The von Wartburg line (or Nantes-Épinal line) is the name commonly given to a language border highlighted by Walther von Wartburg in his 1939 study, Die Entstehung der romanischen Völker (The origins of the Romance peoples). This line enables a distinction between the northern and southern varieties of Gallo-Romance languages in the 9th century.[1] It was identified for the first time by Jakob Jud.[2]
According to Walther von Wartburg, this linguistic border is the result of Frankish settlement "north of the Loire River" and corresponds to the political and ethnic border that took form around the year 500 between the Frankish kingdom of Neustria in the north, and Aquitaine and Burgundy in the south. For other linguists, the Vulgar Latin spoken in northern Gaul was already different before the Franks' arrival.[6][7]
The von Wartburg starts from the mouth of the Loire, follows the river until the Sologne, before following the Loire again around Cosne-Cours-sur-Loire. From there, it continues north of the Morvan, leaving to the south a significant part of Burgundy and all of Franche-Comté before reaching the south of the Vosges.
