Donato di Niccolò di Betto Bardi, or Donatello, was born in Florence in 1366 and died there in 1466. He is remembered as one of the finest sculptors of his era, known as the Renaissance. During his long career, he produced many works of art so it can be quite difficult to pinpoint a particular sculpture as being 'his most famous.' In the early years of his career, for example, his sculpture of Saint George was considered a masterpiece. This marble statue was created for the guildhall at Orsanmichele. Another important piece is the statue of David, which Donatello created for the Medici family and which is probably the most famous piece of art from the later years of his career.
