His parents were Lir and Penarddun and his wife was Fand. He ruled over the Blessed Isles as well as Mag Mell, the underworld.Manannan had many magical items. He gave Cormac his magic goblet of truth; he had a ship that did not need sails; he owned a cloak that granted him invisibility; a flaming helmet; and a sword that could never miss its target.

In the Isle of Man, Manannan mac Lir was known as Mannan. On Midsummer Eve, people offered green grass to Mannan-beg-mac-y-Leir and prayed for blessings in seafaring and fishing.
