Thrinicia

Thrinicia, mentioned in Homer's Odyssey, is the island home of Helios' cattle, is said to have been Sicily since the name Thrinicia implies an island connected to the number 3 and Sicily has three corners. However, Sicily is huge by ancient Greek standards and so its three corners are only noticable on the map, not at sea, and it is more likely that the name Thrinicia would have come about because sailors could use it to easily identify an island as they could see it.

The fact that Sicily is the often identified with the episode of the Cyclopes, only serves to underline the shaky footing any geographer is on when trying to identify Homer's locations.
