The last slab of the east side, BM 529 (Fig. 12, Pl. 45), restores a sense of ordered warfare, and the fortunes of the Greeks improve. One each of the armed (BM 529:2) and unarmed Greeks (529:4) is victorious over a centaur. The north portion of the frieze (Fig. 13), like that of the south that faces it, depicts the most important part of the action and is segregated from the rest of its subject by its compositional unity. The compositional patterns on both the north and south conform to the architectural forms below the frieze. On the three slabs at the south, groups balance one another in axial symmetry around the prominent central figure of Herakles, who stands above the Corinthian column. The four slabs on the north divide into two pain; the movement of the figures is largely centrifugal, so that the formal and narrative void at the center of the frieze echoes the architectural void of the doorway below. This centrifugal design brings to a halt the right-to-left movement of the spectator around the cella at the point where the frieze ends and he leaves the temple.
