Note 79 — LIFE OF CAIUS MARIUS.
George Long translation
This canal of Marius is mentioned by Strabo (p. 183) and other ancient writers. The eastern branch of the Rhone runs from Arelate (Arles) to the sea, and the canal of Marius probably commenced in this branch about twenty Roman miles below Arles (which did not then exist), and entered the sea between the mouth of this branch and Maritima, now Martigues. The length of the canal of Marius might be about twelve Roman miles. Marseilles is east of Martigues. (D'Anville. Notice de la Gaule Ancienne.)
