Celtic Mythology

DELT the Wet was one of the nine cupbearers of the Túatha Dé Danann. During the run-up to the Second Battle of Mag Tuired on Samhain, he aided his brethren in concealing the twelve chief lochs and twelve chief rivers of Ireland from the Fomor giants and prevented them from finding water in them. 

The lochs were Lough Derg, Lough Luimnig, Lough Corrib, Lough Ree, Lough Mask, Strangford Lough, Belfast Lough, Lough Neagh, Lough Foyle, Lough Gara, Loughrea and Marlóch and the rivers were the Bush, the Boyne, the Bann, the Blackwater, the Lee, the Shannon, the Moy, the Sligo, the Erne, the Finn, the Liffey and the Suir.
