“All these had knowledge from above, that the Almighty would take vengeance for sin either by fire or by water, so great was the wickedness of the world. So they reasoned among themselves how they might preserve the knowledge of the sciences which they had found, and Jabal said that there were two different kinds of stone of such virtue that one would not burn and the other would not sink–the one called marble and the other latres. They then agreed to write all the science that they had found upon these stones."
After the destruction of the world, these two pillars were discovered by Hermes, a son of Shem. Then the craft of masonry began to flourish, and Nimrod was one of the earliest patrons of the art. So, we learn that, from the Bible, through Cain’s ancestry was revealed knowledge of the sciences and arts through the Watchers – “worthless knowledge” that God refers to when rebuking the fallen angels as written in the Book of Enoch.
“And now as to the Watchers who have sent thee to intercede for them, who had been aforetime in heaven, (say to them): “You have been in heaven, but all the mysteries had not yet been revealed to you, and you knew worthless ones, and these in the hardness of your hearts you have made known to the women, and through these mysteries women and men work much evil on earth.” And that, to preserve this “knowledge” they etched it on two pillars (or monoliths), which after the flood, were discovered by Hermes, and then Freemasonry began, whereupon Nimrod was the first patron.
