Anonymous 16th-century portrait of Donatello.  There are no contemporary portraits of the artist, so this likeness is questionable.  The painter most likely copied from various existing models and rendered a more idealized picture.

Donatello's David, completed probably around 1440, first free-standing nude statue since the end of the Roman Empire.  It is located in Florence in the Museo Nazionale del Bargello.
