The Morrigan is a goddess of battle, strife, and fertility. Her name translates as either “Great Queen” or “Phantom Queen,” and both epithets are entirely appropriate for her. The Morrigan appears as both a single goddess and a trio of goddesses. The other deities who form the trio are Badb (“Crow”), and either Macha (also connotes “Crow”) or Nemain (“Frenzy”). The Morrigan frequently appears in the ornithological guise of a hooded crow. She is one of the Tuatha Dé Danann (“Tribe of the goddess Danu”) and she helped defeat the Firbolg at the First Battle of Mag Tuireadh and the Fomorians at the Second Battle of Mag Tuireadh.
She appeared to the hero Cu Chulainn (son of the god Lugh) and offered her love to him. When he failed to recognize her and rejected her, she told him that she would hinder him when he was in battle. When Cu Chulainn was eventually killed, she settled on his shoulder in the form of a crow. Cu’s misfortune was that he never recognized the feminine power of sovereignty that she offered to him.
