had gift of prophesy from Apollo, but he abused it by revealing too much in his prophesies; Zeus took offense to this and punishes him with blindness and sends the Harpies to torture him; asks Jason for help with the Harpies, and the Boreads (Zetes and Calais) go after them because an oracle was given that says that "two sons of the North Wind" would help him; Jason asks him why he received his punishment, and Phineus swears that they "will not incur the wrath of heaven by helping him"; Argonauts trap the Harpies using food, and then chase after them; after the Harpies are gone, he baths to get rid of the Harpies' stench and eats a full meal; gives prophesy to the Argonauts (limited information) and tells them that they will come to the Cyanean Rocks (send a dove through first), the river Acheron (entrance to Underworld), the Amazons, and Colchis (where the fleece is; tells them to look for river Phasis, and on one side of river will be Aea and on the other side will be a tree in the grove of Ares guarded by a serpent); Phineus after being asked if they will return safely tells them they will return through a different route
