mac Der-Ilei, King of the Picts, sought authoritative advice from Abbot Ceolfrid on the reform of paschal cycles with a view to harmonising the celebration of Easter within his kingdom. By 716 both the Picts and the Columban clergy of Iona had adopted the pascha catholica. Final days Ceolfrid apparently knew that he was coming to the end of his life, and so he resigned his post and was succeeded by Hwaetberht. He then set sail for Rome with the intent of delivering the Codex Amiatinus Bible to Pope Gregory II. He made it as far as Langres in Burgundy, where he died on 29 September 716 and was buried.
