# The Dendera Tubes. More specifically, these are images on an Egyptian bas-relief of tube-like structures in the hands of Egyptian priests or acolytes. At least one electrical engineer has stated that the objects depicted in that bas-relief are Crookes tubes, which were the forerunners of the cathode-ray tubes still in common use in [[television]] receivers.<ref name=top10/>

# The Ashoka Pillar in Delhi, India. This wrought-iron shaft supposedly dates to an Indian king who died in 413 AD. The metal, which ought to have crumbled into rust long ago, remains in excellent condition.<ref name=top10/>

# The Antikythera Computer, a geared structure recovered in 1900 from the wreck of a merchant vessel that, to judge from the other cargo it carried, apparently sank sometime between 85 BC and 50 BC. This object was a highly sophisticated and easy-to-use [[orrery]] that predicted the annual motions of the [[sun]] and [[moon]] in the earth's sky.<ref name=top10/><ref name=AncientX/>

# An Inca pendant, dated from 500 to 800 AD, that turns out to be a model of a high-speed aircraft, possibly a jet. More remarkably, the object's apparent rudder fin bears an engraved [[Hebrew]] or [[Aramaic]] letter beth.<ref name=top10/><ref name=s8int/>
