The megaliths of the world are monuments to revolutionary processes spanning centuries and millenia. The most defining of these is probably the agricultural revolution, which upended the very fabric and foundation of earlier human existence.
When this cist at Södra Härene was built, the people of what would much later be called Sweden had long since begun the process toward organized civilization and sedentary life. They had to a large degree left their hunting-gathering ways and had begun to form farming communities. These communities were prerequisites for building the monumental graves of the Neolithic, as they demanded collective efforts and long-term planning to a degree seldom achieved in the smaller nomadic tribes of the Paleolithic.
As we humans took this step toward permanent settlement, we also left a number of other things behind; we used to regard ourselves as part of nature, but we came to think of ourselves as apart from nature. We used to regard the world and everything in it as inhabited by spirits, animas, which had to be appeased, respected and bargained with, but we came to see ourselves as ruled by almighty deities of which we were mortal likenesses and designated deputies.

_"And the serpent said unto the woman, Ye shall not surely die:
