Note 211 — Chapter IV · CAMPAIGN AGAINST ARIOVISTUS. (Year of Rome 696.) (Book I. of the “Commentaries.”)
Reading edition
The “Commentaries” give here the erroneous number DC: the breadth of the isthmus which the Doubs forms at Besançon cannot have undergone any sensible variation; it is at present 480 mètres, or 1,620 Roman feet. The copyists have, no doubt, omitted an M before DC.
