Human sacrifice is attributable to the most forbidding customs of ancient tribes. Among Asian and European cultures, it permeated unevenly. The Greek myths speak of human sacrifice but historical sources provide no data of any actual practice of the kind. In the ancient Greece, it was considered an old yet no longer exercisable rite replaced by the sacrifice of animals. Although the gladiator fights point to the fact that the Romans enjoyed terrifying shows, neither can they be associated with the human sacrifice as a common feature of their customs.
