Note 471 — Chapter X · (Year of Rome 702.) (Book VII. of the “Commentaries.”) REVOLT OF GAUL—CAPTURE OF VELLAUNODUNUM, GENABUM, AND NOVIODUNUM—SIEGES OF AVARICUM AND GERGOVIA—CAMPAIGN OF LABIENUS AGAINST THE PARISII—SIEGE OF ALESIA.

The ravine which descends to the Auron is still recognised at the present day, between the Portes Saint-Michel and Saint-Paul, by the sudden incline of the ground. Old plans of Bourges designate it by the name of the Vallée Saint-Paul. The opposite ravine, which runs towards the Porte Bourbonnoux, has disappeared under the successive fillings up composing the soil of the garden of the archbishop’s palace. The ridge of land forming the avenue cannot have been in Cæsar’s time more than 100 mètres broad. It has lost its primitive physiognomy, especially by the formation of the Place Sérancourt, in 1700, on a site the level of which did not then exceed that of the field of the present fair. The depression of the ground which existed before the wall is more visible; it has been filled-up during the different sieges of Bourges.
