A visitor to this city of the Caesars must have been almost bewildered by what he saw. As he passes through the town great buildings meet his glance on every side, their gilded tiles and white marble walls glistening in the sun and clear atmosphere. Crowds jostle him in the narrow paved roads. He crosses one Forum after another, six in all, and finally reaches the Campus Martius. He pauses upon the steps of temples and basilicas which seem on all sides to surround these busy centres of Roman life. Open spaces are crowded with trees and shrubs, fountains and statues. He can count thirty-six triumphal arches and eight bridges that span the yellow Tiber. He passes theatres and _stadia_ for races and games, columns and obelisks. Occasionally he comes across a giant building, a colossus even in that city of marvels, the amphitheatre of Vespasian or the _thermae_ of Diocletian, or an immense circus where 285,000 spectators are seated waiting for the chariot races to begin; he has noticed groups of charioteers in their distinctive colours, and heavy betting is going on. He has walked from one end of the city to the other sheltered from sun and rain, along covered porticoes, their pavements rich mosaics, and their length decorated throughout with a continuous series of statues and pictures. He has gazed upon the stupendous palaces of the Palatine, and has noticed the streams of people passing in and out of the city gates on their way to the suburbs which extend to Veii Tivoli and Ostia, or to the villas, parks and gardens, villages and farms, which cover the outskirts of Rome to a distance of 15 miles, amongst which great roads lined by marble tombs radiate outwards towards the hills. With the decay of this mighty city began the era of church building. The origin of the Christian basilica is still a matter of controversy, but the results of careful and recent research[1] go to confirm the view that it was modelled not upon its Pagan namesake the forensic basilica, but upon the private hall found in many of the dwellings of rich Romans of consular or senatorial rank which served for those domestic tribunals for the adjudication of family disputes sanctioned by Roman law. This conclusion has been overlooked from a mistaken belief that the first Christians were recruited from the slaves and poorer classes of the population, but it is now proved that noble Romans and even members of Imperial families early embraced Christianity, and it was more than probable that the domestic basilicas in their houses should be utilised as places of assembly by members of their faith, the gathering of a large body of persons being concealed during times of persecution, by the use of the many entrances common to the Roman house.
