Depicted on this block and on each of the next two (IX and X) are a pair of young horsemen (16-21) riding their steeds at a gallop. While the theme of the three blocks is the same, the difference in movement of the horses, the poses of the riders and the variety of their garments are of special interest. On block XI the horseman (21) has short curly hair and wears a short chiton. He bends his head concentrating on his hands with which he reins in tightly his prancing horse. Next to him, slightly to the left, the horse of rider (20) is partly hidden by the previous horse. The face of the horseman is unfortunately not preserved. He wears a chlamys, boots and Attic helmet with a crest that flows out behind. He rides his horse with body more erect than the others. He is one of the few horsemen whose other leg is shown in low relief hanging down behind the invisible side of the horse. The manes of the horses likewise are each different.
