Zetes and Calais Chasing Away the Harpies
When the Argonauts arrived in Thrace, they found King Phineus tormented by the Harpies, monstrous bird-women who stole and defiled his food. Zetes and Calais, the winged sons of the North Wind, pursued the creatures across the seas to the Strophades Islands. There, the goddess Iris intervened, sparing the Harpies in exchange for a vow that they would never plague Phineus again.
