[Illustration: FIG. 23.--TEMPLE OP MARS THE AVENGER IN FORUM OF AUGUSTUS. (After Ripostelli.)] Emerging from this too narrow passage-way and proceeding a short distance, we enter that straight Flaminian Road which has been replaced by the modern Corso beginning at the Piazza Venezia. For the first part of its course it was also known as "Broadway." We are now in that more open part of Rome which lies outside the ancient wall, and which is commonly spoken of loosely as the Campus Martius. Here again, it is impossible to inspect all the various sights visible in the year 64. A few examples must suffice. As you walk along this straight thorough-fare--the commencement of the road which would eventually carry you to the North of Italy--you will find but few buildings of any note on your right. Lying to your left is a long and wide cloistered space which contains not only certain public offices and a pillared promenade, but also the richest shops in Rome, where are sold gold and silver work, objects of art, tapestries, and fine fabrics from Alexandria, Syria, and farther East. The place is, in fact, mainly a huge bazaar. Up the Flaminian Way beyond this enclosure we go under a triumphal arch erected by the late Emperor Claudius to record his conquest of Britain, where he subdued "eleven kings" without Roman loss. Keeping straight on we pass, this time on our right, another large enclosure surrounded by arcades, where is now the east side of the Piazza Colonna. In and about this locality are carried on not only promenades and saunterings but also various athletic exercises, including feats of horsemanship. Farther on still, and you will see to your left the Mausoleum of Augustus, rising some 220 feet into the air. Its base, coated with sculptured marble, contains one grand sepulchral chamber for Augustus himself, and fourteen smaller chambers for members of his family. Above this base towers a conical mound of earth planted with evergreen trees, and on the summit is a colossal statue of the first emperor. Close by is a paved space, where the bodies of the Caesars are cremated before their ashes are placed in the Mausoleum. From this spot a ready faith saw their immortal part carried up to heaven by the eagle, messenger of Jove.
