Now, from apex to base, the volume of the Great Pyramid in cubic inches is approximately 161,000,000,000. How many human souls, then, have lived on the earth from Adam to the present day? Somewhere between 153,000,000,000 and 171,900,000,000.
—Piazzi Smyth, Our Inheritance in the Great Pyramid, London, Isbister, 1880, p. 583
“I imagine your author holds that the height of the pyramid of Cheops is equal to the square root of the sum of the areas of all its sides. The measurements must be made in feet, the foot being closer to the Egyptian and Hebrew cubit, and not in meters, for the meter is an abstract length invented in modern times. The Egyptian cubit comes to 1.728 feet. If we do not know the precise height, we can use the pyramidion, which was the small pyramid set atop the Great Pyramid, to form its tip. It was of gold or some other metal that shone in the sun. Take the height of the pyramidion, multiply it by the height of the whole pyramid, multiply the total by ten to the fifth, and we obtain the circumference of the earth. What’s more, if you multiply the perimeter of the base by twenty-four to the third divided by two, you get the earth’s radius. Further, the area of the base of the pyramid multiplied by ninety-six times ten to the eighth gives us one hundred and ninety-six million eight hundred and ten thousand square miles, which is the surface area of the earth. Am I right?”
Belbo liked to convey amazement with an expression he had learned in the cinematheque, from the original-language version of Yankee Doodle Dandy, starring James Cagney: “I’m flabbergasted!” This is what he said now. Aglie also knew colloquial English, apparently, because he couldn’t hide his satisfaction at this tribute ttrhis vanity. “My friends,” he said, “when a gentleman, whose name is unknown to me, pens a compilation on the mystery of the pyramids, he can say only what by now even children know. I would have been surprised if he had said anything new.”
“So the writer is simply repeating established truths?” “Truths?” Aglie laughed, and again opened for us the box of his deformed and delicious cigars. “Quid est veritas, as a friend of mine said many years ago. Most of it is nonsense. To begin with, if you divide the base of the pyramid by exactly twice the height, and do not round off, you don’t get IT, you get 3.1417254. A small difference, but essential. Further, a disciple of Piazzi Smyth, Flinders Petrie, who also measured Stonehenge, reports that one day he caught the master chipping at a granite wall of the royal antechamber, to make his sums work out...Gossip, perhaps, but Piazzi Smyth was not a man to inspire trust; you had only to see the way he tied his cravat. Still, amid all the nonsense there are some unimpeachable truths. Gentlemen, would you follow me to the window?”
He threw open the shutters dramatically and pointed. At the corner of the narrow street and the broad avenue, stood a little wooden kiosk, where, presumably, lottery tickets were sold.
“Gentlemen,” he said, “I invite you to go and measure that kiosk. You will see that the length of the counter is one hundred and forty-nine centimeters—in other words, one hundred-billionth of the distance between the earth and the sun. The height at the rear, one hundred and seventy-six centimeters, divided by the width of the window, fifty-six centimeters, is 3.14. The height at the front is nineteen decimeters, equal, in other words, to the number of years of the Greek lunar cycle. The sum of the heights of the two front corners and the two rear corners is one hundred and ninety times two plus one hundred and seventy-six times two, which equals seven hundred and thirty-two, the date of the victory at Poitiers. The thickness of the counter is 3.10 centimeters, and the width of the cornice of the window is 8.8 centimeters. Replacing the numbers before the decimals by the corresponding letters of the alphabet, we obtain C for ten and H for eight, or C10H8, which is the formula
