In 1453 Constantinople was taken by the Turks, and many Greek scholars, with their manuscripts, fled into Italy, where they began teaching their language and literature, and especially the philosophy of Plato. There had been little or no knowledge of Greek in western Europe during the Middle Ages, and only a very imperfect knowledge of the Latin classics. Ovid and Statius were widely read, and so was the late Latin poet, Boethius, whose _De Consolatione Philosophiae_ had been translated into English by King Alfred and by Chaucer. Little was known of Vergil at first hand, and he was popularly supposed to have been a mighty wizard, who made sundry works of enchantment at Rome, such as a magic mirror and statue. Caxton's so-called translation of the _Aeneid_ was in reality nothing but a version of a French romance based on Vergil's epic. Of the Roman historians, orators, and moralists, such as Livy, Tacitus, Caesar, Cicero, and Seneca, there was almost entire ignorance, as also of poets like Horace, Lucretius, Juvenal, and Catullus. The gradual rediscovery of the remains of ancient art and literature which took place in the 15th century, and largely in Italy, worked an immense revolution in the mind of Europe. Manuscripts were brought out of their hiding places, edited by scholars, and spread abroad by means of the printing-press. Statues were dug up and placed in museums, and men became acquainted with a civilization far more mature than that of the Middle Age, and with models of perfect workmanship in letters and the fine arts.
