A. H. Smith, A Catalogue of Sculpture in the Department of Greek and Roman Antiquities…
“ Of the pedimental groups, which appear to have once existed at each end of the temple, nothing now remains except the marks of the attachment of sculptures. Within the colonnade the two ends of the cella are adorned with a frieze of Parian marble, which is still in position. At the west, the length of the frieze is only equal to the width of the cella; at the east, the frieze is continued as far as the epistyle, or beams surmounting the colonnade.The west frieze is about 25 feet long; casts of 16 feet 4 inches are in the British Museum. ”
