Describe symbolism in Holy Blood, Holy Grail by Michael Baigent

Rose croix means red or rose cross. The rose cross is an important symbol to the Priory of Sion. It is so important that the Priory of Sion once referred to themselves as l'Ordre de la Rose-Croix Veritas. It is also said that Ormus gave this identifying symbol to his order of initiates. There is also a society called the Rosicrucians, which is believed to have roots in ancient history.
