founded a monastery and maintained strong connections. The name Nivelles either derives from the Germanic *Niuwa-alha, meaning new sanctuary, or from a Celtic toponym. According to this theory, the name Nibelung came to be attached to the Burgundian royal house after the Kingdom of Burgundy in southern France was absorbed into the Frankish kingdom in 613 and came under the rule of the Frankish Nibelungids. Rejecting a Burgundian origin for the name, Gillespie further notes that Gunther is recorded in Old English as Gūðhere, but is referred to as a Burgundian rather than a Nibelung, a name which is unattested in Old English. Referring to a Burgundian clan Ursula Dronke and Helmmut Rosenfeld argue that the name Nibelung originally referred to a Burgundian clan. They note the existence of several place names in Savoy, the location of the French kingdom of Burgundy, which can be derived from a reconstructed Nibilungos, including Neblens, Noblens, and Neublans. Dronke argues that after the resettlement of the Burgundians from the Rhine to the Kingdom of Burgundy in 411, the clan name Nibelung was transferred to the Burgundian royal dynasty of the Gibichings (Old Norse Gjúkingar). It was then afterwards adopted by the Franks, who came to identify the Gibichungs as Franks as well, as in the Waltharius. Rosenfeld, on the other hand, argues that the Burgundian clan name Nibelung was adopted by the Nibelungid cadet branch of the Frankish Pippinid dynasty once Charles Martell's brother Childebrand I and his descendants came to rule the former Burgundian kingdom as counts. The royal name Gibichung was then replaced in the heroic tradition with Nibelung in order to connect this Frankish cadet branch to the Burgundian royal dynasty. Dronke subscribes to the traditional scholarly derivation of the name Nibelung from nibel or nebel, meaning cloud or darkness. She notes that other Burgundian clan names are recorded with similar associations: Wulkingos, from wolkan, cloud; Dagilingos, deriving from day; Leuhtingos, deriving from light; and Sauilingos, deriving from sol, meaning sun. Rosenfeld derives the name instead from a name *Niwilo, which is a nickname for the name *Niuw-man (literally new-man). Nibelung would be the patronymic of this name, with the change from w to b showing Romance influence.
