Rectangular base. The cavities on the top surface were probably to receive a statue dedicated to the gods by a victorious athlete in a chariot race. In the front of the base there is a depiction of a tripod at the left (the big bronze vase, which served as a prize in athletic contests). Next to it, there is a four-horse chariot with galloping horses, depicted with a charioteer, who is probably the Goddess Nike (the personification of victory).
