1954-1955. This collection contains WD Gann's most rare writings, those on financial astrology.

Many people speculate and argue about just how key astrological work was to Gann's full system, as there is very little direct evidence or outright explanation of how he used astrology. Most of his references were contained in his coded book The Tunnel Thru the Air, and aside from that book, there is nothing but a handful of references where he directly discusses astrological techniques and tools in his work. This collection contains everything known from Gann's work where he presents astrological ideas, charts, tools or letters of any kind.

First is an early course from 1921, the first place he mentions a planetary correlation with his time cycles. Next is an interesting piece on the Human Body which contains astrological correlations and symbolism connected to Time Cycles. We then include some letters to students where he quite openly discusses some of his techniques related to astrology. Finally, there is a set of charts with clear planetary elements, applications and tools. This is an important course which reveals some of the great WD Gann's most secret teachings.
