“In the Egyptian section of the Dresden, or Berlin Museum, we forget which, is a drawing which represents a workman ascending an unfinished pyramid, with a basket of sand upon his back. This has suggested to certain Egyptologists the idea that the blocks of the pyramids were chemically manufactured in loco. Some modern engineers believe that Portland cement, a double silicate of lime and alumina, is the imperishable cement of the ancients.
But, on the other hand, Professor Carpenter asserts, that the pyramids, with the exception of their granite casing, is formed of what “geologists call nummulitic limestone. This is newer than the old chalk, and is made of the shells of animals called nummulites, like little pieces of money about the size of a shilling.” However this moot question may be decided, no one, from Herodotus and Pliny, down to the last wandering engineer who has gazed upon these imperial monuments of long-crumbled dynasties, has been able to tell us how the gigantic masses were transported and set up in place.
Brunsen concedes to Egypt an antiquity of 20,000 years. But even in this matter we would be left to conjecture if we depended upon modern authorities. They can neither tell us for what the pyramids were constructed, under what dynasty the first was raised, nor the material of which they are built. All is conjecture with them.
Professor Smyth has given us by far the most accurate mathematical description of the great pyramid to be found in literature. But after showing the astronomical bearings of the structure, he so little appreciates ancient Egyptian thought, that he actually maintains that the porphyry sarcophagus of the king’s chamber is the unit of measure for the two most enlightened nations of the earth, England and America.”
One of the books of Hermes describes certain of the pyramids as standing upon the seashore, “the waves of which dashed in powerless fury against its base.” This implies that the geographical features of the country have been changed, and may indicate that we must accord to these ancient “granaries”, “magico-astrological observatories”, and “royal sepulchres”, an origin antedating the upheaval of the Sahara and other deserts. This would imply rather more of an antiquity than the poor few thousands of years, so generously accorded to them by Egyptologists.”
