The Egyptians used electricity ...which also answers how detailed and beautiful hieroglyphs and paintings could be done inside pyramids where there was no light. Archaeologists used to speculate that torches or fires were used, but no soot, smoke or burn marks have ever been found in any of the pyramid ceilings or walls. So how can a modern lens be made in 4000 BC Egypt?

The fact is that I have located more than 450 ancient lenses in museums all round the world, and I even own a Greek crystal lens of the 6th century BC myself.

The earliest actual lenses which I have located are crystal ones dating from the 4th Dynasty of Old Kingdom Egypt, circa 2500 BC. These are to be found in the Cairo Museum and two are in the Louvre in Paris. But archaeological evidence showing that they must have been around at least 700 years earlier has recently been excavated at Abydos in Upper Egypt. A tomb of a Pre-Dynastic king there has yielded an ivory knife handle bearing a microscopic carving which could only have been done under considerable magnification (and of course can only be seen with a strong magnifying glass today). Thus, we know that magnification technology was in use in Egypt in 3300 BC.

But magnification technology was not of interest merely for making and viewing small carvings. Its most important use was in telescopes.

If there is all this evidence, why has no one ever talked about it before?…...
