Parts of the harness can be seen on this slab, and also on slabs xiii., xix., xxi., xxiii. The general arrangement seems uniform, though there are differences of detail. The chariot pole ([Greek: rhymos]) passes from below the chariot between the horses. An upright pin ([Greek: hestôr]) passes through the pole (slabs xiii., xviii., xix., xxiii). At this point the yoke ([Greek: zygon]) was secured by a ring ([Greek: krikos]) and by the yoke-band ([Greek: zygodesmon]) (Hom. _Il._ xxiv.). The near end of the yoke, foreshortened and turned back, is visible on slabs xviii., xix., xxi., xxiii. On slabs xix., xxi. the yoke appears to be kept in position by a piece of metal passing from the top of the pin to the pole, which may, perhaps, serve instead of the ring. On slab xix. there appears to be a loop of a leather thong on each side of the piece described. This may be a part of the yoke-band. The reins were usually guided by two rings attached to the yoke or to the pole, but these do not appear to be shown on the frieze. It is easy to see on slabs xviii., xix., xxi., that the yoke was only fixed to the two middle horses, the outer pair being attached by traces. [Illustration: Fig. 12.--North Frieze, slab xix. (46. 47.)] [Rightnote: XIX.] The next slab (xix.) is a cast from the original at Athens, which is broken away on the right, so that all that remains of the charioteer (No. 47) is his right hand. At the side of the horses is a marshal (No. 46), who turns towards the chariot following on the right. Carrey's drawing supplies the upper part of this figure, and shows that he was holding up with his left hand the end of his mantle, apparently as a signal to the advancing procession. In fig. 12, slab xix. has been drawn in juxtaposition with the hitherto unplaced fragment No. 345, _12_. This slab was discovered in 1834. [Rightnote: XX.] Slab xx. is now lost, but a horse's head now at Athens (No. 345, _13_; Michaelis, pl. 12, xx.) may perhaps belong to it. [Rightnote: XXI.] Slab xxi. contains the bodies and hind quarters of the horses drawing the chariot seen on slab xxii. Between the charioteer (No. 48) and his horse is a fragment, showing the front of the chariot, and the tails of the horses, of which the original is at Athens, and which is not figured in Michaelis.
