Mythology tells us that when the invaders of Ireland known as the Miliseans landed at the Boyne, they made their way to Tara. Once there, they were advised by the Druids that they should return to their ships and sail off the shore to the length of nine waves. When they were on the sea a great storm arose which scattered their fleet. The commander of one of the ships was Donn. His ship was broken to pieces in the storm and he himself drowned along with twenty four of his comrades. He was buried on the Skellig Islands off the coast of Kerry.
He is the first of the new wave of invaders to meet his death in Ireland and, as such, he became elevated to the status of god of the dead. The place of his burial became known as Tech Donn - The house of Donn, and soon became identified with with the otherworld. The Celts were fascinated with tracing their ancestry back as far as they could and often they identified their earliest ancestors with the gods of their peoples. Hence, a belief arose that when they died they went to the house of their ancestor, the god of the otherworld.
It is interesting to note that the abode of Donn, on the Skellig Islands, is just a few miles from the traditional home of Mog Ruith at Valentia Island. As well as being geographical neighbours, both are closely associated with Samhain, when it can be said that Mog Ruith as sungod sojourns at the realm of the underworld, the abode of Donn.
Donn is seen as a retiring god who prefers the isolation of the bleak Skelligs and remains aloof from the other gods. His name means "brown" and he is associated with the shadowy realm of the dead. O'hOgain tells us that a ninth century text attributes a highly significant quotation to him "To me, to my house, you shall come after your death"
Many other sources say that the dead assemble at his house and describe deceased people travelling to and from here. Fishermen in the area were wont to hear strange boats passing to the island at night and the names of those who disembarked were called out.
