Anecdotes
In the Lebor Gabála Érenn ("The Book of the Invasions of Ireland"), Ernmas is presented as the mother of the three great war goddesses: Badb, Macha, and Mórrígan. This female trio formed a kind of triple deity of war and sovereignty, able to terrify armies with their cries and omens.
According to the mythical genealogies, Ernmas was also the mother of three goddesses who gave their names to Ireland itself: Ériu, Banba, and Fódla. The island's modern name, "Éire", is said to derive precisely from Ériu, making Ernmas a kind of symbolic ancestor of the Irish nation.
Ernmas belongs to the Tuatha Dé Danann, the "people of the goddess Danu", a group of deities who, according to legend, landed in Ireland wrapped in a mysterious mist. Medieval texts describe them as masters of magic, the arts, and druidic knowledge.
According to some versions, Ernmas is said to have perished at the second Battle of Mag Tuired, the great mythical clash pitting the Tuatha Dé Danann against the Fomorians, chaotic and hostile beings. Her death illustrates that even deities were not spared the cycle of conflict in Irish mythology.
Her name, "Ernmas", is sometimes interpreted by scholars as evoking "death by iron" or a "slaying by weapons", which would echo the warlike nature of her most famous daughters.
