The Dendera light is a particularly controversial topic since it is not exactly an artefact of potential ancient technology, but the possible depiction of an artefact on a wall of one of the best preserved ancient temples in Egypt—the temple of the Egyptian goddess Hathor at Dendera. The Dendera light is found on three stone reliefs and, at first glance, could be construed as a lamp with a cable at the end and a snake-shaped cord inside. A priest is holding the lamp at one end, and a few smaller figures are below it with one appearing to hold the lamp upwards.
