Harpy

Classical sources present variant genealogies. Hesiod names the Harpyiai as daughters of Thaumas and the Oceanid Electra and groups them with other storm/sea-related figures (making them kin to the messenger Iris). Other authors and traditions offer alternate parentages linking them to sea or monstrous figures (e.g., Pontus, Gaea, Poseidon, or Typhon/Typhoeus), reflecting multiple local and literary traditions that situate harpies among wind- and chthonic-related beings.

Descriptions vary across classical authors and periods. Early portrayals (e.g., Hesiodic tradition as transmitted in later summaries) may present them as lovely-haired winged maidens; later Roman and Hellenistic-era writers emphasize a grotesque composite: bird-bodied with the heads or faces of maidens, pale and emaciated from hunger, long taloned legs or hands, and sometimes described as 'human-vultures.' Hyginus, for example, records a hybrid anatomy with feathers, cocks' heads, wings, human arms, great claws, and human female breasts and bellies. Iconography and literary taste produce a spectrum from attractive winged women to repulsive, taloned snatchers.

Classical sources attribute to harpies swift flight and a nature as personified storm-winds; they 'keep pace with the blowing winds.' Their characteristic actions are seizing and snatching (their name is glossed as 'snatchers' or 'swift robbers'), stealing or defiling food, abducting and tormenting individuals, and acting as instruments of divine retribution — described as 'the hounds of mighty Zeus' or 'ministers of the Thunderer' who may carry evildoers to the Erinyes or to Tartarus. Accounts emphasize speed, aerial mobility, and the power to make sustenance unfit by foul contamination or to remove people suddenly from the human realm.
