Forty-seventh Problem of Euclid.
This was an invention of our ancient friend and brother Pythagoras, who, in his travels through Asia, Africa and Europe, was initiated into several orders of priesthood, and raised to the sublime degree of Master Mason. This wise philosopher enriched his mind abundantly in a general knowledge of things and more especially in Geometry, or Masonry. On this subject he drew out many problems and theorems; and among the most distinguished he erected this, which, in the joy of his heart, he called Eureka, in the Grecian language signifying "I have found it;" and upon the erection of which he is said to have sacrificed a hecatomb. It teaches Masons to be general lovers of the arts and sciences.
