Danu

Scholars reconstruct Danu as an ancestral or mother goddess whose name is the eponym for the Tuatha Dé Danann (Old Irish glossed as 'the peoples of the goddess Danu'). The supplied sources do not preserve an indigenous, narrative origin myth of Danu in medieval Irish texts; instead the reconstruction rests on the ethnonym and comparative linguistic and mythological arguments that place a figure named Danu as a matronal ancestor of that supernatural people. Comparative notes in the supplied material also connect the name to a wider Eurasian river/goddess motif (including an ancient Scythian word meaning 'river' and cognate goddess names in other traditions), but the supplied sources do not provide primary evidence of a continuous narrative linking those traditions to the Irish form.

No medieval Irish descriptions of Danu's physical appearance are provided in the supplied materials. Because the primary sources summarized do not include iconography or corporeal descriptions, modern images of Danu are the result of later reconstruction and comparative imagination rather than testimony in the supplied texts; the absence of descriptive data in the provided sources means any specific visualization is conjectural relative to the present notes.

The supplied material does not attribute specific powers, actions, or behaviors to Danu within the Irish tradition. The principal role recorded in the provided sources is a reconstructive one: Danu is identified as the mother goddess or eponymous ancestor of the Tuatha Dé Danann. Comparative entries in the same reference note that the name Danu is associated elsewhere (in broader Indo‑European and South/Southeast Asian contexts) with water or river goddesses (e.g., an Indo‑European water goddess, Danu as a Hindu primordial waters Asura, and Dewi Danu in Balinese Hinduism), but the supplied Irish‑specific material does not document explicit water‑control, fertility, or other operative powers for the Irish Danu and does not allow asserting those abilities for her in Irish sources.
