A king of Ulster in Tochmarc Étaíne[The Wooing of Étaín], whose unnamed wife gives birth to the mortal incarnation of Étaín. She drinks from a golden cup containing a fly, which is the transformed Étaín. Étar is described as the king of Inber Cichmaine, a place-name that occurs frequently on the map of early Ireland. The text indicates the non-existent kingdom of Echrad in north-east Ulster. This Étar appears to be identical with the king of the same name who fathers a divine Étaín in Togail Bruidne Da Derga[The Destruction of Da Derga's Hostel].
