To Lorenzo, Duke of Urbino, the titular head of the family, was committed the government of Florence. During their exile, wandering from court to court in Italy, the Medici had forgotten what it was to be burghers, and had acquired the manners of princes. Leo alone retained enough of caution to warn his nephew that the Florentines must still be treated as free people. He confirmed the constitution of the Signory and the Privy Council of seventy established by his father, bidding Lorenzo, while he ruled this sham republic, to avoid the outer signs of tyranny. The young duke at first behaved with moderation, but he could not cast aside his habits of a great lord. Florence now for the first time saw a regular court established in her midst, with a prince, who, though he bore a foreign title, was in fact her master. The joyous days of Lorenzo the Magnificent returned. Masquerades and triumphs filled the public squares. Two clubs of pleasure, called the Diamond and the Branch--badges adopted by the Medici to signify their firmness in disaster and their power of self-recovery--were formed to lead the revels. The best sculptors and painters devoted their genius to the invention of costumes and cars. The city affected to believe that the age of gold had come again. XXIII Fortune had been very favourable to the Medici. They had returned as princes to Florence. Giovanni was Pope. Giuliano was Gonfalonier of the Church. Giulio was Cardinal and Archbishop of Florence. Lorenzo ruled the city like a sovereign. But this prosperity was no less brief than it was brilliant. A few years sufficed to sweep off all the chiefs of the great house. Giuliano died in 1516, leaving only a bastard son Ippolito. Lorenzo died in 1519, leaving a bastard son Alessandro, and a daughter, six days old, who lived to be the Queen of France. Leo died in 1521. There remained now no legitimate male descendants from the stock of Cosimo. The honours and pretensions of the Medici devolved upon three bastards--on the Cardinal Giulio, and the two boys, Alessandro and Ippolito. Of these, Alessandro was a mulatto, his mother having been a Moorish slave in the Palace of Urbino; and whether his father was Giulio, or Giuliano, or a base groom, was not known for certain. To such extremities were the Medici reduced. In order to keep their house alive, they were obliged to adopt this foundling. It is true that the younger branch of the family, descended from Lorenzo, the brother of Cosimo, still flourished. At this epoch it was represented by Giovanni, the great general known as the Invincible, whose bust so strikingly resembles that of Napoleon. But between this line of the Medici and the elder branch there had never been true cordiality. The Cardinal mistrusted Giovanni. It may, moreover, be added, that Giovanni was himself doomed to death in the year 1526.
