Among the Greek gods who came into Rome we saw the entrance in the middle of the third century before Christ of a pair of deities of the Lower World, Dis and Proserpina, and in connexion with the introduction the establishment of certain games called "secular" because they were to be repeated at the expiration of a century (saeculum). The initial celebration was in B.C. 249, one hundred years later with a slight delay they were celebrated again in B.C. 146, the next anniversary was omitted because it fell in the midst of the civil war between Caesar and Pompey, but now Augustus wished to celebrate them. There were chronological difficulties, but they did not prove insurmountable. An oracle was set in circulation, or one actually in circulation was made use of, wherein it was declared that a great cycle of four times one hundred and ten years had passed and that a new age was now beginning. The emperor, if not responsible for this oracle, was very willing to accept it. It was an essential part of his plan that all things should become new, and that with the new age should come a new spirit. This new saeculum must be ushered in by games which should be at once like and unlike those of past centuries. They were to be celebrated at least in part on the hallowed spot, the Tarentum in the Campus Martius, they were to extend through three nights like the old games, but the three days were to be added as well, and the deities worshipped in the night, while they were no longer the old gods of the Lower World, Dis and Proserpina, were at least mysterious deities of fate and fortune, while the gods of the day, Apollo and Artemis, Juppiter and Juno, were as new to the games as the day celebrations themselves were. But the equality of Apollo and Juppiter was expressed not merely in the parallelisation of Juppiter-Juno with Apollo-Diana. It was still more in evidence on the third and greatest day of the festival, when the procession of three times nine youths and three times nine maidens sang the song in honour of Apollo and Diana, which Horace wrote and which has been preserved to us among his writings, the Carmen Saeculare, and to which in addition the recently found inscription giving an account of the games bears witness in the words carmen composuit Q. Horatius Flaccus (C.I.L. vi. 32323). On this day the procession started from the Apollo temple on the Palatine, and went over to the Juppiter temple on the Capitoline, and then back again to Apollo on the Palatine, thus indicating not only the equality of Apollo and Juppiter but even the superiority of the former. A new age had indeed begun, an age in which the new associations of the Palatine and the glamour of imperialism were to overcome the more democratic associations of the Capitoline with its incorrigibly republican Juppiter. Greek gods which had hitherto in theory at least been subordinated to the gods of old Rome were now granted not only equality but superiority. The specific cult of Apollo, to be sure, did not always retain the exalted position to which Augustus had raised it, but even it never entirely lost its prominence, whereas the general idea of the supremacy of the imperial cult was now established for all time to come. But this secular celebration of Augustus is interesting aside from the relation of Juppiter and Apollo, for it affords another illustration of the skilful combination of new and old in the Augustan reorganisation. In form the festival is avowedly the old one, but in two respects at least it introduces a new element. In the first place participation in the old festival, as in all the old festivals, had been confined to Roman citizens. Others might look on, but they could not take part, nor were they the recipients of any of the blessings which were to follow. But now every free member of the community, with wife and child, might join in the celebration, and thus the note was struck which was to be the keynote of all that was best in the changes introduced by the empire whose "highest and most beautiful task," as Professor Mommsen puts it, "and the one which she fulfilled most perfectly, was gradually to reconcile and thus to put an end to the contrast between the ruling city and the subordinate communities, and thus to change the old Roman law of city-citizenship into a community of the state which embraced all the members of the empire." But even this was not all; under the guise of this restoration of an old republican institution a blow was struck at the very foundation of all republican institutions, namely the power of the Senate. It was par excellence Augustus's festival, arranged by him or by those to whom he had committed the details. The Senate had little or nothing to say about it and yet the control of such religious celebrations had hitherto formed an inalienable part of the Senate's power. Even in the procession itself the republican magistrates do not seem to have been officially present. It was thus no longer the Senate inviting the magistrates and the citizens in good and regular standing to perform a certain divine function, but it was the emperor inviting all the members of the community, citizens and non-citizens alike, to join with him in worshipping the gods of the new state.
A great part of Augustus's success was unquestionably due to a certain form of moral courage. For all his diplomacy and his desire to feel the pulse of the people he was never lacking in the courage of his own convictions. This can be seen nowhere better than in his attitude toward his adoptive father Julius Caesar. From the very beginning when he took upon himself, even at the cost of temporary impoverishment, the payment of Caesar's legacy, he was supremely true to the man whose successor he was, and this faithfulness is especially apparent in the field of religion. Here there are two cults, both relating to Julius Caesar, for which Augustus was largely responsible, that of the god Julius himself, and that of Mars the Avenger.
In consideration of what Caesar had already done for the reorganisation of the state, and in view of what he was planning to carry out, his death was a national calamity, but his influence might still be rescued and preserved by elevating him into the rank of the gods. For the accomplishment of this it was necessary that the Senate should act, for in the hands of the Senate alone lay the power to receive new gods into the state. Thus the god Julius was created and the word divus received a new meaning. With that logic which was characteristic of Roman religion from the very beginning, the elevation of Julius into the ranks of the greater and more individual gods went side by side with his exclusion from the ranks of the ordinary deified ancestors, so that thereafter at the funeral processions of the Julian family his wax mask was absent from the processions of ancestors to which he no longer belonged, but in the parade of the circus he was present, drawn in a waggon among the greater gods. Nothing was left undone to render his cult both conspicuous and permanent. A special priest (flamen) was appointed to look after it, and as the irony of fate would have it one of the first incumbents of this position was Marc Antony after his reconciliation with Augustus in B.C. 40. Then too a special festival day was given him among the religious holidays of the year. It was intended that this day should be July 13, his birthday, but as that day happened to be already devoted to an important celebration in connexion with the games of Apollo, the day preceding it, July 12, was chosen. But more was needed than a priest and a holiday, there must be a cult centre as well, a temple of the Divus Julius. The site of this temple was already given in the associations connected with Caesar's death. There could be but one place for it, and that was in the Forum near the Regia where his body had been carried to be burned. There the temple was built and dedicated August 18, B.C. 29. An altar had been erected on the spot where Caesar's body had been burned, and the new temple was so placed that the altar was included in its boundaries, occupying a niche in the centre of the front line of the substructure. The temple had the usual history of destruction and rebuilding in antiquity until in early Christian times it was used for secular purposes, and the eyesore of the pagan altar was removed by building a wall across the front, the diameter of the semicircular niche, and by roofing the altar over on a level with the existing platform. Thus the altar with its historical and religious associations was entirely lost sight of, and though the temple in its main outlines had long been excavated, the altar was not discovered until 1898, when the wall was broken through and the whole thing laid bare. Thus by the vote of the Senate, the appointment of a priest, the setting apart of a holy day in the year, and the building of a temple, the worship of the god Julius was established; but it was the general irresistible tendency toward emperor-worship which kept it alive and made it the model for a tremendous subsequent development. Augustus had accomplished his desire. Men were looking on Caesar as a success after all and not as a failure. The Di Manes of a murdered emperor had been profitably exchanged for the Divus Julius, and just as the gods had founded the old Rome of Romulus, so again it was a god who had laid the foundations of the empire over which his successor was ruling.
But Augustus was not content with this; it was all very well for men to look upon the god Caesar as an illustration of justification after death, as an example of how heaven could right the wrongs of earthly existence, but that was not sufficient; the punishment of those who caused his earthly downfall must be emphasised, it must be shown that the gods were quite as much interested in punishing the sinner as in rewarding the righteous man who was sinned against. It was one thing to transfer one's ancestors to the gods, it was quite another thing to take measures to keep oneself from following in their footsteps, even though their last estate was theoretically desirable. Hence side by side with the cult of the Divus Julius went that of Mars Ultor, Mars the Avenger. The circumstances of the beginning of the cult show that it was no mere poetical title but a genuine cult-name born in an earnest moment: for the great temple subsequently built to Mars under this cognomen was vowed by Augustus "in behalf of vengeance for his father," in the war against the slayers of Caesar, Brutus and Cassius. This temple, vowed at Philippi in B.C. 42, was so slow in building that in the meantime Augustus erected a small round temple to Mars Ultor on the Capitoline. This was dedicated May 12, B.C. 20. In the years which followed Augustus proceeded with the difficult and extremely expensive task of purchasing property for his own Forum, and here was built and dedicated, August 1, B.C. 2, the great temple of Mars Ultor. But aside from being a very present reminder of the vengeance which the gods had in store for those who killed a Caesar, it stood also for the Julian house, for Mars was not alone in the temple but with him was Venus, the ancestral mother of the family of Julius and Augustus; and thus was once more emphasised the connexion between the ancestors of the ruling house and the great ancestor Mars, from whom all Romans were sprung.
A temple possessed of such strong associations with the imperial family became instantly a centre of their family worship, and in this respect produced another rival to the cult of Juppiter on the Capitoline. In connexion namely with the putting on of the toga virilis the members of the imperial family went to the temple of Mars Ultor instead of following the immemorial custom of ascending the Capitol to the shrine of Juppiter Optimus Maximus. More important yet the insignia of the triumph, which had always been in the keeping of the Capitoline Juppiter even before he was Optimus Maximus and while he was only the "Striker," Feretrius, were now preserved in the temple of Mars Ultor.
With all the state worshipping Apollo, the god of the emperor's own family, on the Palatine, celebrating the divinity of his ancestor the god Julius in the Roman Forum, and acknowledging Mars as the avenger of all those who did the emperor harm, in the emperor's own new Forum, it might have seemed to a less far-seeing man that religion had been sufficiently pressed into the service of the royal family. But so it did not seem to Augustus. These cults were all three of them essentially new, and new cults may, to be sure, easily become prominent; they usually do, but the test comes with time whether there is external pressure sufficiently continuous to give permanency to this prominence. As a matter of fact not one of these three cults continued later to hold the rank in importance which it had under Augustus. On the other hand if one went low enough and looked sufficiently deep down certain elements in the religious life of the community could be found which continued almost unchanged from century to century. These were the simple elements which were involved in family worship, the sacrifices at the hearth of Vesta, and those to the Genius of the master of the house. Here simple beliefs and elementary cult acts had continued virtually unchanged from the very earliest period down to the present. These cults did not need any formal restoration on the part of the emperor, for they had not experienced the decline which the other cults had suffered, but by just so much more they would afford a firm foundation for his empire and his own rule if he could in some way succeed in connecting them with himself. In the case of Vesta this was comparatively easy. The Pontifex Maximus was the guardian of the Vestal virgins, and thus on March 6, B.C. 12, when Augustus became Pontifex Maximus, it was quite natural that there should be a festival to Vesta and that the day should continue as a public holiday. The Pontifex Maximus however was supposed to live in the Regia down in the Forum, where Julius Caesar as Pontifex Maximus had actually lived. This Augustus did not desire to do, hence he gracefully gave up the Regia to the Vestal virgins and made his official residence in his own house on the Palatine, fulfilling the religious requirements by consecrating a part of that house. On a portion of the section thus consecrated a temple of Vesta was built and dedicated April 28, B.C. 12. This was strictly speaking his own "Vesta," the hearth of his own house, but the prominence of the temple of Vesta there had an effect similar to the prominence of the temple of Apollo on the Palatine, and the whole state began thus to worship at the hearth of the emperor, and in time the emperor was worshipped at each individual hearth.
But the crowning touch of Augustus's religious policy was yet to come; this was the establishment of the worship of the Genius of the emperor. After Actium and in the earlier years of his reign it is certain that Augustus would not have thought of putting himself, even in the spiritualised form of his Genius, before the people as an object of worship. But the tendency to emperor-worship which Oriental influence had brought with it was not without its effects on the emperor himself, and perhaps these effects were all the stronger because of his valiant struggle against it. Then too the state was already worshipping the gods of his family, even Vesta Augusta, the goddess of his own hearth. He had become in substance, even if not yet in name, the father of his country. It had been an immemorial custom that the members of the household should worship the Genius of the master of the house. In every household in Rome that custom still existed. It was a very logical step, and one therefore which a Roman could easily take, to carry out the analogy of the family and to allow the whole state to worship the Genius of the emperor, who was the head of the family of the state. The idea therefore was not at all incongruous, nor was the way in which it was carried out, though the latter was so ingenious as to deserve special consideration.
In the old days when Rome was a farming community, the guardianship of the gods over the fields was one of the most important elements in religious life. The gods were above all the protectors of the boundary lines, and thus it came to pass that where two roads crossed and thus the corners of four farms came together the deities protecting these farms were worshipped together as the Lares Compitales, the Lares of the compita or cross-roads. Curiously enough this worship was later extended to the crossing of city streets, and as was natural it became more highly organised in the city than it had been in the country. Regular associations, collegia, were formed to look after the details of the worship, headed by the magistri vicorum, who were however not public officials but merely the elected heads of these colleges, men mainly from the lower ranks of society. The contagion of civil and political strife affected these colleges as well as their more aristocratic parallels, higher up in the social scale, and turned them into local political clubs. The part played by these clubs in the civil struggles which occupied the last century of the republic was such that the Senate in B.C. 64 was compelled to dissolve them, though they were restored again six years later and existed until Caesar destroyed them entirely. But now Augustus was creating a new organisation for the city, dividing it into fourteen regions, each region containing a certain number of subdivisions called vici. The old "colleges of the cross-roads" afforded him just the sort of opportunity which he never failed to seize, that of seeming to restore a neglected republican institution, and at the same time of making it into a support of the monarchy. The colleges had antiquity in their favour, and their repeated suppression was clear proof of their power. They must be recognised and taken over by the state, their officials must be made into officials of the state, but, most important, their worship must be permeated with the imperial idea. This was where Augustus's skill showed itself. At every shrine of the cross-roads where of old the two Lares had been worshipped alone, a third image now took its place between them. This was the Genius Augusti, who thus formed henceforth an integral part of the local worship of every part of the city. Under the presiding Genius Augusti the Lares themselves began to be known as the Lares Augusti and the cult grew in popularity so that it began to extend through all of Italy and even through the provinces of the empire, and wherever the Lares went, along with them went the worship of the Genius of the emperor.
Now that we have seen what Augustus did, the question arises irresistibly as to the measure of his success. There can be no question but that he was successful in obtaining the immediate object which he was seeking after. A formal religious life was unquestionably brought into being, and such strength as that life had was exerted in behalf of the empire. This is only in part true of the city but it is absolutely true of the provinces, where after all in the long run the balance of power was bound to lie. In every case the religious reform, begun in the city, spread rapidly through the rest of Italy and out into the provinces. There the negative elements, which hindered its growth in Rome itself, were absent. For the provinces the empire was all gain, and even a bad emperor was far better than none at all.
The politics of Augustus had recreated the religion which the politics of the last century of the republic had destroyed, had recreated it in as far as political considerations could. But the spirit of scepticism which had made possible the political abuse of religion could not be driven out by any further application of politics. A form might be created, both the paraphernalia of temples and the hierarchy of priests whose business it was to perform certain cult acts, but there the power of enactment ceased. In the main the religious life of the people went on for good or for ill entirely independent of these things. All that was alive and real in the simple domestic cult went on down into the empire, and those who were faithful were faithful still. The cults of the Orient, against which Augustus had done all that he dared, still captured the minds of the vast majority of the people, and a Mithras or an Isis meant infinitely more than a Mars or a Vesta, even if Mars were the avenger of a Caesar, and Vesta the goddess of the living emperor's own hearth. Among the more intellectual classes the folly of the one set of gods, the darlings of the common people, was felt as keenly as the folly of the others, those who had been worshipped by the men of former days. Philosophy, which had had its share in the breakdown of faith, beginning in the days of the Punic wars, was now offering out of itself a substitute for the faith which it had taken away. It no longer contented itself with a destructive criticism which resulted in a negative view of life, but in Stoicism at least it strove to provide something sufficiently constructive to afford not only a rule of living but also an inspiration to live.
