A widely known harper of early Irish narrative; he is sometimes credited with the discovery of the harp, which he fashioned from a willow tree. Craiphtine is much associated with Labraid Loingsech, a legendary early invader of Ireland, and may be, as some commentators have suggested, a double for him. By playing his harp, Craiphtine cures Labraid Loingsech of dumbness; he also reveals the secret of Labraid's deformity of equine ears. Craiphtine's music lulls to sleep the garrison at Dind Ríg, allowing the capture of that fortress. Earlier Craiphtine sets music to the love-lay of Muiriath and carries it to Labraid in exile. Craiphtine's own wife, Scenb, is unfaithful.
