Aubrrey Burl cites instances of primitive people affecting the fertility of the land and crop harvest by performing sexual intercourse with animals and each other, within the megalithic enclosures. "Much early religion was naturalistic, concerned with nature and its effects, sometimes requiring a shaman to intercede with nature on behalf of the community, less a witch-doctor than a medium who would dance himself into a drum-beaten ecstasy before passing into a trance." (Burl, Aubrey. The Stone Circles of the British Isles. New Haven: Yale UP, 1976. 87-88.)
