The temple consists only of a single cella, opening to the east, but has four columns at each end (_tetrastyle amphiprostyle_). It stood on a podium of three steps. The exterior was surrounded by a small frieze, 1 ft. 5-1/2 in. high, and measuring 26 ft. on its long sides, and 17 ft. 2 in. at the ends. The annexed cut (fig. 20) shows the plan of the temple. The arrangement of the slabs of the frieze has been most fully discussed by Ross, but is still uncertain in parts. The west frieze, according to Ross, consisted of the two slabs, Nos. 421, 422, in the Elgin Collection, and the return faces of two slabs of the north and south sides. Each return measures 1 ft. 7 in. The slabs, Nos. 421, 422, measure respectively 6 ft. 8-1/2 in., and 6 ft. 7-3/4 in. The total length, 16 ft. 6-1/4 in., is thus nearly equal to the estimated length of the side. The distribution of the slabs belonging to the long sides is doubtful. No. 425, cast from a corner stone, certainly belongs to the south side. Ross assigns No. 423 to the south side, No. 424 to the north side, on the hypothesis that the mounted horsemen on the same side proceed in the same direction. Kekulé (_Die Balustrade_, ed. 1869, p. 17) places them both on the south side, in an order more probable than that suggested by Hawkins (_Mus. Marbles_, ix., p. 29). The east side consisted of two slabs and two returns arranged similarly to those of the west. [Illustration: Fig. 20.--Plan of the Propylaea and Temple of Wingless Victory.] The subject of the east side appears to be a council of Gods. The long sides each contained a battle between Greeks and a series of warriors, mounted and on foot, wearing Asiatic costumes and probably intended to represent Persians. The west side is generally taken to represent a battle of Greeks with Greeks. Several attempts have been made to show that historical battles are represented on the frieze. Overbeck suggests that the three sides on which there are combatants belong to one battle, and he conjectures the battle of Platæa (479 B.C.), when Greeks defeated the Persians and their Greek adherents. Other writers, perhaps with more probability, deny that any definite battle is intended, and hold that we see merely a generalised representation of Athenians, victorious alike over Greeks and Barbarians.
