In addition to these works on astronomical timekeeping, he also wrote "De natura rerum", or "On the Nature of Things", modelled in part after the work of the same title by Isidore of Seville. His works were so influential that late in the ninth century Notker the Stammerer, a monk of the Monastery of St. Gall in Switzerland, wrote that "God, the orderer of natures, who raised the Sun from the East on the fourth day of Creation, in the sixth day of the world has made Bede rise from the West as a new Sun to illuminate the whole Earth".
