Figura serpentinata - 'serpentine figure' - is the Mannerist convention of composing a figure as an ascending spiral, so that the body twists through several axes and looks finished from every viewpoint. Developed in the sixteenth century out of Michelangelo's extreme contrapposto, it became the era's signature device: Benvenuto Cellini described his Perseus as a figura serpentinata, and Giambologna's group sculptures push the spiral to spectacular effect. The pose does not describe action so much as display grace - the figure seems to rotate before the viewer, dynamic and weightless. It spread from Italian sculpture and drawing across European art, and any later work built on coiling, spiraling poses owes it a debt.
