This theory of a bodily immortality is supported by the Irish sagas, in which ghosts, in our sense of the word, do not exist. The dead who return are not spectres, but are fully clothed upon with a body. Thus, when Cúchulainn returns at the command of S. Patrick, he is described exactly as if he were still in the flesh. "His hair was thick and black ... in his head his eye gleamed swift and grey.... Blacker than the side of a cooking spit each of his two brows, redder than ruby his lips." His clothes and weapons are fully described, while his chariot and horses are equally corporeal.[1160] Similar descriptions of the dead who return are not infrequent, e.g. that of Caoilte in the story of Mongan, whom every one believes to be a living warrior, and that of Fergus mac Roich, who reappeared in a beautiful form, adorned with brown hair and clad in his former splendour, and recited the lost story of the _Táin_.[1161] Thus the Irish Celts believed that in another world the spirit animated the members. This bodily existence is also suggested in Celtic versions of the "Dead Debtor" folk-tale cycle. Generally an animal in whose shape a dead man helps his benefactor is found in other European versions, but in the Celtic stories not an animal but the dead man himself appears as a living person in corporeal form.[1162] Equally substantial and corporeal, eating, drinking, lovemaking, and fighting are the divine folk of the _síd_ or of Elysium, or the gods as they are represented in the texts. To the Celts, gods, _síde_, and the dead, all alike had a bodily form, which, however, might become invisible, and in other ways differed from the earthly body.
