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 not yet 31, the work severely and pointedly contrasts the grandeur and might of a cloud-borne 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.
Hers is extra tiny as well, I wonder if they match the artist.
