On the left is a Lapith, armed with shield and helmet, and wearing a chiton and sandals. He seems about to attack a Centaur, who rears to the right over the body of a Lapith, who has sunk down in a sitting position. Length, 2 feet 9 inches. _Mus. Marbles_, IX., pl. 20. Most of the figure of the seated Lapith, and the whole of the succeeding group of a Lapith and Centaur are not represented by casts in the Museum. CASTS OF THE EAST FRIEZE OF THE THESEION. On the east frieze is represented a battle in the presence of six seated deities arranged in two groups. In one part of the frieze the combatants are hurling vast rocks. Colonel Leake (_Topography of Athens_, 2nd ed. p. 504), supposed that Heracles and some of the gods are engaged in a battle with giants, while other deities, among them some who usually take a leading part in the fray, merely sit and watch. This, however, is a scheme of Gigantomachia to which no parallel can be adduced. [Illustration: Fig. 17.--The disposition of the East Frieze. (From Baumeister).] Brunn (_Sitzungsber. der k. bayer. Akad. Phil.-hist. Cl._, 1874, ii., p. 51), supposes the battle here represented to be that fought by the Athenians under Theseus against Eurystheus in defence of the Heracleidae. The scene on the left would thus represent the first rout of the troops of Eurystheus; then would come the storming of the Skironian pass by Theseus, where we might expect masses of rocks to be hurled on the assailants. The kneeling figure on the left of the central group (404, _4_), who is being bound would, according to Brunn, be Eurystheus, who was taken prisoner and put to death. The figure on the extreme right (404, _8_), who is stooping forward, Brunn supposes to be one of the victors erecting the boundary stone, which, according to the Attic legend, was set up by Theseus to mark the limits of the Peloponnese on the side of Attica. The theory is highly ingenious; but it demands a forced interpretation of the rocks to suppose them to be lining the two sides of a pass; and it overlooks the close parallelism with the east frieze of the Parthenon, where the two groups of gods must be supposed to form a single background to the scene. Also, the Skironian pass was a road between rocks and the sea. Moreover, the vast size of the rocks indicates a giant race, rather than a group of warriors who are reduced to using stones in an extremity.
