The most conclusive evidence that the bogmen were sacrificed is the story their bodies tell of the manner of their deaths. Each submitted himself naked to an elaborate, ritualized Triple Death. In the case of Lindow Man, for instance, his skull was flattened by three blows of an ax, this throat garroted by a thrice-knotted sinew cord, his blood emptied quickly through the precise slitting of his jugular. Here is the ancient victim of sacrifice, the offering made out of deep human need. Unblemished, raised to die, possibly firstborn, set aside, gift to the god, food of the god, balm for the people, purification, reparation for all – for sins known and unknown, intended and inadvertent. Behold god’s lamb, behold him who takes away the sins of all.
Patrick declared that such sacrifices were no longer needed. Christ had died once for all.Cahill, How the Irish Saved Civilization, p. 140
