Boann

Boann or Boand (modern spelling: Bóinn) is the Irish mythology goddess of the River Boyne, a river in Leinster, Ireland. According to the Lebor Gabála Érenn she was the daughter of Delbáeth, son of Elada, of the Tuatha Dé Danann. Her husband is variously Nechtan, Elcmar or Nuada. Her lover is the Dagda, by whom she had her son, Aengus. In order to hide their affair, the Dagda made the sun stand still for nine months; therefore, Aengus was conceived, gestated and born in one day.
