National Archaeological Museum, Athens, 215. 330-20 BCE. This relief slab is one of four that made up the revetment of a pedestal (only three survive), and was found at Mantineia, Arcadia. The pedestal either acted as a base for a statue group of the Delian trinity (Leto, Apollo, and Artemis) or as an altar. On this relief the musical agon between Apollo and Marsyas is depicted. Apollo sits at left with his kithara, listening to Marsyas, at right, playing his auloi. At centre is the Scythian who will punish Marsyas for loosing the agon by flaying him; his knife is held ready in his right hand.
