Cosimo de' Medici (1393-1464), a banker and ruler of Florence, spent great sums in collecting and copying manuscripts. Vespasiano, a fifteenth- century bookseller of Florence, has left us an interesting picture of the work of Cosimo in founding (1444) the great Medicean library [16] at Florence (R. 130) and of the difficulties of book collecting in the days before the invention of printing. [Illustration: FIG. 71. BOOKCASE AND DESK IN THE MEDICEAN LIBRARY AT FLORENCE (Drawn from a photograph) This library was founded in 1444. It contains to-day about 10,000 Greek and Latin manuscripts, many of them very rare, and of a few the only copies known. The building was designed by Michael Angelo, and its construction was begun in 1525. The bookcases are of about this date. It shows the early method of chaining books to the shelves, and cataloguing the volumes on the end of each stack.] Under Cosimo's grandson, Lorenzo the Magnificent, who died in 1492, two expeditions were sent to Greece to obtain manuscripts for the Florentine library. Vespasiano also describes for us the books collected (c. 1475-80) for the great ducal library at Urbino (R. 131), the greatest library in the Christian world at the time of its completion, and the work of Pope Nicholas V [17] (1447-1455) in laying the foundations (1450) for the great Vatican Library at Rome (R. 132). Nicholas was an enthusiast in the new movement, and formed a plan for the translation of all the Greek writers into Latin. A later Pope, Leo X (1513-1521), planned to make Rome the international center for Greek learning. THE MOVEMENT EXTENDS TO OTHER COUNTRIES. Petrarch made his first great find in 1333, and up to 1450 the Revival of Learning, often termed the Renaissance, was entirely an Italian movement. By that date the great work in Italy had been done, and the Italians were once more in possession of the literature and history of the past. With them the movement was literary, historical, and patriotic in purpose and spirit. With them the movement was known as _humanism_, from an old Roman word (_humanitas_) meaning culture, and this term came to be applied to the new studies in all other lands. In their work with the literatures, inscriptions, coins, and archaeological remains of the Greeks and Romans, their own literature, history, mythology, and political and social life was reconstructed. The methods employed were the methods used in modern science, and the result was to develop in Italy a new type of scholar, possessed of a literary, artistic, and historical appreciation unknown since the days of ancient Rome, and with the greatest enthusiasm for Latin as a living language.
