At Stonehenge on site, Stone #40g is located nearby to and to the upper right of Stonehenge Stone #19, which we have previously identified as Sagittarius. That location meshes with the Center of the Galaxy identification.
Presumably, the cover was made of the heavy metal lead to show the "weight" of the presumed center of gravity in our universe while the "weighty" stone was symbolically buried underground underneath it.
The shape of the lead cover, if we have drawn it correctly, in spite of not being able to see it in entirety, is the shape of a human head facing right. It is identical in concept to the "head shape" of Stonehenge that we previously have identified as being the original shape of Stonehenge and not a perfect circle, as has otherwise long been thought to be the case by mainstream scholarship.
The ancients shaped their world view according to themselves and their own physical world, not according to precepts of geometry. That is a modern foible.
We subsequently show our decipherment of Stonehenge Stone #40g in a series of individual postings which show -- progressively -- how we "deciphered" such a stone by identifying the stone markings and equating them with comparable stars in a sky map clipped via Starry Night Pro 3.1 astronomy software. Of course, you have to know where to LOOK, which is the essence of science, LOOKING and OBSERVING, something the mainstream has done too little.
We start the graphic presentation in the next posting as:
1st - Stonehenge Stone #40g Lead Cover Decipherment as the Galactic Center
and will then proceed in the posting after that to
2nd - Stonehenge Stone #40g Lead Cover Decipherment as the Galactic Center
etc.
You may have to flip back and forth between postings to see what is happening or print out the image in this posting and then compare it to the decipherment.
