16. It is devoutly to be hoped, for the patients' sake, that treatments like these took effect on the disease, for they got no other. Diseases being conceived as personal demons who entered a man's body of their own accord or under compulsion from powerful sorcerers, and illness being consequently considered as a kind of possession, clearly the only thing to do was to drive out the demon or break the spell with the aid of the beneficent Ea and his son. If this intervention was of no avail, nothing remained for the patient but to get well as he could, or to die. This is why there never was a science of medicine in the proper sense in Chaldea, even as late as three or four hundred years B.C., and the Greek travellers who then visited Babylon must have been not a little shocked at the custom they found there of bringing desperately sick persons out of the houses with their beds and exposing them in the streets, when any passer-by could approach them, inquire into the disease and suggest some remedy--which was sure to be tried as a last chance. This extraordinary experiment was of course not resorted to until all known forms of conjuration had been gone through and had proved inefficient. 17. The belief that certain words and imprecations could break the power of demons or sorcerers must have naturally led to the notion that to wear such imprecations, written on some substance or article, always about one's person must be a continual defence against them; while on the other hand, words of invocation to the beneficent spirits and images representing them, worn in the same way, must draw down on the wearer those spirits' protection and blessing. Hence the passion for talismans. They were of various kinds: strips of stuff, with the magic words written on them, to be fastened to the body, or the clothes, or articles of household furniture, were much used; but small articles of clay or hard stone were in greater favor on account of their durability. As houses could be possessed by evil spirits just as well as individuals, talismans were placed in different parts of them for protection, and this belief was so enduring that small clay figures of gods were found in Assyrian palaces under thresholds--as in the palace of Khorsabad, by Botta--placed there "to keep from it fiends and enemies." It has been discovered in this manner that many of the sculptures which adorned the Assyrian palaces and temples were of talismanic nature. Thus the winged bulls placed at the gateways were nothing but representations of an Accadian class of guardian spirits,--the _Kirubu_, Hebrew _Kerubim_, of which we have made _Cherub_, _Cherubim_--who were supposed to keep watch at entrances, even at that of the Arali, while some sculptures on which demons, in the shape of hideous monsters, are seen fighting each other, are, so to speak, imprecations in stone, which, if translated into words, would mean: "May the evil demons stay outside, may they
