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.(202) 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.(203) 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 sacred contagion. For example, in Tonga a man who happened to touch a sacred chief, or anything personally belonging to him, as his clothes or his mat, was obliged to go through the ceremony of touching the soles of the chief’s (or of any chief’s) feet with his hands, first applying the palm and then the back of each hand; next he had to rinse his hands in water, or, if there was no water near, the sap of the plantain or banana-tree might be used as a substitute. If he were to feed himself with his hands before he performed this ceremony, it was believed that he would swell up and die, or at least be afflicted with scrofula or some other disease.(204) We have already seen what fatal effects are supposed to follow, and do actually follow, from contact with a sacred object in New Zealand.(205) 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.(206) 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.”(207) 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.(208) 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.(209) In Samoa people whose god was a butterfly believed that if they caught a
