[Sidenote: Lorenzo de' Medici, his villas, gardens, and philosophy.] Lorenzo de' Medici, the grandson of Cosmo, used every exertion to increase the rising taste, generously permitting his manuscripts to be copied. Nor was it alone to literature that he extended his patronage. In his beautiful villa at Fiesole the philosophy of the old times was revived; his botanic garden at Careggi was filled with Oriental exotics. From 1470 to 1492, the year of his death, his happy influence continued. He lived to witness the ancient Platonism overcoming the Platonism of Alexandria, and the pure doctrine of Aristotle expelling the base Aristotelian doctrine of the schools. [Sidenote: Effects instantly produced by the Greek language.] The last half of the fifteenth century revealed to Western Europe two worlds, a new one and an old; the former by the voyage of Columbus, the latter by the capture of Constantinople; one destined to revolutionize the industrial, the other the religious condition. Greek literature, forced into Italy by the Turkish arms, worked wonders; for Latin Europe found with amazement that the ancient half of Christendom knew nothing whatever of the doctrine or of the saints of the West. Now was divulged the secret reason of that bitter hatred displayed by the Catholic clergy to Grecian learning. [Sidenote: Causes of the prevailing dislike of Greek.] It had sometimes been supposed that the ill-concealed dislike they had so often shown to the writings of Aristotle was because of the Arab dress in which his Saracen commentators had presented him; now it appeared that there was something more important, more profound. It was a terror of the Greek itself. Very soon the direction toward which things must inevitably tend became manifest; the modern languages, fast developing, were making Latin an obsolete tongue, and political events were giving it a rival--Greek--capable of asserting over it a supremacy; and not a solitary rival, for to Greek it was clear that Hebrew would soon be added, bringing with it the charms of a hoary antiquity and the sinister learning of the Jew. With a quick, a jealous suspicion, the ecclesiastic soon learned to detect a heretic from his knowledge of Greek and Hebrew, just as is done in our day from a knowledge of physical science. The authority of the Vulgate, that corner-stone of the Italian system, was, in the expectation of Rome, inevitably certain to be depreciated; and, in truth, judging from the honours of which that great translation was soon despoiled by the incoming of Greek and Hebrew, it was declared, not with more emphasis than truth, yet not, perhaps, without irreverence, that there was a second crucifixion between two thieves. Long after the times of which we are speaking, the University of Paris resisted the introduction of Greek into its course of studies, not because of any dislike to letters, but because of its anticipated obnoxious bearing on Latin theology.
