The differentiation of Greek and Roman religion is to be explained by the culture-history of the two peoples; and that, in turn, was determined by their geographical situation and their special contacts. Roman life was made systematically agricultural and militarist by its initial circumstances, where Greek life in civilized Asia Minor became industrial, artistic, and literary. The special “genius” of Homer, or of various members of an order of bards developed by early colonial-feudal Grecian conditions, would indeed count for much by giving permanent artistic definiteness of form to the Greek Gods, where the early Romans, leaving all the vocal arts mainly to the conservative care of their women and children as something beneath adult male notice, missed the utilization of poetic genius among them till they were long past the period of romantic simplicity (cp. Mommsen, bk. i, ch. 15; Eng. tr. 1894, vol. i, pp. 285–300). Hence the comparative abstractness of their unsung Gods (cp. Schwegler, Römische Geschichte, i, 225–28, and refs.; Boissier, La religion romaine, as cited, i, 8), and the absence of such a literary mythology as was evolved and preserved in Greece by local patriotisms under the stimulus of the great epopees and tragedies. The doctrine that “the Italian is deficient in the passion of the heart,” and that therefore “Italian” literature has “never produced a true epos or a genuine drama” (Mommsen, ch. 15, vol. i, p. 284), is one of a thousand samples of the fallacy of explaining a phenomenon in terms of itself. Teuffel with equal futility affirms the contrary: “Of the various kinds of poetry, dramatic poetry seems after all to be most in conformity with the character of the Roman people” (as cited, p. 3; cp. p. 28 as to the epos). On the same verbalist method, Mommsen decides as to the Etruscan religion that “the mysticism and barbarism of their worship had their foundation in the essential character of the Etruscan people” (ch. 12, p. 232). Schwegler gives a more objective view of the facts, but, like other German writers whom he cites, errs in speaking of early deities like Picus as “only aspects of Mars,” not realizing that Mars is merely the surviving or developed deity of that type. He also commits the conventional error of supposing that the early Roman religion is fundamentally monotheistic or pantheistic, because the multitudinous “abstract” deities are “only” aspects of the general force of Nature. The notion that the Romans did not anthropomorphize their deities like all other peoples is a surprising fallacy.
Thus when Rome, advancing in the career of conquest, had developed a large aristocratic class, living a city life, with leisure for intellectual interests, and had come in continuous contact with the conquered Grecian cities of Southern Italy, its educated men underwent a literary and a rationalistic influence at the same time, and were the more ready to give up all practical belief in their own slightly-defined Gods when they found Greeks explaining away theirs. Here we see once more the primary historic process by which men are led to realize the ill-founded character of their hereditary creeds: the perception is indirectly set up by the reflective recognition of the creeds of others, and all the more readily when the others give a critical lead. Indeed, Greek rationalism was already old when the Romans began to develop a written and artistic literature: it had even taken on the popular form given to it by Evêmeros a century before the Romans took it up. Doubtless there was skepticism among the latter before Ennius: such a piece of religious procedure as the invention of a God of Silver (Argentinus), son of the God of Copper (Æsculanus), on the introduction of a silver currency, 269 B.C., must have been smiled at by the more intelligent.[4]
Mommsen states (ii, 70) that at this epoch the Romans kept “equally aloof from superstition and unbelief,” but this is inaccurate on both sides. The narrative of Livy exhibits among the people a boundless and habitual superstition. The records of absurd prodigies of every sort so throng his pages that he himself repeatedly ventures to make light of them. Talking oxen, skies on fire, showers of flesh, crows and mice eating gold, rivers flowing blood, showers of milk—such were the reports chronically made to the Roman government by its pious subjects, and followed by anxious religious ceremonies at Rome (cp. Livy, iii, 5, 10; x, 27; xi, 28–35; xxiv, 44; xxvii, 4, 11, 23, etc., etc. In the index to Drakenborch’s Livy there are over five columns of references to prodigia). On the other hand, though superstition was certainly the rule, there are traces of rationalism. On the next page after that cited, Mommsen himself admits that the faith of the people had already been shaken by the interference allowed to the priestly colleges in political matters; and in another chapter (bk. ii, ch. 13; vol. ii, 112) he recalls that a consul of the Claudian gens had jested openly at the auspices in the first Punic war, 249 B.C. The story is told by Cicero, De natura Deorum, ii, 3, and Suetonius, Tiberius, c. 2. The sacred poultry, on being let out of their coop on board ship, would not feed, so that the auspices could not be taken; whereupon the consul caused them to be thrown into the water, etiam per jocum Deos inridens, saying they might drink if they would not eat. His colleague Junius in the same war also disregarded the auspices; and in both cases, according to Balbus the Stoic in Cicero’s treatise, the Roman fleets were duly defeated; whereupon Claudius was condemned by the people, and Junius committed suicide. Cp. Valerius Maximus, l. i, c. iv, § 3.
Such stories would fortify the age-long superstition as to auspices and omens, which was in full force among Greek commanders as late as Xenophon, when many cultured Greeks were rationalists. But it was mainly a matter of routine, in a sphere where freethought is slow to penetrate. There was probably no thought of jesting when, in the year 193 B.C., after men had grown weary alike of earthquakes and of the religious services prescribed on account of them; and after the consuls had been worn out by sacrifices and expiations, it was decreed that “if on any day a service had been arranged for a reported earthquake, no one should report another on that day” (Livy, xxxiv, 55). Cato, who would never have dreamt of departing from a Roman custom, was the author of the saying (Cicero, De Div. ii, 24) that haruspices might well laugh in each other’s faces. He had in view the Etruscan practice, being able to see the folly of that, though not of his own. Cp. Mommsen, iii, 116. As to the Etruscan origin of the haruspices, in distinction from the augurs, see Schwegler, i, 276, 277; Ihne, Eng. ed. i, 82–83, note; and O. Müller as there cited.
But it is with the translation of the Sacred History of Evêmeros by Ennius, about 200 B.C., that the literary history of Roman freethought begins. In view of the position of Ennius as a teacher of Greek and belles lettres (he being of Greek descent, and born in Calabria), it cannot be supposed that he would openly translate an anti-religious treatise without the general acquiescence of his aristocratic patrons. Cicero says of him that he “followed” as well as translated Evêmeros;[5] and his favourite Greek dramatists were the freethinking Euripides and Epicharmos, from both of whom he translated.[6] The popular superstitions, in particular those of soothsaying and divination, he sharply attacked.[7] If his patrons all the while stood obstinately to the traditional usages of official augury and ritual, it was in the spirit of political conservatism that belonged to their class and their civic ideal, and on the principle that religion was necessary for the control of the multitude. In Etruria, where the old culture had run largely to mysticism and soothsaying on quasi-oriental lines, the Roman government took care to encourage it, by securing the theological monopoly of the upper-class families,[8] and thus set up a standing hot-bed of superstition. In the same spirit they adopted from time to time popular cults from Greece, that of the Phrygian Mother of the Gods being introduced in the year 204 B.C. The attempt (186 B.C.) to suppress the Bacchic mysteries, of which a distorted and extravagant account[9] is given by Livy, was made on grounds of policy and not of religion; and even if the majority of the senate had not been disposed to encourage the popular appetite for emotional foreign worships, the multitude of their own accord would have introduced the latter, in resentment of the exclusiveness of the patricians in keeping the old domestic and national cults in their own hands.[10] As now eastern conquests multiplied the number of foreign slaves and residents in Rome, the foreign worships multiplied with them; and with the worships came such forms of freethought as then existed in Greece, Asia Minor, and Egypt. In resistance to these, as to the orgiastic worships, political and religious conservatism for a time combined. In 173 B.C. the Greek Epicurean philosophers Alkaios and Philiskos were banished from the city,[11] a step which was sure to increase the interest in Epicureanism. Twelve years later the Catonic party carried a curt decree in the Senate against the Greek rhetors,[12] uti Romae ne essent; and in 155 the interest aroused by Carneades and the other Athenian ambassadors led to their being suddenly sent home, on Cato’s urging.[13] It seems certain that Carneades made converts to skepticism, among them being the illustrious Scipio Æmilianus.[14] In the sequel the Greeks multiplied, especially after the fall of Macedonia,[15] and in the year 92 we find the censors vetoing the practices of the Latin rhetors as an unpleasing novelty,[16] thus leaving the Greeks in possession of the field.[17] But, the general social tendency being downwards, it was only a question of time when the rationalism should be overgrown by the superstition. In 137 there had been another vain edict against the foreign soothsayers and the worshippers of Sabazius;[18] but it was such cults that were to persist, while the old Roman religion passed away,[19] save insofar as it had a non-literary survival among the peasantry.
§ 2
While self-government lasted, rationalism among the cultured classes was fairly common. The great poem of Lucretius, On the Nature of Things, with its enthusiastic exposition of the doctrine of Epicurus, remains to show to what a height of sincerity and ardour a Roman freethinker could rise. No Greek utterance that has come down to us makes so direct and forceful an attack as his on religion as a social institution. He is practically the first systematic freethinking propagandist; so full is he of his purpose that after his stately prologue to alma Venus, who is for him but a personification of the genetic forces of Nature, he plunges straight into his impeachment of religion as a foul tyranny from which thinking men were first freed by Epicurus. The sonorous verse vibrates with an indignation such as Shelley’s in Queen Mab: religion is figured as horribili super aspectu mortalibus instans; a little further on its deeds are denounced as scelerosa atque impia, “wicked and impious,” the religious term being thus turned against itself; and a moving picture of the sacrifice of Iphigeneia justifies the whole. “To so much of evil could religion persuade.” It is with a bitter consciousness of the fatal hold of the hated thing on most men’s ignorant imagination that he goes on to speak of the fears[20] so assiduously wrought upon by the vates, and to set up with strenuous speed the vividly-imagined system of Epicurean science by which he seeks to fortify his friend against them. That no thing comes from nothing, or lapses into nothing; that matter is eternal; that all things proceed “without the Gods” by unchanging law, are his insistent themes; and for nigh two thousand years a religious world has listened with a reluctant respect. His influence is admitted to have been higher and nobler than that of the religion he assailed.
“Lucretius was the first not only to reveal a new power, beauty, and mystery in the world, but also to communicate to poetry a speculative impulse, opening up, with a more impassioned appeal than philosophy can do, the great questions underlying human life—such as the truth of all religious tradition, the position of man in the universe, and the attitude of mind and course of conduct demanded by that position.” (Sellar, Roman Poets of the Republic: Virgil, 1877, p. 199.)
“In the eyes of Lucretius all worship seemed prompted by fear and based on ignorance of natural law.... But it is nevertheless true that Lucretius was a great religious poet. He was a prophet, in deadly earnest, calling men to renounce their errors both of thought and conduct.... We may be certain that he was absolutely convinced of the truth of all that he wrote.” (W. Warde Fowler, Social Life at Rome in the Age of Cicero, 1909, pp. 327–28.)
