metaphysician Georges Gurdjieff. Publications on the Vril Society in German The book of Jacques Bergier and Louis Pauwels was published in German with the title: Aufbruch ins dritte Jahrtausend: von der Zukunft der phantastischen Vernunft (literally Departure into the Third Millennium: The Future of the Fantastic Reason) in 1969. In his book Black Sun, Professor Nicholas Goodrick-Clarke refers to the research of the German author Peter Bahn. Bahn writes in his 1996 essay, "Das Geheimnis der Vril-Energie" ("The Secret of Vril Energy"), of his discovery of an obscure esoteric group calling itself the "Reichsarbeitsgemeinschaft", which revealed itself in a rare 1930 publication Vril. Die Kosmische Urkraft (Vril, the cosmic elementary power) written by a member of this Berlin-based group, under the pseudonym "Johannes Täufer" (German: "John [the] Baptist"). Published by the influential astrological publisher, Otto Wilhelm Barth (whom Bahn believes was "Täufer"), the 60-page pamphlet says little of the group other than that it was founded in 1925 to study the uses of Vril energy. The German historian Julian Strube has argued that the historical existence of the "Reichsarbeitsgemeinschaft" can be regarded as irrelevant to the post-war invention of the Vril Society, as Pauwels and Bergier have developed their ideas without any knowledge of that actual association. Strube has also shown that the Vril force has been irrelevant to the other members of the "Reichsarbeitsgemeinschaft," who were supporters of the theories of the Austrian inventor Karl Schappeller (1875–1947). Esoteric neo-Nazism After World War II, a group referred to by Nicholas Goodrick-Clarke as the Vienna Circle elaborated an esoteric neo-Nazism that contributed to the circulation of the Vril theme in a new context. In their writings, Vril is associated with Nazi UFOs and the Black Sun concept. Julian Strube wrote that a younger generation related to the Tempelhofgesellschaft, has continued the work of the Vienna Circle and exerts a continuous influence on the most common notions of Vril. Those notions are not only popular in neo-Nazi circles but also in movies or computer games, such as Iron Sky, Wolfenstein, and Call of Duty.
