The Morrígan (“phantom queen”) or Mórrígan (“great queen”), also written as Morrígu or in the plural as Morrígna, and spelt Morríghan or Mór-ríoghain in Modern Irish, is a figure from Irish mythology who appears to have once been a goddess, although she is not explicitly referred to as such in the texts.
The Morrigan is a goddess of battle, strife, and fertility. She sometimes appears in the form of a crow, flying above the warriors, and in the Ulster cycle she also takes the form of an eel, a wolf and a cow. She is generally considered a war deity comparable with the Germanic Valkyries, although her association with cattle also suggests a role connected with fertility, wealth, and the land.
She is often depicted as a triple goddess,although membership of the triad varies; the most common combination is the Badb, Macha and Nemain, but other accounts name Fea, Anann, and others.
