In volume I of “A History of Religious Ideas”, Mircea Eliade opens on page 5 with explanation of a ritual of “mystical solidarity” from the Stone Age, that I have not read anywhere else.
In this ritual hunter-gatherers see the blood of the prey as similar in every respect to their blood; and by killing the prey they identify themselves with their prey for two reasons. They seek redemption for the sin of killing their prey, and they identify with their prey to maintain their unique system of survival for both hunter and prey. This ritual – altered, revalorised and camouflaged – is still within our modern society.
This paragraph shed a different light on the many kinds of charity that captains of industry perform in the later part of their life.
This first volume continues with an abundance of religious developments of mankind in the Indo-European society until the Dionysiac festivals.
A must read to get an overview of the religious ideas with one remark: ideas unknown to me are covered in depth, but religious ideas that I have studied before, are described more superficial; but this remark says more about me as a reader than about the content of the book.
