Latin for Holy of Holies. Every student of Jewish antiquities knows, and every Freemason who has taken the Third Degree ought to know, what was the peculiar construction, character, and use of the Sanctum Santorum of Holy of Holies in King Solomon's Temple. Situated in the western end of the Temple, separated from the rest of the building by a heavy curtain, and enclosed on three sides by dead walls without any aperture or window, it contained the Sacred Ark of the Covenant, and was secluded and set apart from all intrusion save of the High Priest, who only entered it on on certain solemn occasions. As it was the most sacred of the three parts of the Temple, so has it been made symbolic of a Master's Lodge, in which are performed the most sacred rites of initiation in Ancient Craft Freemasonry.
