The work on metal vases took on a new fullness: the artists competed among themselves with great virtuosity. At Panagyurishte (now in Bulgaria), skilfully sculpted gold vases have been found: on an amphora, two rearing centaurs form the handles. In Derveni, not far from Salonica, a tomb has provided a great krater with bronze volutes dating from approximately 320 BC and weighing 40 kilograms (Derveni krater).
