In his private life Cosimo was the simplest and most unpretentious of tyrants, and lived the life of a wealthy merchant-burgher of the day in its nobler aspects. He was an ideal father, a perfect man of business, an apparently kindly fellow-citizen to all. Above all things he loved the society of artists and men of letters; Brunelleschi and Michelozzo, Donatello and Fra Lippo Lippi--to name only a few more intimately connected with him--found in him the most generous and discerning of patrons; many of the noblest Early Renaissance churches and convents in Florence and its neighbourhood are due to his munificence--San Lorenzo and San Marco and the Badia of Fiesole are the most typical--and he even founded a hospital in Jerusalem. To a certain extent this was what we should now call "conscience money." His friend and biographer, Vespasiano Bisticci, writes: "He did these things because it appeared to him that he held money, not over well acquired; and he was wont to say that to God he had never given so much as to find Him on his books a debtor. And likewise he said: I know the humours of this city; fifty years will not pass before we are driven out; but the buildings will remain." The Greeks, who came to the Council of Florence or fled from the in-coming Turk, stimulated the study of their language and philosophy--though this had really commenced in the days of the Republic, before the deaths of Petrarch and Boccaccio--and found in Cosimo an ardent supporter. He founded great libraries in San Marco and in the Badia of Fiesole, the former with part of the codices collected by the scholar Niccolò Niccoli; although he had banished the old Palla Strozzi, the true renovator of the Florentine University, into hopeless exile. Into the Neo-Platonism of the Renaissance Cosimo threw himself heart and soul. "To Cosimo," writes Burckhardt, "belongs the special glory of recognising in the Platonic philosophy the fairest flower of the ancient world of thought, of inspiring his friends with the same belief, and thus of fostering within humanistic circles themselves another and a higher resuscitation of antiquity." In a youth of Figline, Marsilio Ficino, the son of a doctor, Cosimo found a future high priest of this new religion of love and beauty; and bidding him minister to the minds of men rather than to their bodies, brought him into his palace, and gave him a house in the city and a beautiful farm near Careggi. Thus was founded the famous Platonic Academy, the centre of the richest Italian thought of the century. As his end drew near, Cosimo turned to the consolations of religion, and would pass long hours in his chosen cell in San Marco, communing with the Dominican Archbishop, Antonino, and Fra Angelico, the painter of mediæval Paradise. And with these thoughts, mingled with the readings of Marsilio's growing translation of Plato, he passed away at his villa at Careggi in 1464, on the first of August.
