The two cavaliers are followed by four _bigae_.

The first contains the principal personages of the composition, who sits back in his car, and shades himself with a parasol, the mark of high rank in the East, while his charioteer sits in front of him and holds the reins.

The second car has three occupants; the third two; and the fourth also two, one of whom leans back and converses with the footmen, who close the procession.

These form a group of three, and seem to be soldiers, since they bear shield and spear; but their costume, a loose robe wrapped round the form, is rather that of civilians.

The horses are lightly caparisoned, with little more than a head-stall and a collar; but they carry on their heads a conspicuous fan-like crest.[736] MM.
