 These derive from Hellenistic monuments from Pergamon in Asia Minor showing Pergamene victories over the Gauls, and were all presumably commissioned for military commanders.The Portonaccio sarcophagus is the best known and most elaborate of the main Antonine group and shows both considerable similarities to the Great Ludovisi sarcophagus, and a considerable contrast in style and mood.The sarcophagus measures 1.53m in height and is made from Proconnesian marble, a medium characterized by dark gray stripes and a medium to coarse grain.
