This exhibition shows objects found in underwater archaeology in the Rhône and on display in the Musée départemental Arles antique. These objects date from the period after 46 BC, when the Roman colony Arles was founded by Julius Caesar. Arles (Arelate) lay on the trade road from the Mediterranean to Geneva (Genava), a city ruled by the Romans since 122 B.C. and this exhibition maps the early romanisation of Geneva and its relations with Rome and the Greek world.
