A selection of four portraits of the statues that can be found at the Piazza della Signoria. They are, in no particular order:
(1) A replica of Michelangelo’s David
(2) Bartolomeo Ammannati’s Fountain of Neptune
(3) An early Giambologna’s The Rape of the Sabine Women
(4) Benvenuto Cellini’s bronze Perseus With the Head of Medusa
My favorite among these is The Rape (in this context, abduction) of the Sabine Women, for the complexity of its structure. The statue morphs masterfully along with your perspective, but every angle will allow the viewer to appreciate the fierce expressions etched onto their faces.
