The horsemen are immediately preceded in the procession by the chariot-groups. Carrey draws eight chariots, of which four partially survive and four are totally lost. On the other hand, a part remains of two groups (slab xxix.), of which there is no trace in Carrey's drawings. These, therefore, must probably be placed in a break in the sequence of slabs indicated by Carrey. Originally there must have been not fewer than ten chariot groups. In each the charioteer is accompanied by an armed warrior; but here the armed figure is not like the apobates of the northern frieze in the act of stepping out of the chariot in motion, but stands either in the quadriga or (if it is not in motion) by its side. Therefore Michaelis supposes that, while the chariots on the north frieze have reference to that contest in which armed apobatae took a part, leaping off and on to the quadriga during the race, the chariots in the south frieze suggest the chariots of war, _harmata polemisteria_, in which an armed hoplite stood in the chariot by the side of the charioteer. Each chariot group, when complete, is seen to be accompanied by a marshal. [Rightnote: XXIV.] [Sidenote: 58.] Of the two figures in the chariot of slab xxiv., nothing now remains but part of the shield and left arm of the hoplite (No. 58), with a fold of drapery hanging from the arm. The upper part of the slab was wanting in the time of Carrey, but he gives the legs of the hoplite, who, like the corresponding figure in slab xxv., was standing by the wheel of the chariot, of which a small portion remains. This position shows that both these chariots were represented at the moment before they started. In the shield of No. 58 are two rivet holes for the attachment of a bronze handle. In the upper hole the metal still remains. Similar rivet holes occur in the shields of Nos. 61 and 66. Michaelis supplies the heads of the horses on this slab by a fragment which belongs to the cavalcade of horsemen. (See slab xxii., above.) The connection between slabs xxiv. and xxv. is proved by a fragment which has been added to the lower corner on the right of slab xxiv. since the work of Michaelis was published. This fragment, of which the original is at Athens, gives part of the wheel of the chariot of xxv. and the forefeet of the horses of xxiv.
