DUMNISSUS a place in Gallia, on the road from Bingium ( Bingen) to Augusta Trevirorum ( Trier). The Table gives 16 Gallic leagues from Bingium to Dumnissus, and 8 from Dumnissus to Belginum. Ausonius, in his poem on the Mosella (5.1, &c.), mentions Dumnissus. After crossing the Nava ( Nahe), which joins the Rhine at Bingen, he speaks of passing through forests without tracks, where there was no sign of human cultivation; and he adds,— Praetereo arentem sitientibus undique terrisDumnissum, riguasque perenni fonte Tabernas.
The route of Ausonius from Bingenwas through the Hundsrück;but the site of Dumnissus is unknown. It is placed by some geographers at Denzen, near Kirschiberg. Belginum is supposed to be Belch, which in fact is the same name.
