Book excerpt: Publication of a research work to Rudolf Steiner's statements and scetches on the planets' lemniscatory paths. For the first time in almost a hundred years, Rudolf Steiner's statements and sketches on the subject of the "Lemniscatory paths of the planets", distributed over several lecture cycles, have been brought into a larger context and examined for the consequences of this. Steiner's suggestions for a new consideration of the planetary movement were taken up and tried to develop them further in the given sense. The work "The Lemniscatory Path System" arose from this. The treatise comprises 192 pages with 253 mostly coloured illustrations.
