Phineus tormented by the Harpies, pencil rough

Phineus's own blinding was variously attributed to the outrage against his sons,  his giving Phrixus directions on his journey,  or because he preferred long life to sight,  or, as reported in the Argonautica (thus the best known version), for revealing the future to mankind.  For this reason he was also tormented by the Harpies, who stole or defiled whatever food he had at hand or, according to the Catalogue of Women, drove Phineus himself to the corners of the world.  According to scholia on the Odyssey, when asked by Zeus if he preferred to die or lose sight as punishment for having his sons killed by their stepmother, Phineus chose the latter saying he rather never see the sun, and consequently it was the scorned Helios who sent the Harpies against him.  However the Harpies plagued him, deliverance from this curse motivated Phineus's involvement in the voyage of the Argo.
