The tomb of Piero and Giovanni de Medici, completed in 1472, was the Medici’s first major commission from Italian painter and sculptor Andrea del Verrocchio. The sarcophagus is unique both in its composition and its materials. The tomb is set in an archway and uses a combination of coloured marble and porphyry, complimented by decorative bronze ornamentation. Verrocchio was a master of both stone and metalwork, which sets this tomb apart from others of this period. This work is significant not only because it marks the start of the Medici’s lifelong patronage of Verrocchio, but also because it is most likely the inspiration piece for the marble bench that appears in da Vinci’s Annunciation. This provides evidence that Leonardo da Vinci was active in Verrocchio's workshop, and both masters may have had a hand in painting Annunciation
