Lorenzo (1492-1519), Duke of Urbino and nephew of Pope Leo X, is portrayed by Michelangelo in deep thought, as Machiavelli’s Prince. The allegories on the sarcophagus are a rather muscular female Dawn waking from sleep and a tired Dusk about to fall asleep. The face of the male Dusk is rather rough to emphasize tiredness. Sculptures by Michelangelo in the New Sacristy of the Medici Chapels.
