It is a widespread belief in alternative science that our forefathers possessed a much greater technological knowledge than our schoolbook science is willing to accept. Many of those theories are lacking serious foundation and are often based on overdrawn speculations. But the theory that electricity was known and used in antiquity seems to rest on a much more stable foundation. In this temple in Dendera, several dozens of kilometers north of Luxor, some experts found the light. A Norwegian electrical engineer noticed that the object shown on the relief on top of this page coud work as a lamp. An Austrian colleague was able to construct a working model, and two well known authors in the AAS, 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 ensemble really looks like a lamp.
