(M121) Strange as it may seem to us, one motive which induces a savage warrior to eat the flesh or drink the blood of the foe whom he has slain appears to be a wish to form an indissoluble covenant of friendship and brotherhood with his victim. For it is a widespread belief among savages that by transfusing a little of their blood into each other’s bodies two men become kinsmen and allies; the same blood now circulating in the veins of both, neither can injure the other without at the same time injuring himself; the two have therefore given each other the strongest bond, the best possible hostages, for their good behaviour.(480) Acting on this theory, the primitive warrior seeks to convert his slain foe into the firmest of friends by imbibing the dead man’s blood or swallowing his flesh. That at all events appears to be the idea at the root of the following customs. When an Arawak Indian of British Guiana has murdered another, he repairs on the third night to the grave of his victim, and pressing a pointed stick through the corpse he licks off and swallows any blood that he finds adhering to the stick. For he believes that if he did not taste his victim’s blood, he would go mad and die; whereas by swallowing the blood he averts any ill consequences that might flow to him from the murder.(481) The belief and practice of the Nandi are similar: “To the present day, when a person of another tribe has been slain by a Nandi, the blood must be carefully washed off the spear or sword into a cup made of grass, and drunk by the slayer. If this is not done it is thought that the man will become frenzied.”(482) So among the tribes of the Lower Niger “it is customary and necessary for the executioner to lick the blood that is on the blade”; moreover, “the custom of licking the blood off the blade of a sword by which a man has been killed in war is common to all these tribes, and the explanation given me by the Ibo, which is generally accepted, is, that if this was not done, the act of killing would so affect the strikers as to cause them to run amok among their own people; because the sight and smell of blood render them absolutely senseless as well as regardless of all consequences. And this licking the blood is the only sure remedy, and the only way in which they can recover themselves.”(483) Among the Shans executioners believe that they would soon fall ill and die if they did not taste the blood of their victims.(484)
