In Manx mythology, the island was ruled by Manannán mac Lir, a Celtic sea god, who would draw his misty cloak around the island to protect it from invaders. One of the principal theories about the origin of the name Mann is that it is named after Manannan.
In the Manx tradition of folklore, there are many stories of mythical creatures and characters. These include the Buggane, a malevolent spirit who according to legend blew the roof off St Trinian's Church in a fit of rage; the Fenodyree; the Glashtyn; and the Moddey Dhoo, aghostly black dog who wandered the walls and corridors of Peel Castle.
The Isle of Man is also said to be home to fairies, known locally as the little folk or themselves. There is a famous Fairy Bridge and it is said to be bad luck if one fails to wish the fairies good morning or afternoon when passing over it. It used to be a tradition to leave a coin on the bridge to ensure good luck. Other types of fairies are the Mi'raj and the Arkan Sonney.
An old Irish story tells how Lough Neagh was formed when Ireland's legendary giant
Fionn mac Cumhaill (commonly anglicised to Finn McCool) ripped up a portion of the land and tossed it at a Scottish rival. He missed, and the chunk of earth landed in the Irish Sea, thus creating the island.
