In Royal Arch Masonry, several significant symbols are utilized, each carrying deep meanings. One of the most prominent symbols is the Triple Tau, which is formed from three levels, representing the unity of the Divine as Father-Mother. This symbol also signifies the crucifixion of the Divine Life in the world of manifestation and embodies the androgynous nature of the Deity. The Triple Tau is often referred to as the Key, which is used as a measure or mnemonic for calculating the Platonic Solids, symbolizing various elements such as Fire, Air, Earth, and Water.
Additionally, the Four Living Creatures are depicted in the Royal Arch, representing the tribes of Ephraim, Judah, Dan, and Reuben, and are associated with the astrological signs of Taurus, Leo, Scorpio, and Aquarius, respectively. These creatures are often illustrated on a heraldic shield, crested by the Ark of the Covenant.
Other symbols include the Circle and Triangle, which represent the Divine's manifestation and the interplay of the masculine and feminine aspects of God. The Rose symbolizes love, secrecy, and fragrance, while the Cross signifies self-sacrifice, immortality, and holiness. Together, these symbols convey profound teachings about the nature of the Divine and the universe.
