Cosimo de' Medici was, I think, the wisest and best ruler that Florence ever had and ranks high among the rulers that any state ever had. But he changed the Florentines from an independent people to a dependent one. In his capacity of Father of his Country he saw to it that his children lost their proud spirit. He had to be absolute; and this end he achieved in many ways, but chiefly by his wealth, which made it possible to break the rich rebel and to enslave the poor. His greatest asset--next his wealth--was his knowledge of the Florentine character. To know anything of this capricious, fickle, turbulent folk even after the event was in itself a task of such magnitude that almost no one else had compassed it; but Cosimo did more, he knew what they were likely to do. By this knowledge, together with his riches, his craft, his tact, his business ramifications as an international banker, his open-handedness and air of personal simplicity, Cosimo made himself a power. For Florence could he not do enough. By inviting the Pope and the Greek Emperor to meet there he gave it great political importance, and incidentally brought about the New Learning. He established the Platonic Academy and formed the first public library in the west. He rebuilt and endowed the monastery of S. Marco. He built and rebuilt other churches. He gave Donatello a free hand in sculpture and Fra Lippo Lippi and Fra Angelico in painting. He distributed altogether in charity and churches four hundred thousand of those golden coins which were invented by Florence and named florins after her--a sum equal to a million pounds of to-day. In every direction one comes upon traces of his generosity and thoroughness. After his death it was decided that as Pater Patriae, or Father of his Country, he should be for ever known. Cosimo died in 1464, leaving an invalid son, Piero, aged forty-eight, known for his almost continuous gout as Il Gottoso. Giovanni and Cosimo had had to work for their power; Piero stepped naturally into it, although almost immediately he had to deal with a plot--the first for thirty years--to ruin the Medici prestige, the leader of which was that Luca Pitti who began the Pitti palace in order to have a better house than the Medici. The plot failed, not a little owing to young Lorenzo de' Medici's address, and the remaining few years of Piero's life were tranquil. He was a quiet, kindly man with the traditional family love of the arts, and it was for him that Gozzoli worked. He died in 1469, leaving two sons, Lorenzo (1449-1492) and Giuliano (1453-1478).
