[Ir., fair, white; poet, seer].
Mythical early king of Leinster thought to have resided at Dún Ailinne, the largest ring-fort in Ireland. Although modern commentators do not describe Find File as historical, poetry is attributed to him and his name is cited in genealogies. Various texts portray him as the brother of Cairbre Nia Fer, king of Tara, and son of a Ros Ruadh, giving him the occasional patronymic of mac Rosa or mac Rossa Ruaid. In Táin Bó Cuailnge [Cattle Raid of Cooley], Medb tells her husband Ailill that she had been wooed by Find File. Some of his characterization apparently derives from the ancient Find, and he contributes some motifs to Fionn mac Cumhaill. Despite the similarity of their names (Fionn is Find or Finn in Old Irish) and the names of their residences (the Hill of Allen is Almu in Old Irish), they retain distinct identities in Irish-language contexts.
