In following the procession along the south side from west to east, we pursue one branch of the procession which corresponds in the main with that on the north side. The main difference is that on the south the victims consist of cows only, while on the north there are sheep as well as cows. It may therefore be the case that this side represents the Hecatomb offered by the Athenians themselves. All the victims are cows, in accordance with Greek ritual, which ordained the sacrifice of male animals to a God, and female animals to a Goddess. [Rightnote: I.] [Sidenote: 1-4.] The left-hand side of slab i. is still on the Parthenon; the right-hand portion, containing the figure, No. 4, was presented to the Museum by the late Mr. C. R. Cockerell. A marshal (No. 1) stands at the angle; the first horseman (No. 2) advances at a walk, thus conforming to the rule that the movement is always gentle at an angle of the frieze. The horsemen of this slab all wear chiton, chlamys, boots, and a leather cap with a flap (_katablema_) hanging over the nape of the neck. [Rightnote: II.] [Sidenote: 5-7.] [Rightnote: III.] [Sidenote: 8-9.] Slab ii. is cast from the original on the Parthenon, which is in a very mutilated condition (cf. No. 345, _16_). Of No. 7 nothing now remains on this slab, but a bit of his drapery, and on slab iii. his right foot and his horse's nose and forelegs. Slab iii. was complete on the left edge in the time of Stuart, who gives the head and forehand of the horse of No. 7. The horseman (No. 8) wears a chlamys only, which is cast back so as to show the entire right side of the body. This is the only figure on the south frieze who is so little clad. [Rightnote: IV.] [Sidenote: 10-12.] On slab iv., the greater part of which still remains on the Parthenon, are the remains of three figures (Nos. 10, 11, 12). On the right side are two fragments of this slab, brought away by Lord Elgin, one of which only is given by Michaelis. The other has been since discovered in the magazines of the Museum. [At this point it has been necessary to interrupt the sequence by placing slabs xiv., xv., xx. on the sides of the pilaster. These slabs are described below in their respective places.] [Rightnote: V.] [Sidenote: 12-14.] [Rightnote: VI.-IX.] [Sidenote: 15-25.] On slab v., No. 13 wears a close-fitting cuirass, but is bare-headed. Compare the figures 26-35, and the description of Theagenes in the passage of Heliodorus, quoted on p. 148. Slabs vi.-ix. contain unarmed Athenian horsemen, riding bare-headed and for the most part wearing chiton with double girdle and boots only. The head of the rider, No. 15, is unfinished. The horses at this part of the frieze have manes with a large forelock turned upwards. [Rightnote: X.-XIII.] [Sidenote: 26-37.] [Rightnote: XIV.-XVI.] [Sidenote: 38-43.]
