What is the meaning of the phrase lettered bt tigattogr? The phrase appears to be a misspelling or misinterpretation of "lettered by Tigrattogr." In Freemasonry, this likely refers to the concept of being "lettered by the Tetragrammaton," which is a significant term in Masonic symbolism. The Tetragrammaton, represented by the four Hebrew letters YHVH, is often translated as "Jehovah" or "Yahweh" and symbolizes the Divine Being, the Great Architect of the Universe. To be "lettered by the Tetragrammaton" implies receiving instruction or enlightenment from the divine principles and wisdom that this name embodies. This aligns with Freemasonry's emphasis on moral and spiritual development, as it seeks knowledge and understanding of the Divine.
