Eriu

In Dal-Riada & Celtic mythology, Eriu was the personification of Ireland and mother of Bres by Prince Elatha. She was one of the Tuatha de Danann. The name "Ireland" comes from her name.

Along with her sisters (daughters of Dagda & Delbaeth), Fodla and Banba, she was part of an important triumvirate of goddesses. She was a Goddess of Sovereignty and the maiden/spiritual aspect of of the triplicity Goddesses with her two sisters. She was the third of the three to be approached and challenged by the Milesians. She fought long and fierce for Ireland, winning the battle but losing Ireland. In honor of her fight, the Milesians named Ireland for her.
