At the close of the second century after the birth of Christ the Christian community at Rome still saw no human prospect of that spiritual mastery of the world which they trusted some day to attain. They lived, for the most part, in the Transtiberina, the last and least reputable section of the great city, beyond the shelter of its walls. In that squalid and crowded district between the Janiculus and the Tiber dwelt the fishers and tanners and other poor workers; and the Jews, and others who shunned the light, found refuge among their lowly tenements. Near that early ghetto, from which they had issued, most of the Christians lingered. Still they were a small community, and still the might of Rome bade them crouch trembling at the gates, lost among the tombs and gardens of the Vatican or the dense poverty at the foot of the Janiculus. Across the river they would see, above the fringe of wharves and warehouses, the spreading line of the Roman people's palaces, from the Theatre of Pompey to the Great Circus: perhaps they would hear the roar of the lions which might at any time taste Christian flesh. Beyond these was the seething popular quarter of the Velabrum, sending up to heaven at night a confused murmur and a blaze of light at which the Christians would cross themselves; and on either side of the Velabrum, the stern guardians of its superstition, were the hills which bore the gold-roofed temple of Jupiter and the marble city of the Cæsars. More than one hundred and fifty years had passed since the death of Christ, yet his followers waited without the gates, little heeded by the million citizens of Rome. The old gods were dying, it is true. In many a cool _atrium_ there must have been some such discussion about the successor of Jupiter as has been finely imagined by Anatole France; but assuredly not the weirdest of the Syrian visionaries who abounded would have said that, in a few centuries, those neglected fields beside the Neronian Circus at the foot of the Vatican would become the centre of the world, and that men and women would come from the farthest limits of the Empire to kiss the bones of those obscure Christians. Men talked of the progress of the cult of Mithra, which spread even to distant Eboracum, or the success of the priests of Isis or of Cybele, but few thought about the priests of Christ. Earlier in the century, Pliny had written to court to say that he had found, spreading over his province, a sect named the Christians, whose beliefs seemed to him "an immoderate superstition"; though they had, he said, under pressure, abandoned their God in crowds; and he had little doubt that he would extinguish the sect. Few even of the Christians can have imagined that within two centuries their cross would be raised above the proudest monuments of Rome, and that the eagles of Jove and the rams of Mithra would lie in the dust.
