From about 1464 the members of the Wool Guild wanted to have twelve statues of people from the Old Testament of the Bible carved for the Florence Cathedral. These statues were to go on the buttresses all around the outside walls, high up near the roof. Two statues had already been made by Donatello and his assistant, Agostino di Duccio. Duccio was asked to carve a statue of David. He began carving the statue's feet, chest and a hole between the legs. He stopped making the statue when his master, Donatello, died in 1466. Antonio Rossellino then worked on the statue for two years. The block of stone was untouched for 33 years and was left in the cathedral workshop where it was getting damaged by the weather. Michelangelo began working on David on September 13, 1501. It was finished on September 8, 1504.
