This is a work of Masonic history and speculative mythology, written in an expository, scholarly-adjacent tradition common to 19th-century fraternal literature. The author argues for a grand unified genealogy of Freemasonry tracing its origins to Noah after the biblical flood, through which speculative (philosophical/spiritual) traditions were preserved by some descendants while others fell into polytheism and idol worship. A central claim is that two distinct ancient streams — "Primitive Freemasonry" among Israelites and "Spurious Freemasonry" among Gentile mystery cults, including the Dionysiac Artificers of Tyre — merged at the construction of Solomon's Temple, producing the first union of speculative and operative (practical craft) Masonry. The author also argues that Pythagoras was initiated into Temple Masonry during the Babylonian captivity, explaining his philosophical closeness to Masonic principles. The stated goal is not comprehensive history but an interpretive framework for understanding Masonic symbolism through the lens of these foundational moments. Readers interested in the ideological self-construction of 19th-century Freemasonry, or the use of biblical and classical history to legitimize fraternal institutions, will find this a representative and earnest example of that genre.
