In front of the temple are remains of a large altar of whitish limestone (III). On the east side of the court is the base of an equestrian statue (V), of the same material, which was afterwards veneered with marble; near it is a pedestal of a standing figure (VI), of masonry covered with stucco, and behind this is the small base of a fountain figure. Near the southeast corner is the entrance (IV) to a subterranean passageway which runs toward the south; it probably led to rooms of earlier houses which were preserved, when the area was filled up, for the use of the attendants of the temple. The temple itself, as the other edifices, religious and secular, of the first years of the Roman colony, must have been built of common materials and coated with stucco. Of the existing remains only the inner part of the podium (I, II on the Plan) can be assigned to it; a series of small blocks of tufa at the rear end is perhaps a remnant of the cornice which was carried around the upper edge of the podium. To the Pompeians of the Empire the modest structure of Republican days seemed unworthy of the tutelary divinity of their city. On the same podium they built a temple of marble. Of this are preserved the foundations of the door posts of the cella (Fig. 56 _a_) and the core of the pedestal (D) on which stood the statue of the divinity, besides some bits of the cella floor, which consisted of a border of white mosaic (_b_), a broad strip of pavement of small flags of colored marble (_c_), and an ornamental centre (_a_) now entirely destroyed. The only remains of the superstructure that can be identified are in a storeroom north of the temple of Apollo. They consist of fragments of large marble columns, nearly thirty-two inches in diameter, and of an entablature of corresponding dimensions.

First of all they enlarged the court by removing the old walls to the foundations, and constructed new outside walls (_a-b-c-d_), the corners of which form right angles. The wall on the north side, of reticulate work, can be distinguished in Fig. 55. That on the east side is also well preserved, but of that on the south side no trace remains. The deep foundation of the wall on the west side forms the farther wall of the present Museum, the roof of which very nearly represents the level of the floor of the ancient court. The colonnade was to be single on the north, double on the east and west sides. The principal entrance was at the northeast corner (K), with a smaller entrance (L) at the end of the narrow street south of the Basilica.
