Works & Achievements
Ernmas gives birth to Badb, Macha and the Mórrígan, who together form the great triple deity of war and Irish sovereignty.
Mother of Ériu, Banba and Fódla, she is the origin of Ireland's three poetic names, of which “Éire” is still in use today.
As a member of the Tuatha Dé Danann, Ernmas takes part in the mythic cycle of conflicts that shape the divine conquest of Ireland.
Through her descendants, Ernmas links the fertility of the land, war and royal power: her daughters embody the legitimacy of kingship in Ireland.
Her central place in the female genealogies makes her a pivot of the Irish pantheon, connecting many goddesses to one another.
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.

Daily Life
Morning
As a mythological figure, Ernmas has no documented daily routine. We may imagine her, like the Tuatha Dé Danann, opening the day in an underground dwelling (sídhe) bathed in magical light, surrounded by her daughters.
Afternoon
The tales credit the Celtic deities with activities of feasting, counsel, and magical practice. Ernmas, mother and “witch,” would have watched over her lineage and passed on druidic knowledge.
Evening
In the evening, Celtic mythology evokes gatherings where poems and omens were recited. Her warrior daughters, for their part, were associated with nights of battle and with the cries that herald death.
Food
The Tuatha Dé Danann were fed by treasures of abundance such as the Dagda's cauldron and the ever-renewing pigs of Manannán. Their mythical “diet” symbolizes immortality and prosperity.
Clothing
We picture the Celtic goddesses dressed in long robes and cloaks fastened with brooches, adorned with torcs and gold bracelets, marks of their divine and noble status.
Housing
After their defeat, the Tuatha Dé Danann are said to have withdrawn into the sídhe — hills and burial mounds like Newgrange, enchanted underground worlds beyond the time of mortals.
