Harpy, in Greco-Roman classical mythology, a fabulous creature, probably a wind spirit. The presence of harpies as tomb figures, however, makes it possible that they were also conceived of as ghosts. In Homer’s Odyssey they were winds that carried people away. Elsewhere, they were sometimes connected with the powers of the underworld. Homer mentions one Harpy called Podarge (Swiftfoot). Hesiod mentions two, Aello and Okypete (Stormswift and Swiftwing).
These early Harpies were in no way disgusting. Later, however, especially in the legend of Jason and the Argonauts, they were represented as birds with the faces of women, horribly foul and loathsome. They were sent to punish the Thracian king Phineus for his ill-treatment of his children; the Harpies snatched the food from his table and left a disgusting smell. Calais and Zetes, the sons of Boreas, finally delivered him. Virgil imitated the episode in the Aeneid; he called the chief Harpy Celaeno (Dark).
