Thrinacia (Greek Θρινακία; also Trinacria, or Thrinacie), mentione in book 12 of Homer's Odyssey, is the island home of Helios' cattle, guarded by his eldest daughter, Lampetia. It is said to have been Sicily since the name Thrinacia implies an island connected to the number three and Sicily has three corners. The fact that Sicily is often identified with the episode of the Cyclopes only serves to underscore the shaky footing any geographer is on when trying to identify Homer's locations.
