Much of the influence acquired by Cosimo, and transmitted to his descendants, was due to sympathy with the intellectual movement of the age. He had received a solid education; and though he was not a Greek scholar, his mind was open to the interests which in the fifteenth century absorbed the Florentines. He collected manuscripts, gems, coins, and inscriptions, employing the resources of his banking house and engaging his commercial agents in this work. Painters and sculptors, no less than scholars and copyists, found in him a liberal patron. At the death of his son Piero the treasures of the Casa Medici, not counting plate and costly furniture, were valued at 30,000 golden florins.[133] The sums of money spent by him in building were enormous. It was reckoned that, one year with another, he disbursed from 15,000 to 18,000 golden florins annually in edifices for the public use.[134] Of these the most important were the Convent of S. Marco, which altogether cost about 70,000 florins; S. Lorenzo, which cost another 40,000; and the Abbey of Fiesole. On his own palace he expended 60,000 florins, while the building of his villas at Careggi and Cafaggiuolo implied a further large expenditure. Not a shilling of this money was wasted; for while Cosimo avoided the reproach of personal extravagance, he gave work to multitudes of labourers, who received their wages regularly every Saturday at his office. To this free use of wealth in the employment of artisans may be ascribed the popularity of the Medici with the lower classes, which was more than once so useful to them at a perilous turn of fortune.

Comprehending the conditions under which tyranny might be successfully practised in the fifteenth century, Cosimo attached great value to this generosity. He used, in later life, to regret that 'he had not begun to spend money upon public works ten years earlier than he did.'[135] Every costly building that bore his name, each library he opened to the public, and all the donations lavished upon scholars served the double purpose of cementing the despotism of his house and of gratifying his personal enthusiasm for culture. Superstition mingled with these motives of the tyrant and the dilettante. Knowing that much of his wealth had been ill-gotten, he besought the Pope, Eugenius, to indicate a proper way of restitution. Eugenius advised him to spend 10,000 florins on the Convent of S. Marco. Thereupon Cosimo laid out considerably more than four times that sum, adding the famous Marcian Library, and treating the new foundation of the Osservanza, one of the Pope's favourite crotchets, with more than princely liberality.[136]
