Midir

Midir was the son of Dagda. He was often called Midir the Proud. Midir had a fairy palace in Sleive Callary.

Midir seemed to appear more frequently during the time of the Ulster and Fenian cycles than before the arrival of the Milesians.

The most important story he was involved in was when Midir appeared as the Danann husband of Etain, his second wife. His first wife's jealousy caused her to change Etain into a butterfly. Eventually, Etain became mortal and married the mortal king, Eochy. Midir tried to win her back, but Etain remained with Eochy. (See the story of Etain for the full story, in the Ulaid Cycle.)

In the Acallam na Senórach, Midir had three daughters, Doirenn, Aife and Aillbe. Midir married his three daughters to the three princes, the sons of Lugaid Menn (the Stammerer) – Ruide, Fiacha and Eochaid.
