Isaccea
Isaccea in Romania, where the Danube begins to divide into the arms of its delta, is the Novioduni of the map. It was the base of the Second Legion Herculia, later of the First Legion Iovia, and here, as the Roman historian Ammianus records, the emperor Valens built his bridge of boats across the Danube to march against the Goths. The name is Celtic, the new fort, a notable trace of Celts this far east. The map gives forty-one miles on to Salsovia; the Roman register of routes divides that stretch at Aegyssus, today Tulcea.
