Thrinacia (Homeric Greek Θρινακία Thrinakíā, from θρῖναξ "trident"; English pronunciation /θrɪˈneɪʃə, θraɪ-/) is the island home of the Cattle of Helios in Book XII of Homer's Odyssey, guarded by Helios' daughters Lampetia and Phaethusa, born to him by Neaera. Homeric Thrinacia was later identified with Sicily, and its name re-interpreted as Trinakria (Τρινακρία, from τρεῖς and ἄκραι, as "[island] with three headlands"). But Homeric Thrinacia is also associated with Malta, and Sicily is instead also identified with the episode of the Cyclops Polyphemus, son of Poseidon.
