The Royal Arch of Enoch: The Impact of Masonic Ritual, Philosophy, and Symbolism by Robert W Sullivan IV [also] is a book from last year which appears to offer an exploration of the 13th degree of Scottish Rite Freemasonry (of which McClenechan says, “This degree, in fact, forms the climax of Ineffable Masonry” [via]) and its history, but I was especially struck by the part of the description which claims this book “also documents the symbolic restoration of the sun as the premier icon in all of Freemasonry and as the supreme emblem of imperial administration and religiosity lifted from the Ancient Mysteries” as indication the work may be relevant to those interested in Ordo Templi Orientis, not primarily specific to Freemasonry.

“The result of over twenty years of research, Robert Sullivan’s The Royal Arch of Enoch, presents a real life “Da Vinci Code/National Treasure” mystery which, until the publication of this book, was previously unknown to history and historians in both the East and West.

“And Enoch walked with God: and he was not; for God took him.” — Genesis 5:24. The Royal Arch of Enoch: The Impact of Masonic Ritual, Philosophy, and Symbolism documents an undiscovered historical anomaly: how a high degree Masonic Ritual — developed in France in the mid 1700’s — included elements of the Book of Enoch (a/k/a I Enoch) which was considered lost until Freemason and traveler James Bruce returned to Europe with copies from Ethiopia in 1773. These copies were not translated into English until 1821 at Oxford University. This high degree ritual — titled The Royal Arch of Enoch — documents the recovery of the “Lost Word of a Master Mason”, the Name of God.

It is this ritual in particular that has defined, among other things, the American national character. The Royal Arch of Enoch also documents the symbolic restoration of the sun as the premier icon in all of Freemasonry and as the supreme emblem of imperial administration and religiosity lifted from the Ancient Mysteries, incorporated in the Abrahamic faiths, and carried on in both Blue Lodge and High Degree Masonry.” [via]
