The meaning of words can vary from context, and this article about an “Ancient U.S. Weapon” in Syria brought home this point to me.
If you consider that ancient often means “the earliest recorded memory” or sometimes “before our civilization as we know it began”, then definitions can vary across disciplines. In historical linguistics, “ancient” is usually no later than the Roman Empire (at least in my estimation), yet the Academy of Ancient Music is playing pieces by Handel from 1685, which is about the time period when known compositions can be firmly reconstructed. Another semi-amusing case is the PBS program In Search of Ancient Ireland – which apparently ends with the Norman invasion in the 1100s (well into the Middle Ages again). I suspect that any era when Wales, Ireland or Scotland was still under the control of a Celtic language government will be “ancient”.
Still the words “Ancient U.S.” really gave me pause. I know that pre-European history is “Ancient”, although it generally ends between 1492 to 1900 depending on location. But the U.S. itself as “ancient”? That is a new concept for me. Especially since the artifacts were weapons from the 1970s used in the Vietnam War. I actually remember when the troops left Saigon, so definitely in my lifetime.
