already before the time of these cultivated Medici "bosses," Florence had produced much beautiful art. Giotto's tower (Giotto, born 1266, died 1337) and the glorious Duomo (by Brunellesco, born 1377, died 1446) already existed. Towards the end of the fourteenth century Florence became the centre of the rediscovery, restoration, and imitation of antique art (the "Renaissance" in its narrower sense). Artistic productions, unlike philosophical thought and scientific discovery, are the ornaments and expression rather than the creative substance of history, and here we cannot attempt to trace the development of the art of Filippo Lippi, Botticelli, Donatello (died 1466), Leonardo da Vinci (died 1519), Michelangelo (1475-1564), and Raphael (died 1520). Of the scientific speculation of Leonardo we have already had occasion to speak.

In 1453, as we have related, Constantinople fell. Throughout the next century the Turkish pressure upon Europe was heavy and continuous. The boundary line between Mongol and Aryan, which had lain somewhere east of the Pamirs in the days of Pericles, had receded now to Hungary. Constantinople had long been a mere island of Christians in a Turk-ruled Balkan Peninsula. Its fall did much to interrupt the trade with the East.
Of the two rival cities of the Mediterranean, Venice was generally on much better terms with the Turks than Genoa. Every intelligent Genoese sailor fretted at the trading monopoly of Venice, and tried to invent some way of getting through it or round it. And there were now new peoples taking to the sea trade, and disposed to look for new ways to the old markets because the ancient routes were closed to them. The Portuguese, for example, were developing an Atlantic coasting trade. The Atlantic was waking up again after a vast period of neglect that dated from the Roman murder of Carthage. It is rather a delicate matter to decide whether the western European was pushing out into the Atlantic or whether he was being pushed out into it by the Turk, who lorded it in the Mediterranean until the Battle of Lepanto (1571). The Venetian and Genoese ships were creeping round to Antwerp, and the Hansa town seamen were coming
