There was once a priest named Phineas actually, he was only a legendary figure.

This Phineas was a man who was given the power to see everything by the gods. However, he became arrogant and was punished by the gods. They took away his eyesight and Zeus commanded the bird-like harpies to steal his food whenever someone gave Phineas food.

Eventually, the Argonauts, who needed Phineas's powers, which he still had, came to him. They chased away the harpies and Phineas told them of one of the dangers they had to face. I can presume that he died peacefuly afterwards.

He does make an appearence in The Heroes of Olympus, the sequel series to Percy Jackson and the Olympians. Here, the curse of losing food has been reversed and Phineas is an antagonist here. He treats the Harpies terribly and thankfully, is killed by Percy in a small gamble. (I won't go into detail over that)
