Eriu- Celtic GodDeity"Sovereignty Goddess of Ireland"

The Meeting with the Milesians

The Lebor Gabála Érenn (Book of Invasions) records how the sons of Míl Espaine arrived at the shores of Ireland to claim the island from the Tuatha Dé Danann. As the Milesians marched inland toward Tara, they encountered three goddesses in succession, each at a significant point in the landscape. Ériu met them at the center of Ireland, at Uisneach, the sacred navel of the island where the provinces converge.

She greeted the newcomers and made them a promise: if they would name the island after her, their possession of it would endure. The poet Amergin mac Míled accepted her request and declared that the island would bear her name. From this moment, Ireland became Éire, the name derived from Ériu that persists in the modern Irish language and in the formal name of the Irish state.

Her two sisters, Banba and Fódla, made the same request at their own meeting-places, and Amergin granted each the honor of being an alternate poetic name for Ireland. All three names survive in Irish literary tradition, but it is Ériu's name that became the primary and ordinary designation, reflecting the centrality of her meeting-place and the primacy of her claim.

Sovereignty and the Land

Ériu belongs to the sovereignty goddess tradition in Irish mythology, in which the land itself is understood as a feminine divine figure whose favor the rightful king must win. The concept of the banais rígí (wedding feast of kingship) expresses this union: the king does not merely rule the land but marries it, and the goddess's acceptance or rejection determines whether the land flourishes or falls barren.

Ériu's marriage to Mac Gréine ("Son of the Sun"), one of the last kings of the Tuatha Dé Danann, places her within this framework. Her husband ruled Ireland jointly with his brothers Mac Cécht and Mac Cuill, each married to one of the three sovereignty sisters. When the Milesians defeated the Tuatha Dé Danann at the Battle of Tailtiu, these three kings fell, and sovereignty passed to the newcomers through the very act of naming that Ériu had secured.

The Dindshenchas (lore of places) and later medieval genealogical tracts identify Ériu as a daughter of Ernmas, linking her to the broader family of Tuatha Dé Danann goddesses that includes the Morrígan, Macha, and Badb. Her lineage thus connects the personification of the land to the war goddesses and the ancestral divine families of Irish mythological tradition.
