Gregory of Tours sends St. Lupicinus
inter illa Jurensis
deserti secreta, quae, inter Burgundiam Alamanniamque sita,
Aventicae adjacent civitati, in tom. i. p. 648.
M. de Watteville (Hist. de la Confederation Helvetique, tom. i. p. 9, 10) has accurately defined the Helvetian limits of the duchy of Alemannia, and the Transjurane Burgundy. They were commensurate with the dioceses of Constance and Avenche, or Lausanne, and are still discriminated in modern Switzerland by the use of the German or French language.
