Green Egg was created by Oberon Zell-Ravenheart, who was the editor from 1968 to 1974. It started as a one-page ditto sheet. It continued under another editor for two more years, by which point it had grown over 80 issues into a 60-page journal. According to J. Gordon Melton in the Encyclopedia of American Religions, it became "the most significant periodical in the Pagan movement during the 1970s and made Oberon Zell-Ravenheart, its editor, a major force in Neo-Paganism". It became dormant in 1976.
