Son of the Irish sea-god Lir, magician with strange possessions. His magical boat Ocean-sweeper, steered by the wishes of its occupant; his horse Aonban, able to travel on sea or land; and his sword Fragarach, a match for any mail, all were brought by Lugh from "The Land of the Living" (i.e., fairyland).
As lord of the sea he was the Irish Charon, and his color-changing cloak would flap as he marched around the camp of hostile force invading Ireland. He is comparable with the Cymric Manawiddan and resembles the Hellenic Proteus.
