Book excerpt: A Monitor or Guide to the rituals, ceremonies, instructions, and symbolism of all the degrees of the Ancient and Accepted Scottish Rite written by Charles T. McClenachan, 33°, Grand Master of Ceremonies of the Supreme Council for the Northern Masonic Jurisdiction of the Ancient and Accepted Scottish Rite. This work offers an unprecedented level of detail concerning the rituals associated with each degree. McClenachan, contemporary of Albert Pike, provides here a valuable glimpse into some of the elements of Scottish Rite ritual that predate Pike’s revisions and expansions, as various ceremonies such as the Lodge of Sorrow, Ceremony of Baptism in the AASR, Installation of Officers as well as a Masonic Glossary, the Grand Constitutions of 1786, Forms of the Scottish Rite, and much more.
