XXVIII.5 Continuation of the same subject
The law of Gundebald subsisted for a long time among the Burgundians, concurrently with Roman law ; it was still in use there in the time of Louis the Debonaire ; Agobard’s letter leaves no doubt about that. Likewise, although the Edict of Pistres calls the land that had been occupied by the Visigoths the land of Roman law, the law of the Visigoths still subsisted there, which is proven by the Synod of Troyes held under Louis the Stammerer in 878, which is to say fourteen years after the Edict of Pistres.
Subsequently, the Gothic and Burgundian laws perished even in their own lands, through general causes that made the personal laws of the barbarian peoples disappear everywhere.
