Dein Isarae Rhodanus aquis advenis locupletior, vehit grandissimas naves, ventorum difflatu iactari saepius assuetas, finitisque intervallis quae ei natura praescripsit, spumeus Gallico mari concorporatur, per patulum sinum quem vocant Ad gradus, ab Arelate octavo decimo ferme lapide disparatum.
After this the Rhone, enriched by the tributary waters of the Isre, carries very large craft, which are frequently wont to be tossed by gales of wind, and having finished the bounds which nature has set for it, its foaming waters are mingled with the Gallic Sea through a broad bay which they call Ad Gradus at about the eighteenth milestone distant from Arles.
