King Arthur, The Sorcerer's Stone, and the Holy Grail
The Sumerians had the recipe for a substance that under the right conditions had negative weight, gave of light and many other extreme properties. This was the food of the gods, the original ambrosia. Part of the recipe included the menstral blood of women, the original "Sangreal" or HOLY GRAIL This stuff was able to change metal properties... alchemy. It also had many other "magical" properties. It is thought that Freemasons (uh, stoneworkers)have protected the knowledge of the stone, along with other esoteric knowledge of construction. This knowledge is probably how larg stones were moved to build the Egyptian pyramids.
The knowledge passed along with those that knew how to build, were able to build teh tower of babel and the pyramids. This knowledge was passed to Noah in order to build his Ark without mishap. The Hebrews, decendents of Noah were able to use this knowlegde when they slaved over the pyramids. This knowlede helped build the Temple of Solomon and allowed its construction to stand. The bible traces extraordinary feats of engineering that were well ahead of their time. Noah built a boat. Solomon built a temple. Babylonians built a tower. Hebrew slaves built the pyramids. Jesus himself was a carpenter. The royal bloodline is a family of mastercraftsmen.
The keystone was a protected secret of the Freemasons.
One of our cultural legends describes a young man who removes a sword of tremendous and possible magical properties from a stone. We have all seen the Disney rendition of Wort removing the sword from the stone. Even more interesting is that this man who removed Excalibur was considered of the line of priestesses from Avalon, and grew to become the King presiding of the Knights of the Round Table, a legend based on Templar knights of the Crusades. Crusades determined to find the Holy Grail. What if the stone GAVE the sword its properties? (what if the "sorcerer's stone" creatd Arthur's sword and gave it its near magcal properties?) The story makes more sense if a young apprentice masters a significant scientific art (to the extent that most adults could not 'extract' the sword from the stone) at a precocious age.
The soceror's stone is said to be of the substance of the sumerian god's ambrosia. It was for this "stone" that Nicolas Flammel's home was repeated torn apart after his death. Nicolas Flammel s listed as a Grand Master of the Priory de Sion, along with Newton, Boyle, and DaVinci- all such masters of their craft that we still teach their theories hundreds of years after their deaths.
Nuclear physics has discovered that if you reverse the spin of electrons in certain metals, then many often properties described by the sumerians in their writings.
Yes, there is a secret that the masons/templars protect. The Holy Grail is from the womb of a woman- but it is the blood itself that is considered sacred...not the offspring of the womb.
