Ritumagus
Ritumagus in Gallia, a Mansio which is placed in the Anton. Itin. and in the Table on a road on the north side of the Seine from Rotomagus (Rouen) to Lutetia (Paris); and between Rotomagus and Petromantalum. The distance of Ritumagus from Rotomagus is viii. in the Table and ix. in the Itin., which distance fixes Ritumagus near Radepont, at the passage of the Andelle, a small stream which flows into the Seine.
