 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 9th 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 " .
