The present level of the Forum is many feet lower than that of its immediate surroundings. During the three thousand years that separate us from the beginnings of the city the valleys have been gradually filling through the accumulation of debris of ruined buildings, the washings of earth from the surrounding hills, and various other means. Recently scholars have excavated nearly the whole Forum down to the earliest level, laying bare the lower parts of buildings, the earlier pavements, altars, a primeval cemetery, and many other objects. Nearly everything found has been identified and clothed in the historical imagination with the associations of the time when it had a purpose and a meaning. But the spot, once the abode of intense life, is now still; it seems the burial place of a dead society and government; state officials keep drowsy guard over the remains. Tourist and scholar walk undisturbed through this sepulcher of a mighty empire, their senses awakened to the ancient life only by the rush of waters through the subterranean Cloaca Maxima, and to the life of our day by the roses, geraniums, and wild Italian flowers that grow luxuriantly wherever a bit of soil is left. THE ARCH OF TITUS Beyond the Forum and on the summit of the ridge known as the Velia is the Arch of Titus. We can read the inscription: SENATUS POPULUSQUE ROMANUS DIVO TITO DIVI VESPASIANI F. VESPASIANO AUGUSTO (The senate and people of Rome (dedicated this arch) to the deified Titus Vespasianus Augustus, son of the deified Vespasianus.) Consider this inscription. Both the Greeks and the Romans propitiated the spirits of the dead with sacrifice and prayer. The founder of a city or any specially great benefactor of the community they venerated after death as a hero, a being intermediate in dignity and power between man and the gods. [Illustration: THE COLOSSEUM FROM THE NORTH] It was with this idea that the senate by decree deified (more strictly, heroized) a deceased emperor who seemed to that body to have been a specially worthy ruler. Thus they had deified Vespasian, and after him his son and successor Titus. This arch, therefore, was dedicated by the senate and people to the memory of Emperor Titus after his death. A monument of the kind commemorated a victory so great as to entitle the general to a triumph,--a procession of the victorious commander and his army along the Sacred Way, past the Forum, and up the Capitol to the temple of Jupiter on the summit. The spoils of war were carried in the procession, while games and other festivities rejoiced the hearts of the populace.
