التضحية البشرية
Many cultures show traces of prehistoric human sacrifice in their mythologies and religious texts, but ceased the practice before the onset of historical records. Some see the story of Abraham and Isaac (Genesis 22) as an example of an etiological myth, explaining the abolition of human sacrifice. The Vedic "Purushamedha" (literally "human sacrifice") is already a purely symbolic act in its earliest attestation. According to Pliny the Elder, human sacrifice in ancient Rome was abolished by a senatorial decree in 97 BCE, although by this time the practice had already become so rare that the decree was mostly a symbolic act. Human sacrifice once abolished is typically replaced by either animal sacrifice, or by the mock-sacrifice of effigies, such as the Argei in ancient Rome.
