The block was removed by Elgin and is today in the British Museum. The theme represented is that of two young horsemen galloping their horses, one behind the other, toward the left. The second horse overlaps the first only slightly. The first rider (2) at the left is the only nude horseman and he has long hair that blows out behind him with the speed of the horse. Fastened at his neck with a brooch is his chlamys, which blows out behind him in a beautiful sequence of folds. With his right hand he holds the reins and he turns back so that his body is almost frontal and his head turned even more toward the figure behind him (3). His left arm is raised in a gesture not entirely clear, perhaps to adjust the stephane on his head, perhaps to give a signal to the next horseman. The youth (133) on block N XLVII makes a similar gesture. Horseman (3) wears a modelled cuirass over a short chiton, just as do figures (7) and (18), and he is shod in boots.
