Ancient Egyptian Electricity
It is a popular belief in alternative science that our ancestors had a much greater technological knowledge than our schoolbook science (1) is willing to accept. Many of those theories are lacking serious foundation and are often based on some crazy ideas. But the theory that electricity was known and used in ancient times seems to rest on (2) a much more serious basis.
The key to the whole theory lies a few hundred kilometers east of Egypt, in today’s Iraq. There some strange pots were found. Some contained copper cylinders, glued into the opening with asphalt. In the middle of the cylinder was an iron rod, held in place also with asphalt. The archaeologist who found the first of these pots in 1936 was sure that this was a galvanic element, a primitive battery. Reconstructions did indeed show that it was possible to create electricity with it.
Another key element for this theory is actually something that is missing. It’s a riddle where schoolbook science is capitulating (3 . This element is soot, a dirty black powder that is produced when you burn something such as coal or wood. In none of the many thousands of underground tombs and pyramid rooms was a single trace of soot found, although many of these tombs are full of often colourful paintings. But the primitive light sources the Egyptians knew such as candles and oil lamps.?
are always leaving soot and arc using oxygen. So how did the Egyptians get their light?
In the temple in Dendera, several dozens of kilometers north of Luxor, some experts found the light (4 . A Norwegian electrical engineer noticed that the object drawn on the top of the wall could work as a lamp. An Austrian colleague was able to construct a working model, and two well known authors Peter Krassa and Rainer Habeck, could even work out a real theory based on it.
What we see is without question a form of bulb, with two arms reaching into it near its thick end, and a sort of cable at the other end, from where a snake is leaping out to touch the arms on the other side. The whole device really looks like a lamp.
Is this the proof? Did the Egyptians know and use electric lights? If so, where did they get the principle from? Was it from their own invention, or did they have help?
