Phineas, also spelt Phineus, was a figure in Greek myth.
The king of Thrace, he appears in the tale of Jason and the Argonauts. Granted with the gift of prophecy, Zeus later saw his gift to Phineas as dangerous, fearing he may reveal the plans of the gods. He had Phineas blinded and banished to an island with a feast. Before he could eat the food, the harpies ruined it and tormented Phineas until a pair of winged heroes called the Boreads scared them away.
