Contrapposto is a natural, weight-shifting pose in sculpture and figure painting.
Contrapposto (Italian: 'counterpoise') describes the stance in which a figure's weight rests on one leg, causing the hips and shoulders to tilt in opposite directions — the natural stance of a relaxed human body. The ancient Greeks discovered it around 480 BCE, and it transformed sculpture instantly. Before contrapposto, figures stood rigidly frontal (the 'kouros' pose, borrowed from Egypt). After, they turned, twisted, breathed. Polyclitus codified the ideal proportions in his lost treatise Kanon; his Doryphoros (Spear Bearer) is the textbook example. Michelangelo's David uses contrapposto at monumental scale: he stands still but seems coiled. The pose migrated from sculpture into painting and became the default grammar of the human body in Western art. The pose first appears fully realized in Greek sculpture of the early 5th century BCE, most famously in the bronze Kritios Boy, which marks a decisive break from the rigid, symmetrical frontal stance (kouros) that had dominated Archaic Greek sculpture for the preceding two centuries. By shifting weight onto one 'engaged' leg while the other relaxes, the sculptor introduces a subtle S-curve through the spine and a diagonal counter-tilt between hips and shoulders that makes stone appear to breathe rather than merely stand. Polykleitos systematized the principle in his lost treatise the 'Canon' and in the surviving Doryphoros ('Spear-Bearer'), establishing mathematical ratios for how weight-shift should relate to overall proportion — turning what began as an observational breakthrough into a teachable, reproducible system. The pose disappeared, along with most classical figural sculpture, during the medieval period, and its rediscovery was a deliberate act of Renaissance archaeology: Donatello's bronze David (c. 1440s) and later Michelangelo's David both consciously revive Polykleitan contrapposto as a signal that sculpture was reclaiming classical antiquity's authority over the human body. The principle remains foundational to figure drawing and sculpture instruction today, precisely because it encodes, in a single compositional device, the difference between a figure that merely occupies space and one that appears to inhabit it.
