Note 273 — IS THE GREAT PYRAMID OF GIZEH A METROLOGICAL MONUMENT?

"The clue was not prepared for any immediate successors of the builders, but was intended, on the contrary, to endure to a most remote period. And it has so endured and served such a purpose even down to those our own days." (Professor Smyth's Life and Work at the Great Pyramid, vol. i. p. 157.) "The builders, or planners rather, of the Great Pyramid, did not leave their building without sure testimony to its chief secret; for there, before the eyes of all men for ages, had existed these two diagonal joints in the passage floor, pointing directly and constantly to what was concealed in the roof just opposite them, and no one ever thought of it. Practically, then, we may say with full certainty that these two floor marks were left there to guide men who, it was expected, would come subsequently, earnestly desiring, on rightly-informed principles, to look for the entrance to the upper parts of the Pyramid." (Vol. i. p. 156-7.) At p. 270 Professor Smyth again alludes to this supposed mark, made up by two diagonal joints in the passage floor, as evading the notice of all visitors, except "those very few, or perhaps even that one only man, who had been previously instructed to look for a certain almost microscopic mark on the floor."
