But increasingly, technology is making it possible, and historians, scientists, and perfumers are now taking the idea of smells as historical artifacts more seriously. They argue that it’s time to delve into our olfactory past, trying harder to understand how people experienced the world with their noses - and even save scents for posterity. Their efforts have already made it possible to smell fragrances worn a century ago, to re-create the smell of a rare flower even if it goes extinct, and to better understand the smells that ancient cultures appreciated or detested.
