A little way south of the town, and on the level ground near the river, stands a remarkable though unfinished monument called the “needle” or “pyramid” (Fig. 3). The upper part consists of a tall and partly hollow square pyramid. The base is pierced with four arches, each flanked with two engaged columns, the capitals of which are only roughly blocked out. The Romans were in the habit of building thus, and executing the sculpture afterwards. The masonry is beautifully jointed and put together without cement; but the blocks have been cramped with iron, and the holes made for the purpose of extracting these cramps are unfortunately only too apparent here, as in so many other Roman edifices. There is no inscription or other indication of the purpose for which this monument was erected, but it has most probably been commemorative, and the name of Alexander Severus has been generally connected with it. Prosper Mérimée is of this opinion, and adds that “the interruption of the work might be explained by one of the revolutions so frequent in the Empire, which made men forget or denounce the memory of the person to whom divine honours had previously been paid.” [Illustration: FIG. 4. VIENNE RESTORED.] The existing remains show that Vienne must have been a town of great importance and splendour in Roman times. An attempt has been made by an architect of the district to exhibit in a drawing an illustration of what Vienne was like in the days of its glory, of which a reproduction is given in Fig. 4. This restoration, although to a great extent imaginary, at least serves to give some idea of the splendour of a Roman city. The next Roman edifices of importance in descending the Rhone are found at ORANGE, the ancient Arausio, the capital of the Cavares. It was taken by Cæsar, and became an important Roman colony. On approaching the town by the railway, one is struck by the appearance of an immense pile of building which rears itself high above all the other structures of the place, but is at too great a distance to allow its features to be distinguished. On closer inspection this turns out to be the proscenium wall of the famous Theatre of Orange. Everyone is acquainted with the general outline of the Roman amphitheatre, but the form of the theatre is probably not generally so well known. The seats were arranged in a similar manner to those of the amphitheatre, and were almost invariably cut out of the side of a hill, but they extended only round a semicircle. These constituted the auditorium, the diameter of the semicircle opposite them being occupied with a high wall which enclosed the theatre and formed the scena, in front of which was the stage where the actors appeared. This wall or scena was generally elaborately adorned with architectural features, including a profusion of marble columns with their entablatures, niches with statues, &c. Dressing-rooms and other apartments for the actors were either within the scena, or in spaces at the ends.
