The oval middle part with three mythological figures was cut out, and later four corners were added to obtain a rectangular shape. However, we cannot say with certainity, what the original composition looked like. This intriguing mythological scene, bringing to mind a music lesson, was probably shown on the background of a landscape. Three gods of various age dominate over the whole composition. In the foreground Pan plays the syrinx. Above Marsyas looks out, holding his attribute - aulos. The right part of the painting is occupied by a graceful, ephebe-like youth with long blonde hair. Covered in a blue mantle, which he gathers with his left hand in a refined manner on his breast, while his right one he holds what is probably a lyre.It could be Daphnis, son of Hermes, who was taught music by Pan. It may be Apollo himself.
