DIODO´RUM a town in Gallia, placed by the Antonine Itin. on the road from Rotomagus ( Rouen) to Lutetia (Paris). It lies between Durocasses ( Dreux) and Paris, 22 Gallic leagues from Dreux, and 15 from Paris.The place was on a stream, as we may infer from the termination dur;the first part of the name may be another form of Divo, as in Divodurum. Some geographers make the place Davron. D'Anville fixes on Jouarenear Pontchartrain.
