According to Widukind of Corvey (c. 975), there also existed a ceremony praying for the dead on 1 October in Saxony. But it was the day after All Saints' Day that Saint Odilo of Cluny chose when in the 11th century he instituted for all the monasteries dependent on the Abbey of Cluny an annual commemoration of all the faithful departed, to be observed with alms, prayers, and sacrifices for the relief of the suffering souls in purgatory. Odilo decreed that those requesting a Mass be offered for the departed should make an offering for the poor, thus linking almsgiving with fasting and prayer for the dead.
