A fascinating book on Symbolism and Astrology of Freemasonry first published in 1923.

“Away back in 1887, when the city of Alpena was located in the heart of one of the lumber districts of Michigan, Hopper Lodge, U. D. (now No. 386), of that city was pleased to honor me with membership in due and ancient form.

“In those days, or at least in that Lodge, there was no horseplay; and I was so impressed with the work that I resolved to master all the lectures, which I did. The part which interested me the most was the one which I could learn the least about. I would have sacrificed a five-dollar note to learn why Pythagoras sacrificed a hecatomb, and would have given as much to anyone who would explain the mystery surrounding the 47th Problem of Euclid, as depicted on the lecture chart. When inquiry failed me, I made diligent search and finally discovered the KEY OF THE HOUSE OF DAVID, through the knowledge of which I was enabled to penetrate the allegorical veil, just as Pythagoras did five hundred years before the Christian era.

“On the night of my initiation I was told that Freemasonry was founded on the Bible, and all its secrets were hidden therein. In my research work I discovered that the true secrets of Freemasonry were written in the stars and the book of nature, and a knowledge of astronomy and astrology was necessary to lift the allegorical veil. Upon obtaining this knowledge I discovered that the Bible was founded upon the same law as Freemasonry, i.e., the stars and the book of nature.”—Author’s Foreword
