I have very different findings than most from my research. Magdalene means Great, a royal title for an imperial monarch who had influence on the world in a big way. eg. Catherine the Great. (I'm technically a royal by blood, so got some training on this stuff as a little girl.) History books and Hollywood movies were changed in the 20th century for political agenda. It only takes one generation to forget.
There is so much crap out there that is overdone or underdone by younger folk who do not know to do the research or try it real life. Including history books, self help commentators, new age gurus, blockchain, and politics. I find myself hanging back and waiting for the good stuff and the truth. Red Pill or Blue Pill?
The truth is written in code in classical art and design. Once you can see it, it is everywhere and it is Googleable, because it is the same history as history books, but rearranged. It also makes it hard to watch or listen to the 20th century version. Sorry, no offense meant. It's a kind of red pill or blue pill situation. You will understand when you learn the code and the truth, no aliens or paranormal involved, just art history and some conspiracies that are still happening today.
Grail, comes from Sangraal, Sacred Blood. It is another name for royalty. The dish is from ritual, but that is a different story, 20th century history mixed them up. The Grail and the Bible are not a Jewish stories, sorry, not meaning to offend, just research. That mythology was made up in the 20th century as part of a program by governments and Hollywood to make Jewish peoples expelled from Europe want to move to Palestine.
True stories are never simple, nor do they have dead ends. The Victorian houses in the Haight may have been designed and decorated by people who didn't know the story and repeated certainly by people who don't know. But the true story of what we today call the Holy Grail was more publicly available 100 years ago.
Back then architects mostly belonged to secret societies, such as the Masons, because that is where they networked for high paid gigs. Dan Brown was correct that the code and alt history does exist, but the story is way more complicated and longer than the Da Vinci Code. I have since completed another 2 years research and another book which fills in a lot more blanks and makes more sense. Titled Coded History Haight Ashbury by DA Hodgson, on Amazon and Blurb, and has lots of photos.
Our school and university history books were edited and Hollywood movies censored in the 20th century. This was to make Jesus Jewish and Palestine seem like the Holy Land, so that Jewish peoples expelled from Europe would want to go there. It only takes one generation to forget. But the real expert on Holy Grail coded art and architecture was Big Alma.
Alma Spreckels, who sponsored the Legion of Honor and other museums in San Francisco and Northern California, which are full of Holy Grail coded art. Big Alma was a total geek on this stuff and her museums, monuments, and art collections are devoted to it in code. Plus all of the other buildings and monuments Alma and friends sponsored, such as St Ignatius cathedral, which is a Knights Templar church and abby overlooking Haight Ashbury. Track the art history of each of the symbols on the Painted Ladies in Haight Ashbury and see for yourself.
Haight Ashbury used to be home to a large Masonic cemetery and USA Knights Templar Commandery No 1. If you are into geomancy you will have fun with a compass and map and the Masonic locations and Big Alma's buildings and monuments. If you have been to Paris France you will notice that Alma's Legion of Honor collections are a miniature version of the Louvre, complete with modern glass pyramid.
There is a code in art and architecture, it is an ancient language only used by royals. It is called Heraldry. I learned it as a little girl and about royal and religious politics, because my family are princes by blood, Church of England, and we have our own family heraldry. It gets more complicated, too much to write here. I wrote a book on it and was taught about royal politics and symbology as a child. http://CodedHistory.com
Dan Brown is correct in that the code and alt history exist and that it takes an art historian to crack it. For example: The arch is a symbol for a few things. One of the sons of the historical people that JC and MM in the Bible were based upon, I think the eldest. Also the tomb of the historical JC, and it is not in the Middle East.
As for my research being blasphemous. I come from a family who has built churches for many centuries and a great uncle was Queen Elizabeth II's favorite priest. First Commandment "For I am a jealous God. Thou shalt worship no other God before me." Which is telling us in no uncertain words that the worship of anybody else as God, including Jesus Christ, is blasphemous.
Plus the letter J was not invented until the 15th century. Research the history of the translations and printings of the Bible. New web site with social media discussion groups, so you can debate it with other researchers, and some free augmented reality games to learn the code ;-) http://CodedHistory.com
