Frutolf’s work, which contains information about the First Crusade (1096-1099), particularly relating to the People’s Expeditions, was used as the basis for the chronicle of Ekkehard of Aura, who provided a continuation up to the year 1125, including extended descriptions of the First Crusade and the Crusade of 1101.
