Note (return) — Chapter XVI
Reading edition
Both among the continental and Irish Celts those who sought hidden knowledge slept on graves, hoping to be inspired by the spirits of the dead.872 Legend told how, the full version of the Táin having been lost, Murgan the Filé sang an incantation over the grave of Fergus mac Roig. A cloud hid him for three days, and during that time the dead man appeared and recited the saga to him.
