Manannan

Manannán or Manann (Old Irish Manandán), also known as Manannán mac Lir (Mac Lir meaning "son of the sea"), is a sea deity in Irish mythology. He is affiliated with both the Tuatha Dé Danann and the Fomorians. In the tales, he is said to own a boat named Scuabtuinne ("Wave Sweeper"), a sea-borne chariot drawn by the horse Enbarr, a powerful sword named Fragarach ("The Answerer"), and a cloak of invisibility (féth fíada). He is seen as the guardian of the Otherworld and one who ferries souls to the afterlife. Manannán is furthermore identified with the trickster figure Bodach an Chóta Lachtna ("the churl in the drab coat").

Manannán appears also in Scottish and Manx legend, and some sources say the Isle of Man (Manainn) is named after him, while others say he is named after the island. He is cognate with the Welsh figure Manawydan fab Llŷr.

Manannán is also known as Oirbsiu or Oirbsen, from which Lough Corrib takes its name.

His name is spelt Manandán in Old Irish, Manannán in modern Irish and Scottish Gaelic, and Mannan in Manx Gaelic. He is also given two surnames. The most common is Mac Lir, which may mean "son of the sea" or "son of Ler". It has been suggested that Ler was a sea god whose role was taken over by Manannán. The other is Mac Alloit or Mac Alloid. Allot or Allod may be another name for Ler.
