A busy procession of horsemen and chariots is shown, coming up behind elders, musicians, porters and oxen.
The selection of casts here is dominated by the procession of overlapping horsemen, with a few chariots in front. The solo horsemen are near-naked and unarmed, unlike the charioteers, indicating that they are ready for a peaceful ceremony not a battle. The relief is no more than seven centimetres deep.
The horses are rearing up as the cavalcade has to slow down approaching the walking figures in front; a cluster of bearded officials and three men carrying water jars. A man playing a pipe is just visible behind them. This is the slab shown in the picture
