 In the process of painting the ceiling, Michelangelo made studies for different figures, of which some, such as that for "The Libyan Sibyl" have survived, demonstrating the care taken by Michelangelo in details such as the hands and feet.The Prophet Jeremiah, contemplating the downfall of Jerusalem, is an image of the artist himself.Michelangelo's relief of the "Battle of the Centaurs", created while he was still a youth associated with the Medici Academy, is an unusually complex relief in that it shows a great number of figures involved in a vigorous struggle.
