DIVISIONS OP DIVINATION BY THE ANCIENTS—PRODIGIES, ETC.
Divination was divided by the ancients into artificial and natural. The first is conducted by reasoning upon certain external signs, considered as indications of futurity; the other consists in that which presages things from a mere internal sense, and persuasion of the mind, without any assistance of signs; and is of two kinds, the one from nature, and the other by influx. The first supposes that the soul, collected within itself, and not diffused or divided among the organs of the body, has from its own nature and essence, some fore-knowledge of future things; witness, for instance, what is seen in dreams, ecstasies, and on the confines of death. The second supposes the soul after the manner of a mirror to receive some secondary illumination from the presence of God and other spirits. Artificial divination is also of two kinds: the one argues from natural causes, as in the predictions of physicians relative to the event of diseases, from the tongue, pulse, etc. The second the consequence of experiments and observations arbitrarily instituted, and is mostly superstitious. The systems of divination reduceable under these heads are almost incalculable. Among these were the Augurs or those who drew their knowledge of futurity from the flight, and various other actions of birds; the Aruspices, from the entrails of beasts; palmestry or the lines of the hands; points marked at random; numbers, names, the motions of a scene, the air, fire, the Praenestine, Homerian, and Virgilian lots, dreams, etc.
Whoever reads the Roman historians[14] must be surprised at the number of prodigies which are constantly recorded, and which frequently filled the people with the most dreadful apprehensions. It must be confessed, that some of these seem altogether supernatural; while much the greater part only consist of some of the uncommon productions of nature, which superstition always attributed to a superior cause, and represented as the prognostication of some impending misfortunes. Of this class may be reckoned the appearance of two suns, the nights illuminated by rays of light, the views of fighting armies, swords, and spears, darting through the air; showers of milk, of blood, of stones, of ashes, of frogs, beasts with two heads, or infants who had some feature resembling those of the brute creation. These were all dreadful prodigies, which filled the people with inexpressible astonishment, and the Roman Empire with an extreme perplexity; and whatever unhappy circumstance followed upon these, was sure to be either caused or predicted by them.[15]
