among bacstrom's circle of associates in london were the physician and astrologer ebenezer sibly (1751-ca.1799) and the general charles rainsford (1728-1809). from frederick hockley, bacstrom's writings probably came into the hands of william alexander ayton (1816-1909), william wynn westcott and samuel liddell macgregor mathers, thus influencing the teachings of the hermetic order of the golden dawn, and thus in turn influencing the development of western occultism in the 20th century.
