Soon after this he made a beautiful, sleeping Cupid, and when the young Lorenzo de Medici saw it he advised Michael Angelo to bury it in the ground for a season, and thus make it look like an antique marble; after this was done, Lorenzo sent it to Rome and sold it to the Cardinal Riario, and gave the sculptor thirty ducats. In some way the truth of the matter reached the ears of the Cardinal, who sent his agent to Florence to find the artist. When Michael Angelo heard that two hundred ducats had been paid for his Cupid, he knew that he had been deceived. The Cardinal's agent invited him to go to Rome, and he gladly went. The oldest existing writing from the hand of Michael Angelo is the letter which he wrote to Lorenzo to inform him of his arrival in Rome. He was then twenty-one years old, and spoke with joy of all the beautiful things he had seen. Not long after he reached Rome he made the statue of the "Drunken Bacchus," now in the Uffizi Gallery, and then the Virgin Mary sitting near the place of the cross and holding the body of the dead Christ. The art-term for this subject is "La Pieta." From the time that Michael Angelo made this beautiful work he was the first sculptor of the world, though he was but twenty-four years old. The Pieta was placed in St. Peter's Church, where it still remains. The next year he returned to Florence. He was occupied with both painting and sculpture, and was soon employed on his "David," one of his greatest works. This statue weighed eighteen thousand pounds, and its removal from the studio in which it was made to the place where it was to stand, next the gate of the Palazzo Vecchio, was a difficult undertaking. It was at last put in place on May 18, 1504; there it remained until a few years ago, when, on account of its crumbling from the effect of the weather, it was removed to the Academy of Fine Arts by means of a railroad built for the purpose. About this time a rivalry sprang up between Michael Angelo and Leonardo da Vinci. They were very unlike in their characters and mode of life. Michael Angelo was bitter, ironical, and liked to be alone; Leonardo loved to be gay and to see the world; Michael Angelo lived so that when he was old he said, "Rich as I am, I have always lived like a poor man;" Leonardo enjoyed luxury, and kept a fine house, with horses and servants. They had entered into a competition which was likely to result in serious trouble, when Pope Julius II. summoned Michael Angelo to Rome. The Pope gave him an order to build him a splendid tomb; but the enemies of the sculptor made trouble for him, and one morning he was refused admission to the Pope's palace. He then left Rome, sending this letter to the Pope: "Most Holy Father, I was this morning driven from the palace by the order of your Holiness. If you require me in future you can seek me elsewhere than at Rome."
