Anthropomancy
From Academic Kids
Anthropomancy (from Greek anthropos, 'man', and manteia, 'divination') is a method of divination by the entrails of dead or dying men or women, through sacrifice. This practice was sometimes also called Splanchomancy (divination by examining the entrails of sacrificial victims).
Heliogabalus (the Roman emperor Varius Avitus Bassanius, 205-221) and the ancient Egyptians were known practitioners of this type of divination.
