Thank you very much! I am glad you find it interesting.
First to your question. Many think that the Zodiac mis-spelled words are intentional, an attempted misdirection on his part. Zodiac spelled many complex words correctly, like "ammonium nitrate", "fertilizer", "system" and many others. Yet he he also gave us "cid" for "kid" and many other wrongly spelled easy words. It seems an attempt to make detectives think he is uneducated. Remember also that Zodiac devised codes that the FBI and the military failed to break.
Ted Kaczynski used a similar misdirection as the Unabomber. He sent a letter to a prior victim Prof. Gerlernter, who had written in a book that 'anyone with a college degree can learn computers'. Kaczynski wrote him as the Unabomber and said (from memory) 'what about the rest of us? I suppose those wothout degrees don't coun't'. Ted recorded in his journal that this would make investigators think the Unabomber did not have a college degree - in fact Ted had a degree from Harvard and a PHD from Michigan, but the FBI profile said the Unabomber was likely an angry and undeducated airline mechanic.
Thank you for your information on "THEO" and "DEO". I personally think the most likely explanation for their appearance in the code is that "THEO" is the first four letters in the name "THEODORE", while "DEOR" has the last four. But in fairness I thought I should note that "THEO" is Greek for GOD and "DEO" Latin for GOD. I also thought it could be a double play, i.e., getting his name in there (to satisfy his ego) but also with a valid alternate explanation (God theme obscures true meaning). Your information puts a slightly different spin on it, so I will have to research that issue some more.
Is it not true that in a word like THEOLOGY, the prefix THEO means God or Diety? And while the Greeks believed in multiple Gods, assuming monotheism, would THEO be a rough translation as GOD?
Thanks again for the information.
