Constantine Lascaris (1434 – 1501) was a Greek scholar and grammarian, one of the promoters of the revival of Greek learning in the Italian peninsula, born at Constantinople. After the fall of Constantinople in 1453, he took refuge in Italy, where Francesco Sforza appointed him Greek tutor to his daughter. Here was published his Grammatica Graeca, sive compendium octo orationis partium, remarkable as being probably the first book entirely in Greek issued from the printing press, in 1476.
