moment realism and beauty have kissed one another: for reality is not enough, as Alberti will find some day, it is necessary to find and to express the beauty there also. It was an age that was learning to enjoy itself. The world and the beauty of the world laid bare, partly by the study of the ancients, partly by observation, really almost a new faculty, were enough; that conscious paganism which later, but for the great disaster, might have emancipated the world, had not yet discovered itself; in Cosimo's day art was still an expression of joy, impetuous, unsophisticated, simple. In this world of brief sunshine Cosimo appears to us very delightfully as the protector of the arts, the sincere lover of learning, the companion of scholars. To him in some sort the world owes the revival of the Platonic Philosophy, for the Greek Argyropolis lived in his house, and taught Piero his son and Lorenzo his grandson the language of the Gods. When Gemisthus Pletho came to Florence, Cosimo made one of his audience, and was so moved by his eloquence that he determined to establish a Greek academy in the city on the first opportunity. He was the dear friend of Marsilio Ficino, and he founded the Libraries of S. Marco and of the Badia at Fiesole. The great humanists of his time, Leonardo Bruni, Carlo Marsuppini, Poggio and Niccolo de' Niccoli were his companions, and in his palace in Via Larga, and in his villas at Careggi and Poggio a Caiano, he gathered the most precious treasures, rare manuscripts, and books, not a few antique marbles and jewels, coins and medals and statues, while he filled the courts and rooms, built and decorated by the greatest artists of his time, with the statues of Donatello, the pictures of Paolo Uccello, Andrea del Castagno, Fra Filippo Lippo, and Benozzo Gozzoli. Cosimo, says Gibbon, "was the father of a line of princes whose name and age are almost synonymous with the restoration of learning; his credit was ennobled with fame; his riches were dedicated to the service of mankind; he corresponded at once with Cairo and London, and a cargo of Indian spices and Greek books were often imported in the same vessel." While Burckhardt, the most discerning critic of the civilisation of the Renaissance, tells us that "to him belongs the special glory of recognising in the Platonic philosophy the fairest flower of the ancient world of thought, and of inspiring his friends with the same belief."
