The house was built by Michelozzo di Bartolommeo, then forty years old, for Cosimo de’ Medici, in the first half of the fifteenth century. Filippo Brunelleschi, the greatest architect of modern Italy, had made a design for the palace of the rich and art-loving citizen, who was one of his best friends. It was the plan of a vast building, unenclosed on all sides, and fronting towards the square of San Lorenzo, where stood the church, the restoration of which had been begun by the same artist for Cosimo’s father. But cautious, calculating Cosimo, fearing that a house on so magnificent a scale as that designed by Brunelleschi, even if not beyond his means, would exceed the ordinary dimensions of a citizen’s dwelling, and might excite popular jealousy, gave the preference to Michelozzo’s more limited design.[1] Brunelleschi took offence at this neglect of himself, and destroyed his model. Yet Cosimo acted more prudently than did, at a later period, a countryman of his, who began to build from the design of the same master the largest edifice that perhaps a private citizen ever undertook, and who consequently lost much in public estimation and respect. In the second half of the fourteenth century the Medici had removed into the neighbourhood of San Lorenzo’s church, where their residence occupied the ground adjoining Cosimo’s palace on the north, and remained in the possession of his brother Lorenzo, the founder of the subsequent ducal line.[2] Their original dwelling-place was in the centre of the old town, on the market-place, inside the first wall. Many of the foremost families were once settled here, and even now the lover of history and antiquity will find among the damp stalls of the butcher, fishmonger, and dealer in vegetables, sparse remains of past and, so far as concerns this part of the town, better days. The little church of San Tommaso in this place was in the patronage of the Medici from time immemorial. The Medici did not belong to the historic families of the city on the Arno. The first trace of them is to be found about the end of the twelfth century in Giambuono, of whose extraction nothing is known. The coat of arms exhibits red balls in a gold field, whose number and arrangement were different at different times, until, under Cosimo’s son, the coat of arms assumed the form which it has ever since retained. From these balls (_palle_) the dependents of the family bore the name of Palleschi. From whence the Medici came, what was the meaning of the coat of arms, no one knew. Genealogical dreams have gone as far back as Perseus and the apples of the Hesperides, whilst modest historians have contented themselves with the time of Charlemagne, and the mountainous land north of Florence, known by the name of Mugello, where the family had always held important possessions, designated as their home.
