Fifteen learned and experienced augurs observed the phenomena of nature and studied the flight of birds as a means of directing the actions of the state.
Fifteen keepers of the Sibylline books read the pages of their treasures and from them divined coming events.
Six Vestals, immaculate in their virginity, guarded the Roman sacred fire, and presided at the national hearthstone of the Roman race.
Seven epulos conducted the solemn processions and regulated the religious ceremonies at the annual festivals of the gods.
Fifteen flamens were consecrated to the service of separate deities. Those of Jupiter, Mars, and Quirinus were held in the highest esteem. The Flamen Dialis, or priest of Jupiter, was loaded down with religious obligations and restrictions. He was not permitted to take an oath, to ride, to have anything tied with knots on his person, to look at a prisoner, see armed men, or to touch a dog, a goat, or raw flesh, or yeast. He was not allowed to bathe in the open air; nor could he spend the night outside the city. He could resign his office only on the death of his wife. The Salians were priests of Mars, who, at festivals celebrated in honor of the war-god, danced in heavy armor, and sang martial hymns.
Roman Forms of Worship.—Roman worship was very elaborate and ceremonial. It consisted of sacrifices, vows, prayers, and festivals. With the exception of the ancient Hebrews, the Romans were the greatest formalists and ritualists of antiquity. Every act of Roman public and private life was supposed to be framed in accordance with the will of the gods. There was a formula of prayer adapted to every vicissitude of life. Cæsar never mounted his chariot, it is said, that he did not repeat a formula three times to avert dangers.
A painful exactness in the use of words was required in the offering of a Roman prayer. A syllable left out or a word mispronounced, or the intervention of any disturbing cause of evil import, would destroy the merit of the formula. The Romans believed that the voice of prayer should not be interrupted by noises or bad omens. And that the sound of evil augury might not be heard at the moment of supplication, they were in the habit of covering their ears. Musical notes of favorable import were not objectionable, and frequently flutes were played while the prayer was being offered to chase away disturbing sounds. At other times, the priests had special assistants whose duty it was to maintain silence during the recital of the formula. But, if the ceremony was successful, if the language had been correctly pronounced, without the omission or addition of a word; if all disturbing causes and things of evil omen had been alienated from the services, then the granting of the prayer was assured, regardless of the motive or intention of the person praying. It should be remembered that piety and faith were not necessary to the efficacy of Roman prayer. Ceremonial precision, rather than purity of heart, was pleasing to the Roman gods. A peculiar element entered into the religions of both the ancient Romans and the ancient Hebrews. It was the principle of contract in an almost purely juristic sense. Both the Romans and the Hebrews believed that if the divine law was obeyed to the letter, their deities were under the strictest obligation to grant their petitions.
Under the Roman form of worship, a peculiar act of supplication was performed by the suppliant who kissed his right hand, turned round in a circle by the right, and then seated himself upon the ground. This was done in obedience to one of the laws of Numa. The circular movement of the earth, it was thought, was symbolized by the turning round in a circle; and the sitting down indicated that the suppliant was confidant that his prayer would be granted.
The Romans believed that prayers were more efficacious if said in the immediate presence and, if possible, in actual contact with the image of the god. The doorkeepers of the temple were frequently besieged by suppliants who begged to be admitted into the inclosures of the sacred places where they might pray to the deity on the spot.
On account of the vast numbers of the gods, the Romans were sometimes at a loss to know which one to address in prayer. Unlike the Greeks, they had no preferences among their deities. Each was supplicated in his turn according to the business in hand. But they were frequently in doubt as to the name of the god who had control of the subject-matter of their petitions. In such cases, the practical genius of the Roman people served them well. They had recourse to several expedients which they believed would insure success. When in doubt as to the particular divinity which they should address in supplication, they would, at times, invoke, in the first place, Janus, the god of all good beginnings, the doorkeeper, so to speak, of the pantheon, who, it was believed, would deliver the prayer to the proper deity. At other times, in such perplexity, they would address their petitions to a group of gods in which they knew the right one was bound to be. It sometimes happened that they did not know whether the deity to be supplicated was a god or goddess. In such an emergency, they expressed themselves very cautiously, using the alternative proviso: "Be thou god or goddess." At other times, in cases of extreme doubt, they prayed to all the deities at once; and often, in fits of desperation, they dismissed the entire pantheon and addressed their prayers to the Unknown God.
