“The wind concentrated upon the ship where Donn the king was, and Donn was drowned at the Sandhills; whence Tech Duinn derives its name.” – Lebor Gabala Erenn, volume 5
There is some debate about whether the Irish have a God of the dead, but if they do its generally agreed that it would be Donn, a king of the Milesians who died at sea when the sons of Mil were trying to take Ireland. The place where he died, off the southwest coast of Ireland, was called Tech Duinn – Donn’s house. Tech Duinn became equated in folklore with the Otherworldly land of the dead and Donn with a primal ancestor and underworld God (Jones, 2004).
