Rose Cross and Masonry’s Tau
The Tau makes its appearance as a symbol even in the following centuries, especially in the esoteric field. For example, in the “Fama Fraternitatis”, the first manifestation of the Rosa-Croce movement, first appeared at Cassel in 1614, tells of the find of the tomb of the eponymous father, Christian Rosencreutz, by some brethren . At the center of the tomb there was a round altar covered with a copper plate on which the following inscription was engraved: “Hoc Universe compendium nisus mihi sepulcrum fuit” (“I reserved for this sepulcher the compendium of the Universe“). Under the altar, another copper plate covered the body of the epic, which was found intact, with a scroll of gold parchment written in his hand and titled “T”: it is called “our most Great treasure after the Bible and should not be lightly exposed to the censorship of the world. “
Within the framework of Freemasonry, the form of this letter invokes two tools of masonry, the stonecutter hammer and the double-angle team. But as a symbol it assumes its highest meaning in the Emblem of the Royal Arch, where it appears in the form of “Triple Tau”. This glyph, inscribed in an equilateral triangle and in a circle, is considered a sacred symbol for excellence, which for Jung represents in the collective unconscious the delimitation of the sacred scope and fixation on a universal spiritual center. It was originally a Tau superimposed on an H, to signify “Templum Hierosolymae” (Temple of Jerusalem), thus acquiring its own symbolic autonomy.
