Vetus had conceived a vast design: he had in contemplation a canal, by which the waters of the Moselle and the-Arar were to be communicated, to the end that the Roman forces might be able, for the future, to enter the Rhone from the Mediterranean, and passing thence into the Arar, proceed through the new channel into the Moselle, and sail down the Rhine into the German Ocean. This plan was on a great scale:
Luzio Veterek Mosela eta Saona batu nahi zituen, bien artean ubidea eginez, halako eran non itsasoz eramandako merkantziak, gero Rodano eta Saona eta ubidean zehar, Mosela ibaitik Rhenora eta handik ozeanora irten zitezen eta, lehor-bideetako eragozpenak kendurik, Mendebaldeko eta Iparreko kosta arteko nabigazioa posible izan zedin.
