It may be asked, wherefore was this elaborate cleanliness essential to avoid taboo? The answer undoubtedly is—because of the belief in the power of sympathetic magic. Did one come into contact with a person who was in any way unclean, or with a corpse or other unpleasant object, he was supposed to come within the radius of the evil which emanated from it.
Popular Superstitions
The superstition that the evil-eye of a witch or a wizard might bring blight upon an individual or community was as persistent in Chaldea as elsewhere. Incantations frequently allude to it as among the causes of sickness, and exorcisms were duly directed against it. Even to-day, on the site of the ruins of Babylon children are protected against it by fastening small blue objects to their head-gear.
Just as mould from a grave was supposed by the witches of the Middle Ages to be particularly efficacious in magic, so was the dust of the temple supposed to possess hidden virtue in Assyria. If one pared one's nails or cut one's hair it was considered necessary to bury them lest a sorcerer should discover them and use them against their late owner; for a sorcery performed upon a part was by the law of sympathetic magic thought to reflect upon the whole. A like superstition attached to the discarded clothing of people, for among barbarian or uncultured folk the apparel is regarded as part and parcel of the man. Even in our own time simple and uneducated people tear a piece from their garments and hang it as an offering on the bushes around any of the numerous healing wells in the country that they may have journeyed to. This is a survival of the custom of sacrificing the part for the whole.
If one desired to get rid of a headache one had to take the hair of a young kid and give it to a wise woman, who would "spin it on the right side and double it on the left," then it was to be bound into fourteen knots and the incantation of Ea pronounced upon it, after which it was to be bound round the head and neck of the sick man. For defects in eyesight the Assyrians wove black and white threads or hairs together, muttering incantations the while, and these were placed upon the eyes. It was thought, too, that the tongues of evil spirits or sorcerers could be 'bound,' and that a net because of its many knots was efficacious in keeping evilly-disposed magicians away.
Omens
Divination as practised by means of augury was a rite of the first importance among the Babylonians and Assyrians. This was absolutely distinct from divination by astrology. The favourite method of augury among the Chaldeans of old was that by examination of the liver of a slaughtered animal. It was thought that when an animal was offered up in sacrifice to a god that the deity identified himself for the time being with that animal, and that the beast thus afforded a means of indicating the wishes of the god. Now among people in a primitive state of culture the soul is almost invariably supposed to reside in the liver instead of in the heart or brain. More blood is secreted by the liver than by any other organ in the body, and upon the opening of a carcase it appears the most striking, the most central, and the most sanguinary of the vital parts. The liver was, in fact, supposed by early peoples to be the fountain of the blood supply and therefore of life itself. Hepatoscopy or divination from the liver was undertaken by the Chaldeans for the purpose of determining what the gods had in mind. The soul of the animal became for the nonce the soul of the god, therefore if the signs of the liver of the sacrificed animal could be read the mind of the god became clear, and his intentions regarding the future were known. The animal usually sacrificed was a sheep, the liver of which animal is most complicated in appearance. The two lower lobes are sharply divided from one another and are separated from the upper by a narrow depression, and the whole surface is covered with markings and fissures, lines and curves which give it much the appearance of a map on which roads and valleys are outlined. This applies to the freshly excised liver only, and these markings are never the same in any two livers.
Certain priests were set apart for the practice of liver-reading, and these were exceedingly expert, being able to decipher the hepatoscopic signs with great skill. They first examined the gall-bladder, which might be reduced or swollen. They inferred various circumstances from the several ducts and the shapes and sizes of the lobes and their appendices. Diseases of the liver, too, particularly common among sheep in all countries, were even more frequent among these animals in the marshy portions of the Euphrates Valley.
