Broteas was the leader of a group of homeless villagers. He led them to the cursed village of Parthus where he stole a golden chalice that was sacred to Hera. He claimed he wanted to sell the chalice to benefit the entire group but his comrades didn't believe him once he was exposed as the thief. When the other villagers were led by Hercules to the charmed city of Calydon Broteas was chased off into the Stymphalian Swamp.
