Ithacus, son of King Pterelaus of the Teleboans and Amphimede, and a descendant of Zeus. Originally from Cephallenia, Ithacus together with his brothers Neritus and Polyctor decided to leave their homeland to preserve their own way of life. They were drawn to a nearby island, choosing it as the perfect site for a new colony because of its towering mountains offered excellent natural protection. After establishing their settlement, the local geography was named in their honour: the island itself became Ithaca, named after Ithacus; the prominent peak nearby was named Mount Neritus, after Neritus; and a third landmark, Polyctorium, took its name from their brother, Polyctor. These brothers were also said to have made a basin of stone in Ithaca into which a spring ran.
