Today, we take for granted nightly city skylines, streetlights, and the overall power that drives our modern convenience. But, could the wise-men of ancient Egypt and Mesopotamia have had knowledge of electricity, even electric illumination, or even electric-based technology? Within the framework of some archaeological evidence, the answer seems affirmative.
The most widely cited evidence that the ancient Egyptians used electricity is a relief beneath the Temple of Hathor at Dendera, Egypt that depicts figures standing around a large light-bulb-like object.
An Ancient Light Bulb?
