I. Auspicia Privata

Auspices (auspicia) were signs sent by the gods through which they declared their will to men. Those given in answer to prayer were impetrativa (or impetrita), those sent unasked oblativa. The first were necessarily favorable; the second might be either favorable or the contrary.[578] To take or to hold auspices was to seek such signs in due form. Auspicia, or the singular auspicium, also designated the right or the power to perform the function. They were not a means of prophecy of future events but of ascertaining whether the deity approved a proposed action.[579] With reference to their object and to the persons qualified to take them, they were of two kinds, private and public. Whereas the public auspices, taken in behalf of the state, belonged exclusively to magistrates, the private were open to all;[580] and in early times a Roman always resorted to them before beginning any important business.[581] Though it was permissible to consult any deity,[582] the greatest weight attached to the approval of the supreme god Jupiter.[583]

The plebeians, who as long as they were excluded from the magistracies were necessarily debarred from the auspicia publica, enjoyed equally with the patricians all private rights of religion; in fact if the nobles had wished, they possessed no legal means of preventing the holding of auspices or the performance of any other sacred rite in private plebeian houses. Not only is it stated that all had a right to auspicate,[584] but the formula for summoning troops given by Cincius[585] implies that the soldiers, who were mainly plebeian, were accustomed to perform the rite. We find accordingly the elder Cato, a plebeian, attending to the ceremony in his own home.[586] The patricians, however, who believed themselves to be nearer and dearer to the gods than were the plebeians, and who in their struggle to keep themselves a closed caste and the offices barred against the lower social class, declared that conubium if granted would disturb the private as well as public auspices.[587] But this assertion need not signify that the plebeians had no private auspices, it might indicate merely a difference between the plebeian and patrician ceremonies, naturally implying the superiority of the latter. Again when on a certain occasion according to Livy a tribune of the plebs inquired of a patrician why a plebeian could not be made consul, the reply was that no plebeian had the auspices, reiterating that the decemvirs had forbidden conubium to prevent the disturbance of the ceremony by uncertainty of birth.[588] Reference might here be simply to the auspicia publica, with which alone the consul was concerned. However this may be, the patrician claim was indignantly repudiated by the plebeians, and the historian can say no more than that it was “perhaps true.” Another passage from Livy usually interpreted in support of the theory that the patricians alone had private auspices represents them, before the opening of the offices to the commons, as saying, “So peculiar to us are the auspices that not only the patrician magistrates whom the people choose are elected under the auspices, but we ourselves under the sanction of the same rite without a vote of the people appoint the interrex, and we as private persons hold auspices, which they do not hold even as magistrates.”[589] This passage is perfectly intelligible to one who bears in mind that in the late republic private auspices had disappeared,[590] and that therefore when the word auspicia is used without qualification by a late republican or imperial writer, it always has reference to the public ceremonies.[591] In the quotation just given, accordingly, nothing more is meant than that the patricians, who have the exclusive right to the offices, are alone competent to perform the public religious ceremonies which belong to the magistrates. Reference in the quotation to the auspices of private persons signifies that when there was no magistrate competent to hold the election of consuls, the public auspices returned to the senate, the patrician members of which proceeded under auspication to appoint an interrex for holding the elections. In this case the senatorial patricians, it was asserted, attended to the ceremony not as magistrates but as private persons, though the rites were themselves public. As distinguished from magistrates, the senators were privati. It was not, then, as mere citizens but as patrician members of the senate that they performed the rite. Further light is thrown on this subject by the fact that in the agitation for the opening of the augural and pontifical colleges to the plebeians in 300, the patricians repeated the assertion that with them alone were auspices, they alone had family (gens), they alone possessed true imperium and auspicium in peace and war.[592] This claim they had the effrontery to make despite the fact that plebeian consuls had been taking public auspices for more than sixty years. In the pride of their blood they claimed that theirs alone were strictly legal (iustum). Notwithstanding such partisan assertions the facts thus far adduced lead unmistakably to the conclusion that the plebeians equally with the patricians enjoyed the right to private auspices.[593]

II. Auspicia Publica Impetrativa

The right to public auspices belonged primarily to patrician magistracies[594]—those which in the early republic were filled only by patricians, but which continued to be called patrician after they were open to plebeians. All elections and appointments to such offices were auspicated;[595] and their incumbents were expected to seek the previous approval of Jupiter for every important act of their administration.[596] The king, interrex, dictator, consuls, praetors, and censors had the auspicia maxima; the others the minora.[597] The praetor, as colleague of the consuls, was elected under the same auspices with them, that is, in the same meeting of the assembly, whereas the censors, not being colleagues of the consuls, were elected under different auspices. Between magistrates who were not colleagues there could be no collision in the auspicia impetrativa; those of the censors neither strengthened nor vitiated those of the consuls or praetors, nor were strengthened or vitiated by them. In case of a conflict between colleagues, the greater auspices annulled the lesser, and equal auspices annulled each other.[598] For the exercise of a function properly belonging to a magistracy, the incumbent performed the ceremony at his own will and pleasure, unless expressly forbidden by a superior;[599] but one who undertook a deputed duty had to ask the auspicium of a magistrate who was competent to perform the duty in his own right. Thus the quaestor, who was not qualified by right of his office to call the comitia centuriata, found it necessary to do so in his capital prosecutions. In such a case he asked of the praetor or consul the right to hold auspices for summoning this assembly.[600] Whether the pontifex maximus held auspices in his own name, or was obliged, like the quaestor, to apply for them to a higher secular official, is unknown; at all events it was necessary for him to auspicate the comitia calata, over which he presided.[601] It seems probable that the tribunes originally did not have the right as they were not magistrates; but when they came to be so considered, they acquired the auspicium. All magistrates—necessarily including the tribunes—who convoked the senate had previously to perform the ceremony;[602] Cicero[603] seems to include the tribunes among the magistrates who had the auspicium; and as further proof the very expression “patriciorum (magistratuum) auspicia”[604] used by Messala implies the existence of “plebeiorum magistratuum auspicia.” It was not the custom of the tribunes, however, to auspicate their assemblies of the plebs.[605]

For assistance in auspication the magistrate summoned any person he pleased, who was rarely if ever a public augur.[606] An augur,[607] whether private or official, was a person who knew how to hold and to interpret auspices.[608] A college of public augurs[609] for the service of the state was established in the most primitive times. Probably comprising three members, one from each tribe, it was gradually increased till under Sulla it reached fifteen.[610] The members of the college were neither magistrates[611] nor prophets. They were rather the wise,[612] experienced[613] keepers and expounders of a sacred science and art[614]—the “interpreters of Jupiter All-Great and Good.”[615] Having to do with religion, they were sacerdotes, like the pontiffs, though not offerers of sacrifice (flamines).[616] The functions which they exercised independently of the magistrates included the inauguration of religious officials (inaugurare sacerdotes), the blessing of fields twice a year, and of the people after the close of a war.[617] In attending to such duties (auguria) only did they exercise their right to the auspices.[618] In a dependent though far more influential position they acted as the professionally skilled advisers and assistants of the magistrates in all matters of peace and war.[619] If a magistrate was not himself an augur,[620] it was of the utmost importance to have their service; for the science of discovering and interpreting the divine omens was intricate, mistakes were easy, and the slightest oversight might vitiate the whole business in hand. When in doubt as to the validity of the ceremony, either the magistrate to whom it belonged or the senate could refer the case to the college of augurs, which thereupon gave an opinion in the form of a decree. The senate then acted on the matter according to its judgment.[621] In case a law had been passed, a magistrate elected, or any public act performed against its wishes, it could inquire of the college of augurs whether the election or other act had been duly auspicated; and should a defect be alleged, the senate could annul the act or request the magistrate to resign. It required unusual courage in a man to keep himself in office in defiance of the authority of the senate and of the religious feeling of the whole people.[622] These considerations account for the great importance attaching to the presence of augurs in the comitia—a subject to be treated in another connection.[623]

The service of augurs was most needed in establishing the terrestrial templum[624]—a carefully marked out, oriented spot which the magistrate occupied while performing the rite.[625] Whereas the commander of an army generally made use of chicken auspices (signa ex tripudiis), which did not require their assistance,[626] they were doubtless always called upon to institute templa in or near the city.[627] For the exercise of their art they divided the world, so far as known to them, into augural districts. The central district was the city, limited by the pomerium,[628] beyond which, probably extending to the first milestone,[629] lay a zone termed ager effatus,[630] whose boundaries were marked by cippi.[631] The rest of the world within their sphere of knowledge they divided into ager Romanus, which in its larger sense included the two districts above mentioned, Gabinus, peregrinus, hosticus, and incertus.[632] For the comitia the two inner regions were alone important: (1) the auspication of assemblies held in the city had to be performed within the pomerium; (2) as often as the magistrate in passing from the city to the Campus Martius to hold the comitia centuriata crossed the pomerium,[633] or more strictly the brook Petronia,[634] he was obliged to take the special auspices of crossing. Beyond the ager effatus assemblies were not ordinarily held.

Originally the most common form of divination must have been the watching of the flight of birds, for it is from this ceremony that the word auspicium is derived.[635] Legend accordingly asserts that Romulus founded the city on the Palatine under the auspices of twelve vultures.[636] Before the end of the republic, however, all other forms of public auspicia impetrativa in the city had given way to the caelestia, especially the lightning and thunder.[637] The reason is that the heavenly signs could be most easily understood and carried greatest weight; whereas other auspices had to be held for each individual act, the celestial omens of the morning served the magistrate for all his undertakings during the entire day.[638] The effect of heavenly signs on assemblies of the people, however, was peculiar. Not only were comitia and contiones interrupted by storms;[639] not only was it impious to hold an assembly while it was lightning or thundering,[640] but even while the magistrate was auspicating at daybreak, if a flash of lightning appeared on the left—a sign favorable for every other undertaking—he dared not hold the assembly on that day.[641] Some favorable comitial sign the magistrate was supposed to perceive,[642] but what it was we do not know.
