Cath Maige Tuired: The Second Battle of Mag Tuired (Author: [unknown])

section 14

There was contention regarding the sovereignty of the men of Ireland between the Túatha Dé and their wives, since Núadu was not eligible for kingship after his hand had been cut off. They said that it would be appropriate for them to give the kingship to Bres the son of Elatha, to their own adopted son, and that giving him the kingship would knit the Fomorians' alliance with them, since his father Elatha mac Delbaith was king of the Fomoire.
