An alternate theory is that the name Llefelys is a compound, with the first element deriving from "Lleu" (the name is usually written as "Lleuelis" in the Red Book and White Book texts). Lleu is a major figure in the Fourth Branch of the Mabinogi, and is counterpart to the Irish mythological figure Lugh and the Gaulish god Lugus. Lludd is also probably related to an earlier pan-Celtic figure, represented by the Irish Nuada and the British Nodens, via the earlier form Nudd. Elements of "Lludd and Llefelys" bear some similarity with the Irish story of Nuada and Lugh, particularly the narrative "Cath Maige Tuired". Like Llefelys, Lugh is dispossessed while the kingdom (in this case Ireland) is ruled by his kinsman Nuada. Eventually the kingdom is beset by oppressors and both fertility and the food supply are affected, but Lugh returns to overcome the oppression with his vast skill and knowledge.
