Ancient Divination Through Human Sacrifice
Anthropomancy is an archaic form of fortune-telling that relied on examining the internal organs of human victims. Practitioners believed that reading these entrails could reveal secrets of the future.
While many ancient cultures practiced divination using animal organs, this specific method involved killing humans to inspect their remains for prophetic signs. It was considered a fringe and extreme practice even during the height of the Roman era. Most mainstream rituals typically relied on livestock like sheep to avoid the consequences of such grim methods. This practice remains one of history's darkest examples of seeking divine insight.
