delighted in human sacrifice; and at their altars, hundreds, if not thousands, of hopeless war-captives and innocent children were annually devoted to slaughter in the belief that, unless the gods were nourished and rejuvenated with the blood of human beings, they would droop into senility and perish, with the result that the world would be wrapped in darkness and the human race become extinct. The festivals in connection with the cults of the numerous Aztec gods were many, and involved the practice of an imposing and bewildering ritual, the climax to which was only too often an orgy of cannibalism, which was rendered none the less abhorrent in that it was surrounded by the circumstances of a degree of civilisation by no means despicable.
