This article describes the death of the famous medieval abbot, Aelred, from the Cistercian abbey of Rievaulx (England, Yorkshire) (1110-1167). Walter Daniel of Rievaulx, Aelred’s secretary and caretaker, was the only person who wrote about his death. Daniel was a very skillful monk, whose description of Aelred’s death constituted a last part of his writings about Aelred’s life.
