“No subsequent people has been so proficient in geometry as the builders of the Pyramids and the other Titanic monuments, antediluvian and postdiluvian. On the other hand, none has ever equaled them in practical interrogation of nature.
An undeniable proof of this is the significance of their countless symbols. Every one of these symbols is an embodied idea – combining the conception of the Divine Invisible with the earthly and visible.
The former is derived from the latter strictly through analogy according to the hermetic formula – “as below, so it is above.” Their symbols show great knowledge of natural sciences and a practical study of cosmical power.
As to practical results to be obtained by “the investigations of geometry”, very fortunately for students who are coming upon the stage of action, we are no longer forced to content ourselves with mere conjectures.
In our own times, an American, Mr. George H. Felt, of New York, who, if he continues as he has begun, may one day be recognized as the greatest geometer of the age, has been enabled, by the sole help of the premises established by the ancient Egyptians, to arrive at results which we will give in his own language.”
