These examples prove that the eating of a sacred animal is often believed to produce leprosy or other skin-diseases; so far, therefore, they support the view that the pig must have been sacred in Egypt, since the effect of drinking its milk was believed to be leprosy.
Again, the rule that, after touching a pig, a man had to wash himself and his clothes, also favours the view of the sanctity of the pig. For it is a common belief that the effect of contact with a sacred object must be removed, by washing or otherwise, before a man is free to mingle with his fellows. Thus the Jews wash their hands after reading the sacred scriptures. Before coming forth from the tabernacle after the sin-offering, the high priest had to wash himself, and put off the garments which he had worn in the holy place. It was a rule of Greek ritual that, in offering an expiatory sacrifice, the sacrificer should not touch the sacrifice, and that, after the offering was made, he must wash his body and his clothes in a river or spring before he could enter a city or his own house. The Polynesians felt strongly the need of ridding themselves of the sacred contagion, if it may be so called, which they caught by touching sacred objects. Various ceremonies were performed for the purpose of removing this contagion. We have seen, for example, how in Tonga a man who happened to touch a sacred chief, or anything personally belonging to him, had to perform a certain ceremony before he could feed himself with his hands; otherwise it was believed that he would swell up and die, or at least be afflicted with scrofula or some other disease. We have seen, too, what fatal effects are supposed to follow, and do actually follow, from contact with a sacred object in New Zealand. In short, primitive man believes that what is sacred is dangerous; it is pervaded by a sort of electrical sanctity which communicates a shock to, even if it does not kill, whatever comes in contact with it. Hence the savage is unwilling to touch or even to see that which he deems peculiarly holy. Thus Bechuanas, of the Crocodile clan, think it hateful and unlucky to meet or see a crocodile; the sight is thought to cause inflammation of the eyes. Yet the crocodile is their most sacred object; they call it their father, swear by it, and celebrate it in their festivals.
The goat is the sacred animal of the Madenassana Bushmen; yet to look upon it would be to render the man for the time impure, as well as to cause him undefined uneasiness. The Elk clan, among the Omaha Indians, believe that even to touch the male elk would be followed by an eruption of boils and white spots on the body. Members of the Reptile clan in the same tribe think that if one of them touches or smells a snake, it will make his hair white. In Samoa people whose god was a butterfly believed that if they caught a butterfly it would strike them dead. Again, in Samoa the reddish-seared leaves of the banana-tree were commonly used as plates for handing food; but if any member of the Wild Pigeon family had used banana leaves for this purpose, it was supposed that he would suffer from rheumatic swellings or an eruption all over the body like chicken-pox. The Mori clan of the Bhils in Central India worship the peacock as their totem and make offerings of grain to it; yet members of the clan believe that were they even to set foot on the tracks of a peacock they would afterwards suffer from some disease, and if a woman sees a peacock she must veil her face and look away. Thus the primitive mind seems to conceive of holiness as a sort of dangerous virus, which a prudent man will shun as far as possible, and of which, if he should chance to be infected by it, he will carefully disinfect himself by some form of ceremonial purification.
