The Rosicrucian Order, I think this order is much older...
For beginnings of Rosicrucianism are considered to be the Egyptian mystery schools, which were made available to the public by Thutmose III (1486 - 4 March 1425 BC)??.
The Rosicrucian Order as a secret brotherhood dates back to AD 46. It was created by the fusion of the "magical" traditions of Ancient Egypt and !Christian teachings?! The Alexandrian Orm is also mentioned in this context. This is why the Library of Alexandria was secretly looted, moved and then set on fire so that no one would look for the books, scrolls and tablets.
I know there is some connection between the Rosicrucians, Templar Order, the Brotherhood of the Serpent, the Babylonian Brotherhood . All have their origins in ancient Egypt.

High-ranking priestesses had a snake tattooed on the front of their left shoulder, and after their death a strip of tattooed skin was cut out and kept. They were initiated at the age of 12, if they pass the tests..

The only positive thing about it is that the OctagonTemplars were created by betraying the original Templars (it happened between the First and Second Crusades), who, on the other hand, had the task of protecting the pure human bloodline until the "end of time" for The Last Judgement.This original mission of the pure Templars was inherited only through the male line from generation to generation, including the training regarding the possibilities of protecting the "God Line" known as the "Holy Grail", which, on the other hand, is inherited only through the female bloodline.These original bloodlines of the pure Templars infiltrated inside and continued to protect the Holy Grail.They are all over Europe and many of them have died because of it.Pure Templars to infiltrate the highest ranks of the Freemasons and functioned as their librarians-it was an insurance policy if something happened, for future generations..and they got "them",it was infiltration in infiltration.
