Chas S. Clifton, an academic scholar of Neopaganism, made several suggestions as to where the early RDNA founders may have got their ideas about Druidry from, noting that there were British Druid groups such as the Ancient Druid Order operating at the time, who held annual ceremonies at the megalithic monument of Stonehenge in Wiltshire, attracting much media attention. Accompanying this, there were ideas about the ancient druids to be found in the "American literary consciousness", where they appeared as guardians of the natural world in the Romanticist poetry of Philip Freneau.
