Goddess of the river Boyne, mother of Angus Mac Og by the Dagda.

Once there was a well chaped by nine magick hazel trees. These trees bore crimson nuts which gave knowledge of everything in the world. Divine salmon lived in the well and ate the nuts. No one, not even the high gods, were allowed to go near the well. But Boann went anyway. The well water rose to drive her away, but they never returned to the well. Instead they became the River Boyne and the salmon became the inhabitants of the river.

Other Celtic river Giddess: Siannan (Shannon), Sabrina (Severn, Sequana Seine), Deva (Dee), Clota (Clyde), Verbeia (Wharfe), Brigantia (Braint, Brent).

Healing.
