la eklezio malpermesis la libron de Koperniko (ĝis 1822), kaj en 1633 ĝi mutigis Galileon.
Koperniko estis naskita la 19an de februaro 1473 en la grandurbo Toruń (Dorno), en la provinco Reĝa Prusio, en la Krono de la Regno de Pollando. Lia patro estis komercisto de Krakovo kaj lia patrino estis la filino de riĉa Toruń-komercisto. Nikolao estis la plej juna de kvar infanoj. Lia frato Andreas (Andreo) iĝis aŭgustena kanoniko ĉe Frombork (Frauenburg). Lia fratino Barbara, nomita laŭ ŝia patrino, iĝis benediktana monaĥino kaj, en siaj lastjaraj klasoj, priorino de monaĥejo en Chełmno (Kulm); ŝi mortis post 1517. Lia fratino Katharina geedziĝis kun la komercisto kaj kun Toruń urbokonsilisto Barthel Gertner kaj forlasis kvin filojn, kiujn Koperniko zorgis poste je la fino de sia vivo. Koperniko neniam geedziĝis aŭ havis filojn.
La familio de la patro povas esti spurita al vilaĝo en Silezio proksime de Nysa (Neiße). La nomo de la vilaĝo estis diverse literumita Kopernik, Copernik, Copernic, Kopernic, Coprirnik, kaj hodiaŭ Koperniki. En la 14-a jarcento, membroj de la familio komencis moviĝi al diversaj aliaj sileziaj grandurboj, al la pola ĉefurbo, Krakovo (1367), kaj al Toruń (1400). La patro, Mikołaj la Maljuna, verŝajne la filo de Jan, venis de la Krakovo-linio.
Nikolao estis nomita laŭ sia patro, kiu aperas en arkivoj por la unua fojo kiel bonhava komercisto kiu komercis pri kupro, vendante ĝin plejparte en Danzig (Gdańsk). Li moviĝis de Krakovo al Toruń ĉirkaŭ 1458. Toruń, troviĝis ĉe la Vistulo, kaj estis en tiu tempo implikita en la Dektrijara Milito, en kiu la Regno de Pollando kaj la Prusa Konfederacio, nome alianco de prusaj grandurboj, subnobelaro kaj pastraro, kontraŭbatalis la Ĝermanan Ordon pri kontrolo de la regiono. En tiu milito, hanseataj grandurboj kiel Danzig kaj Toruń, la hejmurbo de Koperniko, elektis apogi la polan reĝon, Kazimiro la 4-a, kiu promesis respekti la tradician vastan sendependecon de la grandurboj, kiun la teŭtona ordo defiis. La patro de Nikolao estis aktive engaĝita pri la tiama politiko kaj apogis Pollandon kaj la grandurbojn kontraŭ la teŭtona ordo. En 1454 li mediaciis intertraktade inter kardinalo Zbigniew Oleśnicki de Pollando kaj la prusaj grandurboj por repago de militpruntoj En la Dua Paco de Toruń, la teŭtona ordo formale cedis ĉiujn postulojn al siaj okcidentaj provincoj, kiuj kiel Reĝa Prusio restis regiono de Pollando dum la venontaj 300 jaroj.
La patrino de Nikolao, nome Barbara Watzenrode, estis la filino de riĉa Toruń patricia kaj urba delegito, Lucas Watzenrode la Maljuna (mortinto en 1462), kaj Katarzyna (vidvino de Jan Peckau), menciita en aliaj fontoj kiel Katarzyna "Rüdiger gente Modlibog" (mortinto en 1476). La Watzenrode familio, kiel la Kopernik-familio, venis de Silezio de proksime de Świdnica (Schweidnitz), kaj post 1360 ekloĝis en Toruń. Ili baldaŭ iĝis unu el la plej riĉaj kaj la plej multe influaj patriciaj familioj. Tra la ampleksaj familiparencecoj de la Watzenrodes per geedziĝo, Koperniko estis parenca al riĉaj familioj de Toruń, Danzig kaj Elbląg (Elbing), kaj al elstaraj nobelgentoj de Prusio: la Czapski, Działyński, Konopacki kaj Kościelecki. La Modlibógs (la pola nomo signifas "Preĝu al dio") estis elstara pola familio kiu estis konata en la historio de Pollando ekde 1271.  Lucas kaj Katherine havis tri filojn: Lucas Watzenrode la Pli Juna (1447-1512), kiu iĝus Episkopo de Varmio kaj la baptopatro de Koperniko; Barbara, la baptopatrino de la astronomo (mortinto post 1495); kaj Christina (mortinto antaŭ 1502), kiu en 1459 geedziĝis kun la Toruń-komercisto kaj urbestro, Tiedeman von Allen.
Lucas Watzenrode la Plejaĝa, riĉa komercisto kaj en 1439-62 prezidanto de la juĝistaro, estis firmanima kontraŭulo de la Ordeno de germanaj kavaliroj. En 1453 li estis la delegito de Toruń ĉe la Grudziądz (Graudenz) konferenco kiuj planis la ribelon kontraŭ ili. Dum la rezultinta Dektrijara Milito (1454-66), li aktive apogis la militinveston de la prusaj grandurboj kun grandaj monaj subvencioj (nur parto de kiuj li poste reakiris), kun politika agado en Toruń kaj Danzig, kaj per propra batalado en bataloj ĉe Łasin (Lessen) kaj Malbork (Marienburg). Li mortis en 1462.
Lucas Watzenrode la Pli Juna, la patrinflanka onklo kaj baptopatro de la astronomo, estis edukita ĉe la Universitato de Krakovo (nun Jagelona Universitato) kaj en la universitatoj de Kolonjo kaj Bolonjo. Li estis akra kontraŭulo de la teŭtona ordo,  kaj ĝia grandmajstro siatempe nomis lin "la diablo enkorpa".. En 1489 Watzenrode estis elektita Episkopo de Varmio (Ermeland, Ermland) kontraŭ la prefero de reĝo Kazimiro la 4-a (Pollando-Litovio), kiu esperis instali sian propran filon en tiu sidloko. Kiel rezulto, Watzenrode kverelis kontraŭ la reĝo ĝis la morto de Kazimiro la 4-a tri jarojn poste. Watzenrode tiam povis formi proksimajn rilatojn kun tri sinsekvaj polaj monarkoj: Johano la 1-a Alberto, Aleksandro, kaj Sigismondo la 1-a. Li estis amiko kaj esenca konsilisto al ĉiu reganto, kaj lia influo tre fortigis la rilatojn inter Varmio kaj Pollando mem. Watzenrode estis konsiderita la plej potenca viro en Varmio, kaj lia riĉeco, ligoj kaj influo permesis al li certigi la edukon kaj karieron de Koperniko kiel kanoniko en katedralo de Frombork.
La teorio de Koperniko
Fizike, la teorio de Koperniko estis ridinda kaj neebla: la tiam regnanta fiziko estis la fiziko de Aristotelo, kiu konsideris la Teron en la centro de la universo, ne pro naiveco aŭ homa vanteco, sed pro la natura elveno de naturo mem: la mondo konsistas el kvar elementoj (tero, akvo, fajro, aero), kiu nature moviĝas al la centro de la Tero aŭ foren: aero fluas, fajro supreniras, akvo falas kaj tero alfundiĝas. Ĉar tero nature moviĝas al la centro de la universo, ĉe tia centro estas, tute atendite, la Tero mem, kovrita de maroj de akvo. La Suno kaj la planedoj, dume, konsistas el kvina elemento, la kvintesenco, kiu nature cirkliras ĉirkaŭ la centro, la Tero. Cirklirado, laŭ Aristotelo, estas la plej perfekta moviĝo. Ĉi tiu lasta supozo de Aristotelo estis konservita en la sistemo de Koperniko, kaj fariĝis la ĉefa difekto de la teorio.
Matematike, la teorio de Koperniko estis pli facila ol tiu de Ptolemeo, sed ne pli preciza aŭ eĉ pli simpla: same kiel Ptolemeo, Koperniko uzis multe da cirkloj kaj cirkloj en cirkloj por modeli planedan movon. Kial? Ĉar la radika eraro de Ptolemeo ne estas lia loko por la Tero: malgraŭ ĉio, se movo estas relativa, sekve oni povus konstrui precizan teorion, kiu metus la Teron en la centron. Kontraŭe, lia radika eraro estas tio, ke li uzis cirklojn kaj ne elipsojn. Kaj Koperniko simile eraris! Okcidentanoj, sekvinte Aristotelon, kredis ke la ĉiela movo estas sendifekta, tial ĝi konsistas el cirkloj.
Tial la teorio de Koperniko ne povis tute venki ĝis Keplero anstataŭigis la cirklojn per elipsojn.
La venko de Koperniko ne nur renversis Ptolemeon, sed, pli grave, Aristotelon. Pro tio, ĝi necesigis novan fizikon, la fizikon de Neŭtono. Ĝi ankaŭ renversis la filozofion kaj sciencon de Aristotelo kaj, tiel, malfermis la pordon por la moderna scienco de Galileo, Bakono kaj Kartezio kaj, post tempo, por modernismo.
Tombejo kaj sekvo
Dum elfosado en la katedralo de Frombork ĉe la Balta Maro, arkeologoj trovis en la jaro 2005 kranion kaj aliaj restaĵoj de homa korpo apud la altaro. La korpo estis tiu de ĉirkaŭ 70-jara viro, kiu mortis en la 16-a jarcento. En 2008 komparo de la DNA de unu el la dentoj kaj de la femuro kun tiu de du haroj trovitaj en libro de la astronomo, konservita ĉe la universitato de Upsala (Svedio), evidentiĝis ke temas tre verŝajne pri la sama persono. Jurmedicina vizaĝrekonstruo laŭ la trovita kranio similegas al la portretoj konataj de Koperniko.
Koperniko (pole: Kopernik) estas pola-germana filmbiografio reĝisorita de Eva Petelska kaj Ĉeslavo Petelski el 1972 okaze de jubileo de 500-jaroj de naskiĝo de la fama astronomo Nikolao Koperniko. Preskaŭ samtempe estis farita samtitola filmserio.
- Dava Sobel, A More Perfect Heaven: How Copernicus Revolutionized the Cosmos, Walker and Co., 2011. ISBN: 978-0-8027-1793-1. "Unu el la timoj de Koperniko – skribas lia biografiistino Dava Sobel – estis ke “astronomoj liaj kolegoj (ligitaj al la aristotela. ptolomea sistemo. Ndt) – observintus ke la Tero ĝuste okupis la centron de ĉio ne pro tio ke la loĝejo de la homa genro meritus honorpostenon, sed male, pro tio ke en la centrn akumuliĝas kaj kuŝas ĉiu speco da materiaĵoj kaj pro tio ke falo, ŝanĝo, kaj morto estis la destino de la loĝantoj de la Tero. Kurtavorte, la Tero estis la centro ne pro tio ke ĝi estis la kulmino sed la spurejo de la krejtaro, kaj oni ne aŭdacu lokigi la sunon, kiun multaj epitetas la ĉiela lumo, en la inferan postenon poziciitan centren de la kosmo. La perdo de la fisika centreco de la Tero absolute ne signifis, do, por Koperniko perdo de la vera centreco de la homo ligita prefere al lia spirita naturo, al liaj eksterordinaraj apartaĵoj kaj unikaj (penso, libero, racio, amo...), kaj ne certe al lia geografia pozicio."
