There were other motives to this change, and particularly (as we have attempted to show in a separate dissertation) motives of high political economy, suggested by the relative conditions of land and agriculture in Thrace and Asia Minor, by comparison with decaying Italy; but a paramount motive, we are satisfied, and the earliest motive, was the incurable Pagan bigotry of Rome. Paganism for Rome, it ought to have been remembered by historians, was a mere necessity of her Pagan origin. Paganism was the fatal dowry of Rome from her inauguration; not only she had once received a retaining fee on behalf of Paganism, in the mysterious _Ancile_, supposed to have fallen from heaven, but she actually preserved this bribe amongst her rarest jewels. She possessed a palladium, such a national amulet or talisman as many Grecian or Asiatic cities had once possessed--a _fatal_ guarantee to the prosperity of the state. Even the Sibylline books, whatever ravages they might be supposed by the intelligent to have sustained in a lapse of centuries, were popularly believed, in the latest period of the Western empire, to exist as so many charters of supremacy. Jupiter himself in Rome had put on a peculiar Roman physiognomy, which associated him with the destinies of the gigantic state. Above all, the solemn augury of the twelve vultures, so memorably passed downwards from the days of Romulus, through generations as yet uncertain of the event, and, therefore, chronologically incapable of participation in any fraud--an augury _always_ explained as promising twelve centuries of supremacy to Rome, from the year 748 or 750 B. C.--coöperated with the endless other Pagan superstitions in anchoring the whole Pantheon to the Capitol and Mount Palatine. So long as Rome had a worldly hope surviving, it was impossible for her to forget the Vestal Virgins, the College of Augurs, or the indispensable office and the _indefeasible_ privileges of the _Pontifex Maximus_, which (though Cardinal Baronius, in his great work, for many years sought to fight off the evidences for that fact, yet afterwards partially he confessed his error) actually availed--historically and _medallically_ can be demonstrated to have availed--for the temptation of Christian Cæsars into collusive adulteries with heathenism. Here, for instance, came an emperor that timidly recorded his scruples--feebly protested, but gave way at once as to an ugly necessity. There came another, more deeply religious, or constitutionally more bold, who fought long and strenuously against the compromise. "What! should he, the delegate of God, and the standard-bearer of the true religion, proclaim himself officially head of the false? No; that was too much for his conscience." But the fatal meshes of prescription, of superstitions ancient and gloomy, gathered around him; he heard that he was no perfect Cæsar without this office, and eventually the very same reason which had obliged Augustus not to suppress, but himself to assume, the tribunitian office, namely, that it was a popular mode of leaving democratic organs untouched, whilst he neutralized their democratic functions by absorbing them into his own, availed to overthrow all Christian scruples of conscience, even in the most Christian of the Cæsars, many years _after_ Constantine. The pious Theodosius found himself literally compelled to become a Pagan pontiff. A _bon mot_ [Footnote: "A _bon mot_."--This was built on the accident that a certain _Maximus_ stood in notorious circumstances of rivalship to the emperor [Theodosius]: and the bitterness of the jest took this turn— that if the emperor should persist in declining the office of _Pont. _Maximus_, in that case, "erit Pontifex Maximus;" that is, Maximus (the secret aspirant) shall be our Pontifex. _So_ the words sounded to those in the secret [_synetoisi_], whilst to others they seemed to have no meaning at all.] circulating amongst the people warned him that, if he left the cycle of imperial powers incomplete, if he suffered the galvanic battery to remain imperfect in its circuit of links, pretty soon he would tempt treason to show its head, and would even for the present find but an imperfect obedience. Reluctantly therefore the emperor gave way: and perhaps soothed his fretting conscience, by offering to heaven, as a penitential litany, that same petition which Naaman the Syrian offered to the prophet Elijah as a reason for a personal dispensation. Hardly more possible it was that a camel should go through the eye of a needle, than that a Roman senator should forswear those inveterate superstitions with which his own system of aristocracy had been riveted for better and worse. As soon would the Venetian senator, the gloomy "magnifico" of St.
