Albin Grau, Gate drawing, published in Saturn Gnosis Magazine , before 1930
The magazine was from a group interested in the teachings of the Fraternitas Saturni, or Brotherhood of Saturn, a German occult group dating from about 1930 and continuing after World War II. One essential feature of the Gnosis was the sex-magic adjustment of coital positions to match planetary movements. The last issue was published in 1930, the Berlin order disbanded not long afterwards, due to the prohibition imposed by Nazi Germany on the esoteric societies. Grau would die at Buchenwald concentration camp in October, 1942
