Final answer:
The Argonauts rid King Phineus of the Harpies with the assistance of the Boreads, who chased the Harpies away to the Strophades Islands where they pledged to leave Phineus in peace.
Explanation:
In the story of Jason and the Argonauts, the Harpies were seen as tormentors of King Phineus of Thrace. This blind king had been given the gift of prophecy by Zeus, but he was later punished by the god for revealing too much of the divine will. The Harpies would snatch away his food and leave what was left in a filthy state, ensuring he could not eat.
The Argonauts arrive and see the plight of Phineus. Two of the Argonauts, the Boreads, who are the sons of Boreas, the North Wind, and could also fly, confronted the Harpies. During a chase, the Boreads were able to drive the Harpies away to the Strophades Islands where they pledged never to bother Phineus again.
In gratitude, Phineus helped the Argonauts by giving them advice on how to pass the perilous clashing rocks known as the Symplegades, which lay on their route towards the Golden Fleece.
The account of the Harpies and the Argonauts depicts the interconnectedness of mortals and gods as well as the theme of trials and aid in quests seen throughout Greek mythology.
