Bk. IV. Ch. V. GATES, 339 line of this building and a boldness of profile that render it an ex- tremely pleasing example of the style adopted ; and though exhibiting many of the faults incidental to the design of the Colosseum, it pos- sesses all that repetition of parts and Gothic feeling of design which give such value to its dimensions, though these are far from being contemptible, the building being 115 ft. wide by 95 in height to the top of the wings. There probably were many similar gates of justice in the province, but all have perished, unless we except those at Autun just described. I am convinced that at that place there were originally such wings as these at Treves, and that the small church, the apse of which is seen on the right hand (Woodcut No. 217), stands upon the foundation of one of these. A slight excavation on the opposite side would settle this point at once. If it could be proved that these gateways at Autun -- r^-^^^S5 220. Bridge at Chamas. (From Laborde's " Monuments de la France.") had such lateral adjuncts, it would at once explain the use of the gallery over the arch, which otherwise looks so unmeaning, but would be intelligible as a passage coiniecting the two wings together. Another form also is that of an arch at the entrance of a bridge, generally bearing an inscription comniemorative of its building. Its purpose is thus closely connected with that of the arches before men- tioned, which commemorate the execution of roads. Most of the Q-reat bridges of Italy and Spain were so adorned ; bnt unfortunately they have been either used as fortifications in the Middle Ages, or removed in modern times to make room for the increased circulation of traffic. That built by Trajan on his noble bridge at Alcantara in Spain is well known ; and there exists a double-arched bridge at Saintes, in the south of France. The most elegant and most perfect specimen, however, of
