No, it’s not a region in France. Provenance is a thing’s origin or source, and the history of its subsequent owners. It’s important when, for example, selling works of fine art. If you find a long lost Picasso in your granny’s attic you might have trouble convincing the experts it’s real, even if it looks real. If it’s very good, you might be able to sell it for a decent amount of cash, but doubt about its origin will mean you only get a fraction of what a verified Picasso would fetch. But if your granny could prove she worked as, say, Picasso’s housekeeper during the period he produced that type of work, you might get a lot more. The quality of its provenance would make it more likely the work was genuine. Provenance is a necessary factor in the valuation of art – to determine that it is (a) genuine and (b) legally owned.

Provenance is also useful in determining the validity of scientific claims. If the claim is based on earlier sound science – backed by quality evidence – it is more likely to be true. Not certain to be true, of course. But it will at least have scientific plausibility. But if the claim is based on something that was just made up, then it seems much less likely it would be true.
