Pausanias Description of Greece 5.18.6

[6]
  On the third space of the chest are military scenes. The greater number of the figures are on foot, though there are some knights in two-horse chariots. About the soldiers one may infer that they are advancing to battle, but that they will recognize and greet each other. Two different accounts of them are given by the guides. Some have said that they are the Aetolians with Oxylus and the ancient Eleans, and that they are meeting in remembrance of their original descent and as a sign of their mutual good will. Others declare that the soldiers are meeting in battle, and that they are Pylians and Arcadians about to fight by the city Pheia and the river Iardanus.
