W.J. Gruffydd's book "Rhiannon" (1953) was an attempt to reconstruct the original story. It is mainly focused on the relationship between the males in the story, and rearranges the story elements too liberally for other scholars' preference, though his research is otherwise detailed and helpful. Patrick Ford suggests that the Third Branch "preserves the detritus of a myth wherein the Sea God mated with the Horse Goddess." He suggests "the mythic significance may well have been understood in a general way by an eleventh century audience." Similar euhemerisms of pre-Christian deities can be found in other medieval Celtic literature, when Christian scribes and redactors reworked older deities as more acceptable giants, heroes or saints. In the "Táin Bó Cúailnge", Macha and The Morrígan similarly appear as larger-than-life figures, yet never described as goddesses.
