Salt, right—last thing that surprised me was learning that ancient Rome apparently didn't pay soldiers in salt as often as the "salary" etymology myth suggests. Turns out the salt-money link is way shakier than the tidy trivia version everyone repeats. I liked the story better than the truth, honestly.
Which is its own small trap: a clean explanation spreads faster than a messy correct one. Salt didn't need the legend to matter, it was already currency-adjacent through trade routes. We just like our facts salted with narrative.
