Rhoetus
Rhoetus was a character mentioned by Ovid in Book V of his mock-epic Metamorphoses.
After Perseus rescues Andromeda from the sea monster, her betrothed Phineus, brother of her father, attacks Perseus, throwing a spear at him. Perseus, in turn, throws the spear back, but Phineus hides behind the altars, and the spear strikes Rhoetus.
