There are no traces of smoke or ash on the ceilings of these temples, so how did they see inside the dark recesses, copper reflectors can only bounce light so far down the shafts. Watch the video below for an in-depth analysis.

    • The small earthenware jar has an asphalt seal on the lid, and has an iron rod with a copper cylinder around it. Reproductions of the jar, when filled with any acid such as vinegar, produce about 2 volts of electricity. The jar is thought to have been used to electroplate small items. By electroplating, silver or other jewelry could be plated with gold, or copper plated with silver. One source states that local craftsmen in Iraq still use a primitive method of electroplating to plate jewelry.
