International audience During the excavation of a Roman villa 50 km West of Clermont-Ferrand (Auvergne, France) was found a fountain mouth in form of a dolphin flanked by shells and marine monsters. Worked in the local volcanic stone, this sculpture gives a new evidence on an original workshop whose models are to be searched in other stone sculptures, but also in mosaics and paintings. The basin could be dated to the second century AD
