There is a break in the composition at the beginning of slab x., and a change of subject is marked by the group not being carried across the joint. The figures (Nos. 26-37) on slabs x.-xiii. are evidently arranged in two ranks of six horsemen each, and are distinguished from most of the riders in the southern cavalcade by wearing a cuirass under which is a short chiton. Three of these figures (Nos. 33, 36, 37) have a cuirass consisting of a breastplate and backpiece, which are united at the sides by a strip of flexible scale armour. From the cuirass hang down the flaps, which protected the loins. These cuirasses also have shoulder straps. The riders, Nos. 26-36, wear the plain cuirass, rigid and close-fitting ([Greek: thôrax stadios]). All the riders in this part of the procession wear high boots with a flap turning over below the knee. They are all bareheaded except No. 36, who wears a cap or helmet with a flap behind; No. 33, who also wears a cap; and No. 35, who has a diadem over which must have been a metallic wreath, as there are four holes for its attachment on the crown of the head. A chlamys hangs from the left arm of Nos. 26, 27, 28. Slab xiv., which is a cast from the original at Athens, and slab xv. are now exhibited on the pilaster. Slab xvi., which is also a cast from the original at Athens, is in its place. Slab xiv. contains the head of the horse of No. 37. In front of it is a space marking a division, and another body of six horsemen (Nos. 38-43). These appear to be uniformly dressed in helmet, chiton without cuirass, and boots, and, although the positions of xv., xvi. are conjectural, the sequence proposed seems highly probable. In front of No. 43 there is a space similar to that between Nos. 37, 38. On the right side of xvi. is the outline of a horse's crupper, and floating above it in the air appears to be the long end of a mantle of skin such as is worn by No. 14 in the west frieze; behind No. 44 appears to be part of a garment of the same texture, the outline of which is seen above the horse's hind quarter. It is, however, doubtful whether xvi. and xvii. joined each other. Perhaps between them was a slab in which the horsemen wore similar mantles of skin. From this point the military order of the procession becomes less marked, or is obscured by the defective state of the marble. There is also more variety in the costumes of the riders. [Rightnote: XVII.] [Sidenote: 45*.] Slab xvii. is a cast from the original at Athens. Since the publication of the work of Michaelis, two fragments have been adjusted on the right, which prove the connection of the slab with No. xviii. by supplying the hind quarters of a horse of which the rest has been in xviii. These two fragments, which were unknown to Michaelis, also supply the forehand of another horse and the body of the rider (No. 45*) from the waist to below the knee (see fig. 14).
