Michelangelo's sculpture of David was sculpted out of Marble. The statue was supposed to sit up on the buttress of the cathedral but due to its size, it was placed in the principle city square. The depiction of David in Michelangelo's statue is one of a more mature young man than that of Donatello's sculpture. You can see the well-developed muscle structure, and according to the reading assignment, this was the first sculpture of its type to have such a stoic and focused gaze. (Stokstad, 2013)
