Babylonian sorcery, whether legitimate or illegitimate, was intended to work upon or through demons; and its familiarity with the names and special qualities of demons is its peculiar mark. In the ritual of exorcism of the demons, idols play a prominent and often singular rôle. The following performance is probably unique: in the exorcism of disease two idols, male and female, were set up before the sick man, then the evil spirits of sickness are invited thus: “Oh ye all wicked, all evil, who pursue so-and-so, if thou art male, here is thy wife; if thou art female, here is thy husband.”[297.2] The intent of the exorciser seems to be to attract the demon of disease, of whose sex he is not sure, into one or the other of these images, and he lures it by amorous enticement into the figure of opposite sex to its own; {298} having got the demon into the image, he doubtless takes it out and burns or buries it. Or the evil spirit may be attracted from the patient by means of its own image placed near him. One document prescribes various images of bestial form, all of which are to be taken by night to the bank of the river, probably that they may be thrown in and carry the impurity of sickness away.[298.1] Another shows us how to deal with Labartu, the daughter of Anu;[298.2] her image, made of clay, is placed above the head of the sick man, so as to draw her or her power out from him; it is then taken out, slain, and buried. And this exorcism is all the more notable because Labartu is rather an evil goddess than a mere demon, being styled in another text “August lady,” “Mistress of the dark-haired men.”[298.3] Such magical drama, in which the demon-image might be slain to annul its potency, seems characteristically Babylonian: it entered also into the ritual of the high gods. For, at the feast of the New Year, when Nebo arrived from Borsippa, two images are brought before him and in his presence decapitated with the sword. Dr. Langdon interprets them[298.4] as representing probably “the demons who aided the dragon in her fight with Marduk; they are the captive gods of darkness which ends with the Equinox.” This is dramatic magic helpful to the gods. The elaboration of exorcism must have led to a minuter articulation of the demon-world; the exorciser is most anxious to know and discover all about his unseen foes: he gives them a name, a sex if possible, and a number: he says of the powerful storm-demons {299} Utuk “they are seven, they are seven, they are neither male nor female, they take no wife and beget no children;”[299.1] for knowledge of the name or nature of the personality gives magic power.
