Content:  In Irish mythology, Ériu (modern Éire ), daughter of Delbáeth and Ernmas of the Tuatha Dé Danann, was the eponymous matron goddess of Ireland. The English name for Ireland comes from the name Ériu and the Germanic (Old Norse or Old English) word land. Since Ériu is represented as goddess of Ireland, she is often interpreted as a modern-day personification of Ireland, although since the name Ériu is the Old Irish form of the word Ireland, her modern name is often modified to Éire or Erin to suit a modern form.
