This episode examines the extraordinary tomb of Lorenzo de' Medici in the New Sacristy. The allegorical figures of "Dawn" and "Dusk" are two of Michelangelo's most elegant statues, while the "Effigy of Lorenzo de' Medici" is a clear allusion to the Classical "thinker" pose. We also analyze how the sculptural groups interact with the general architectural program of the room.
