Philo of Alexandria. You won't find "Philo" much less, "Philo of Alexandria" in "The Tunnel Thru the Air." Wait, yes you will. You will find the letters 'philo' in the word 'philosopher (y)' some 7 times. Do a word count of "philo" in TTTTA.
Philo, a first century philosopher was a student of the works of Pythagoras and Plato. He developed a system of writing and teaching that relied on what one site refers to as Philo's enigmas (see HERE). Enigmas contrasted from allegory. The latter, I am informed, relies upon the reader's interpretation where the former is so constructed to force the reader to understand the authors meaning.
Among the rules of Philo's enigma (according to the above link) you will find such devices as number 12 from the above link; any peculiarity of a phrase. Perhaps the misspelling of the word "Mammouth" to bring attention to the 110-structure so reminiscent of the ill fated World Trade Center? Or (1), the repetition of a phrase....perhaps the repetition of Mathew 7:7 (ask, seek, knock) three times in TTTTA, each time less formally. Or the many repetitions of the adaption of Mathew 9:29 in Marie's mysterious letter of disappearance; "...according to your faith be I unto you."
I would submit the rule of greatest importance and one that is inversely proportionate to its use is that the greatest concepts are not stated. They are taught by their absence and the toil that must be undertaken to uncover their meaning.
You won't find "philo" in TTTTA, but that doesn't mean his work was employed therein. If you work with the rules of enigma in the above link, you'll find them used in TTTTA. But the greatest truths, in my opinion, will be the ones that you must deduce. And it won't be easy; an allegory is easy to understand but the understanding you receive might not be the one the author intends. The enigma is difficult to discover, the details difficult to evaluate and qualify, but the result is far closer to the intent of the author. At least, that is how I understand the nature of the methods of Philo.
Lord Francis Bacon, mentioned once in the plain wording of TTTTA in the second paragraph of Chapter XXII on page 126, declares, while holding a Bible up, "There God speaks." The inversely proportionate meaning one might infer from Philo; Lord Francis Bacon is very important to Mr. Gann and the meaning of TTTTA.
Consider, Lord Bacon was a master cryptographer for his day (1561-1626). Well, do we find TTTTA filled with acrostic and telestic encoding? Indeed. Those who partake only of milk might contest that but the occurrence of meaningful 6 letter words spelled in acrostics and telestics defies Eddington's "army of monkeys."
Lord Bacon was a spiritualist.
I'll let the noteworthy Lord Francis Bacon sit for the moment.
John Dee, the mathematician, alchemist, scholar, geometer, astrologer, magician of the court of Queen Elizabeth I. Dee was reputed to have owned more than 4,000 volumes in his personal library at a time when Cambridge library contained less than 400. He was also a great cryptographer and communicated with QE I in code. His signature in encrypted messages to QE I was "007." You will not find John Dee in the plain narrative of TTTTA once. Not once. But you find him 45 times (interesting, 45) in the telestic encoding. I'll give you the first, last and middle or 23rd occurrence:
There you have it. "Dee" is spelled 44 times and "007" is spelled once. And it so happens "007" is the exact midpoint of the those 45 items. And if you look at the line number, it is cumulative line number 7579 out of 15340 lines. Nearly exactly the midpoint of TTTTA in lines. I expect it is the exact midpoint but the above is an early count of the lines in the book. I expect Mr. Gann is correct and Jim is not correct so I'm not all that hot on fixing what I know is my error when I have other things to do.
John Dee was very important. Jim Egan, curator of the Newport Tower in Newport RI has researched and written extensively on John Dee (HERE). Aside from the symbolism of Dee's work, Mr. Egan derives what he calls Dee's "philosopher stone number," the number 252. Remember that number.
As an aside I have named the number 432, WD Gann's philosopher stone number, because there are 432 pages in TTTTA including the covers and blank pages. When we look at those two numbers as a ratio of 432 / 252 we can reduce it to 12 / 7; two of Mr. Gann's favorite numbers. Two numbers that highlight some great Bible verses.
Sherlock Holmes, a fictional detective created by Sir Arthur Conan Doyle who was cameo'd twice in TTTTA. Modestly important by Philo's rules (mentioned only twice in TTTTA) but I'll offer an observation made by Holmes that might be interesting:
Yes, Sir Arthur was quite the spiritualist.
And WD Gann, quite a spiritualist as well. I like to think of the just over 12 books published by Roger Brothers as the real WD Gann reading list. It includes a Bible prophecy author (Thomas Troward, "Bible Prophecy..."), a book on Pythagorean numerology ("The Ancient Science of Numbers"), a book on very deep philosophy and spiritualism by Judge David Hatch ("The Straight Goods on Philosophy"), and a number of books on really deep symbolic, religious spiritualism. In TTTTA we have a number of tales about spiritual experiences and Maries mysterious appearance in France. All things are circular....
All of the above to what end?
WD Gann was born in 1878, 252 years after Lord Francis Bacon passed in 1626.
Not buying the implication? I wouldn't either had I not had the experience explained HERE. As it is, I will not discount the suggestion.
Gosh, I've written all this and I now find out Francis Bacon was actually reincarnated as a particularly distinguished individual who is found HERE.
