Greek fire....in the sky bump.
Proving, once again, that astrophysics is all Greek to me.
After 500 years, they figured out how to melt/hammer it down and make fine edged weapons?
According to ancient authors, from Aristotle onwards, a meteorite the size of a “wagonload” crashed into northern Greece sometime between 466 and 468 BC. They beat their wagonload of plowshares into swords and spears.
The ancient Greeks then went on to speculate that the proliferation of large wagons on the streets of Greece were the cause of this incident, and were contributing to global warming. Unless such wagons were outlawed, it was feared that life as they knew it would vanish by 325 B.C.

It’s unlikely that rocks coming down from Halley’s Comet would be made of pure iron.
