Jupiter and Thetis is an 1811 painting by the French neoclassical painter Jean Auguste Dominique Ingres, in the Musée Granet, Aix-en-Provence, France. Painted when the artist was yet 31, the work severely and pointedly contrasts the grandeur and might of a cloud-born Olympian male deity against that of a diminutive and half nude nymph. Ingres' subject matter is borrowed from an episode in Homer's Iliad when the sea nymph Thetis begs Jupiter to intervene and guide the fate of her son Achilles; who was at the time embroiled in the Trojan War.
The painting is steeped in the traditions of both classical and neoclassical art, most notably in its grand scale of 136⅝ × 101¼ inches. Ingres creates many visual contrasts between the god and the slithering nymph: Jupiter is shown facing the viewer frontally with both his arms and legs spread broadly across the canvas, while the color of his dress and flesh echos that of the marble at his feet. In contrast, Thetis is rendered in sensuous curves and portrayed in supplication to the mercy of a cruel god who holds the fate of her son in his hands. Thetis' right hand falls on Jupiter's hip with a suggestion of erotic caress, while the dark green of her dress accents the dread and foreboding of the bare landscape behind. Her clothing is drawn up against her lower hip, and seems about to fall off. The focal point of the work is Thetis' left hand extended vertically upright as she attempts to stroke the beard of the god.
Jupiter's pose is closely based on that of the famous chryselephantine sculpture, the Statue of Zeus at Olympia (Zeus being Jupiter's Greek equivalent), one of the Seven Wonders of the Ancient World. This was made by the Greek sculptor of the Classical period, Phidias, circa 432 BC and destroyed in Antiquity, but its pose is known from coins and small replicas. Here the pose is reversed right to left, and the arm to the viewer's right is higher than in the original, which held out a statue of Nike.
