The elements of divination from the flight of birds were derived either from the significant notes and sounds of their voices, or from the manner in which their wings were flapped or their flight conducted. If the bird flew from the left to the right of the augur, it was considered a happy omen; if the flight was in the opposite direction, the enterprise in hand had to be abandoned or at least delayed. Augury by flight was usually applied to eagles and vultures, while woodpeckers, ravens, crows, and screech owls announced the will of the gods by note. The direction from which the note came, usually determined the nature of the augury. But, in the case of the screech owl, the sounds were always of evil omen, from whatever side they came. And those who have been so unfortunate as to hear its mournful, desolate and God-forsaken tones will not be disposed to censure either the Romans or their gods for the low esteem in which they held this bird.
Again, it was a principle of Roman augury that auspices could be neutralized or overcome. If a crow furnished an omen, and an eagle gave another which was opposed to it, the first sign was wiped out, because the eagle was a larger and nobler bird than the crow. And, as in the case of prayer, so also in the matter of the auspices, a disturbing sound would destroy the effect of the augury. The squeak or cry of a mouse would destroy a message from Jupiter conveyed in the scream of an eagle.
But the most potent manifestation of the divine mind, among the ancient Romans, was that derived from thunder and lightning. Lightning to them was the sovereign expression of the will of the gods; and a single flash blotted out every other sign and token. It was an irrevocable presage and could not be remotely modified or evaded. It came directly from the hand of the deity and was an emphatic revelation of the divine mind. All places struck by lightning were considered sacred and were consecrated to the god who had sent the bolt. Upon the spot where it fell, an altar was raised and an inclosure formed. The service of consecration consisted in burying the lightning, that is, in restoring the earth thrown up by it, and in the sacrifice of a two-year-old sheep. All such places were considered hallowed spots and it was impious and sacrilegious to touch them or even look at them. The gods deprived of reason those who destroyed the altars and sacred inclosures of these places.
These various methods of ascertaining the will of the deities were employed in every important transaction of Roman public and private life. At times, all of them coöperated on occasions of vast import and when the lives and destinies of great men were involved.
The following single paragraph from Suetonius contains allusions to all the modes of divination which we have just discussed:
After the death of Cæsar, upon his return from Apollonia as he was entering the city, on a sudden, in a clear and bright sky a circle resembling the rainbow surrounded the body of the sun; and immediately afterwards, the tomb of Julia, Cæsar's daughter, was struck by lightning. In his first consulship whilst he was observing the auguries, twelve vultures presented themselves as they had done to Romulus. And when he offered sacrifice, the livers of all the victims were folded inward in the lower part; a circumstance which was regarded by those present, who had skill in things of that nature, as an indubitable prognostic of great and wonderful fortune.[137]
The interpretation of dreams also formed an important part in the determination of the will of the gods, not only among the Romans, but among all ancient nations. The literature of antiquity, both sacred and profane, is filled with dreams. Whether the biographer is Matthew or Plutarch, dreams appear on the pages of both. Chrysippus made a collection of prophetical dreams in order to explain their meaning. Both Galen and Hippocrates believed that dreams were sent by the gods to men. Artemidorus wrote a treatise on the subject, and in it he assures us that it was compiled at the express bidding and under the direction of Apollo himself.
It was in a dream that Joseph was warned not to put away Mary his wife.[138] It was also in a dream that an angel voice warned him to flee into Egypt with the infant Savior to escape the murderous designs of Herod.[139] Nearly every great event, both in Greek and Roman history, seems to have been heralded or attended by dreams. The following account is given by Suetonius of the dreams of Quintus Catulus and Marcus Cicero presaging the reign of Augustus:
Quintus Catulus had a dream, for two nights successively after his dedication of the Capitol. The first night he dreamt that Jupiter out of several boys of the order of the nobility who were playing about his altar, selected one, into whose bosom he put the public seal of the commonwealth, which he held in his hand; but in his vision the next night, he saw in the bosom of Jupiter Capitolinus, the same boy; whom he ordered to be removed, but it was forbidden by the God, who declared that it must be brought up to become the guardian of the state. The next day, meeting Augustus, with whom till that hour he had not the least acquaintance, and looking at him with admiration, he said he was extremely like the boy he had seen in his dream. Some gave a different account of Catulus's first dream, namely that Jupiter, upon several noble lads requesting of him that they might have a guardian, had pointed to one amongst them, to whom they were to prefer their requests; and putting his fingers to the boy's mouth to kiss, he afterwards applied them to his own.
Marcus Cicero, as he was attending Caius Cæsar to the Capitol, happened to be telling some of his friends a dream which he had the preceding night, in which he saw a comely youth let down from heaven by a golden chain, who stood at the door of the Capitol, and had a whip put into his hands by Jupiter. And immediately upon sight of Augustus, who had been sent for by his uncle Cæsar to the sacrifice, and was as yet perfectly unknown to most of the company, he affirmed that it was the very boy he had seen in his dream. When he assumed the manly toga, his senatorian tunic becoming loose in the seam on each side, fell at his feet. Some would have this to forebode, that the order of which that was the badge of distinction, would some time or other be subject to him.[140]
