I, as probably many of you, have been uncovering all of the secret codes in Assassin's Creed 2 that are hidden in the various glyphs. Some are written in binary code, some in hexadecimal code, and another which I have figured out to be Freemason code
A few signs of the Rosicrucian Order( the Order of the Rosy Cross). Many are similar to those of Freemasonry and other secret societies. The penalty sign related to having one's throat cut is shown at number X.
