Antiquity of her recognition
Based on the evidence of place-names, such as the river Danube (Latin: Danuvius), Dniestr, Dniepr and Don, Danu may have been worshiped throughout the Celtic world. Indeed, the presence of a goddess named Danu in Hindu mythology, associated with water and mother of a race of Asuras called the Danavas, may indicate a very ancient Proto-Indo-European origin for this figure.
In mythology
As the mother of the gods, Danu has strong parallels with the Welsh literary figure (or goddess) Dôn, who is the mother figure of the medieval tales in the Mabinogion.
