The compound character known as the triple tau is one of the Royal Arch’s emblems. A triple tau is literally “three Tau’s,” the tau being the nineteenth letter in the Greek Alphabet. The triple tau of Royal Arch Masonry consists of 3 Ts linked in the centre joined at their base. This mystical character can be signified in a few different ways. First, the names Hiram of Tyre and Hiram Abif appear in the Phoenican language with the same letters “H” and “T” as they do in English. Therefore, the Triple Tau takes on the interpretation of the initial letters in Hiram Abif’s name. http://freemasonry.bcy.ca/symbolism/triple_tau.html
