“One of the great joys of Paris is its wealth of niche museums, and there’s nowhere greater—or more atmospheric—in that regard than the Musée de la Chasse et de la Nature, the museum of hunting and nature.... The deliciously macabre displays of taxidermy are a highlight, but the museum also manages to avoid feeling too fusty by bringing in contemporary artists to produce works in conversation with its collections, from Sterling Ruby to Jeff Koons.” — Liam Hess, Vogue, 27 Sept. 2023

Did you know?

A long and winish road led fusty to English’s door. While that road is a bit obscured, evidence suggests that fusty comes from the Middle English noun foist, meaning “wine cask,” which in turn traces back to the Medieval Latin word fustis, meaning “tree trunk” or “wood.” Fusty itself originally described wine that had gone stale from sitting in the cask too long; fusty literally meant that the wine had the “taste of the cask.” Eventually, fusty was used across the culinary universe for any stale food, and especially for damp or moldy food. Those damp and moldy connotations later led fusty to be applied to musty places, and later still to anything that had lost its freshness and interest—that is, to anything old-fashioned.
