They banished many citizens and set down (_i.e._ made _Grandi_ or nobles) many disloyal families and did many things favourable to the city. During their rule the Balìa given to various citizens expired, the Squittini, or Scrutinies, came to an end, and the borse, or ballot-bags, remained for five years in the hands of the Accopiatori, that is to say, the borse of the Priors, so that they could make whomsoever they would Priors and Gonfaloniers of Justice. In January my name was the first to be drawn from the borse as Gonfalonier, and in my time no one was banished nor was ill done to any one. I caused the sentence of death passed upon Francesco Guadagni, and upon some others whom I found in the hands of the Captain of the Balìa, to be commuted to perpetual imprisonment. Also I ordered the armed men who stood at the door of the Palace to be removed and the Palace and the Piazza to be kept as they were before the revolution, and I prolonged the league with the Signory of Venice for ten years. “Seldom has a citizen returning triumphant from a victory,” writes Machiavelli, “been received by such a concourse of people and with such demonstrations of affection as was Cosimo on his return from exile, saluted by all as the benefactor of the people and the father of his country.”[25] It was probably while at Venice that Cosimo bought the slave girl by whom he had a son, Carlo, who was brought up for the Church and recognised as belonging to the family. He inherited his father’s tastes, and was employed by him and by Piero to buy books, manuscripts, statues, &c., in Rome. He became a Canon of the cathedral in Florence and Arciprete at Prato, where he died. The number of female slaves imported into Florence in the fourteenth and fifteenth centuries was a most disturbing element in family life and the cause of much jealousy, as can be gathered from the novelists of the time. Nearly all came from Caffa (Theodosia in the Crimea) and from the mouth of the Tana. Caffa must have been practically a Genoese settlement, as the Genoese consul levied a tax on every slave that passed through the town, and they were many. Hundreds of Circassian, Tartar, Armenian, Georgian, Arab, Turkish, Russian, and Greek girls were shipped, chiefly to Genoa and to Venice, where the trade had existed since the eighth century. In Florence the duty paid on every slave that entered the city must have brought in a considerable sum to the Commune, as owners were obliged to register every newly-acquired slave within two months and to have him or her baptized, if the rite had not been already performed. One would have thought that good Catholics might have had some qualms of conscience about keeping a Christian as a slave, but Sacchetti writes:
