At the commencement of the Erudite Period Arabic literature still predominated in medicine. Rhazes, Haly-Abbas, and Avicenna were universally invoked and explained. But a taste for Greek literature began to prevail in the universities of Italy, and was finally extended to every part of Europe, especially after the taking of Constantinople by Mahomet II, Emperor of the Turks, in 1453. This disaster, which at first bade fair to be a mortal blow to Greek literature and language, strange to say, served only to hasten their resurrection in the Occident. Constantinople having been given over to pillage at this time, most of its learned men escaped, carrying with them all manuscripts that could be seized; most of these found refuge in Italy, and enlightened protectors in the allpowerful prince of the house of Medici, in Florence, in the popes at Rome, and in Alphonso, of Arragon, King of Naples and Sicily. Everywhere these fugitives spread the knowledge{101} of the masterpieces of Greek literature and art, and in this way a taste for books, libraries, and sound erudition was diffused, while the Greek and Latin classics were hunted up and published with great patience and ardor; thus the works of the old writers were edited, translated, commented upon, and everywhere disseminated throughout Europe. Among those who devoted themselves to the thankless task of editing, and purifying from interpolations, the works of the classic writers was Nicholas Léonicenus, born near Vincenza in the year 1428, who studied medicine at Padua and taught it for more than sixty years at Ferrara. He possessed great vigor of mind, with purity of manners and serenity of soul, and was the first to translate directly from Greek into Latin the aphorisms of Hippocrates and portions of the writings of Galen. He combated in every way the infatuation of his contemporaries for the Arabians and their lore, and called attention to many of the errors of men who, like Pliny the naturalist, had fallen for lack of fully understanding the Greek authors they compiled. At the ripe age of ninety-six he died, regretted by all.
