In the Mythological Cycle of early Irish literature, Midir (Old Irish), Midhir (Modern Irish) or Mider was a son of the Dagda of the Tuatha Dé Danann. After the Tuatha Dé were defeated by the Milesians, he lived in the sidh of Brí Léith (believed to be Ardagh Hill, Co. Longford). The name Midir may come from the old Irish word for a judge, midithir.[1]
