and other works. These are collected in the proscenium, and form an interesting exhibition, giving some idea of the former richness of the decoration. The upper part of the scena carried the roof above referred to. The beams were embedded in the solid masonry, and projected over the proscenium, the apertures formed in the walls to receive them being distinctly visible. This roof has evidently been one source of the destruction of the building, as the calcined and blackened appearance of the upper part of the walls shews that it has suffered from a great fire, the materials for which could only have been furnished by a wooden roof over the proscenium. The sketch (Fig. 6) shews some of the ranges of seats cut out of the rock,--those at the bottom being in a fair state of preservation; and also some of the built portion of one of the wings which united the great proscenium to the part of the auditorium cut out of the hill behind. In the Middle Ages this theatre, as often happened with the massive buildings of the Romans, was converted into a fortification, and formed an outwork of the castle erected by the Duke of Orange on the summit of the hill above. But so solid is its construction, being composed after the Roman manner of building, of great blocks carefully fitted together without cement, that it has been able to endure for at least 1500 years, almost without change, all the destructive influences both of man and the elements. Immediately adjoining the theatre on the west was a hippodrome, the outline of which is quite discernible from the high ground above. It seems to have run nearly the whole length of the present town, and remains of it may be traced at intervals among the houses. The length and comparative narrowness of the structure shew that it was intended for horse and chariot races, and not for gladiatorial combats and similar spectacles. Of this immense building almost the only architectural features now remaining are a large arch across one of the streets, locally, but erroneously, called a triumphal gate, and some portions of an arcade incorporated with the modern houses. Almost everywhere in Orange antique fragments are to be found, and several statues and mosaics have been discovered.
