Etymology: "Mercurialists" is the plural of "mercurialist," a word formed from "mercurial" plus the suffix "-ist," meaning a person who follows or embodies a particular quality. The real story lies in the adjective it comes from. "Mercurial" traces back to Mercury, the Roman messenger god, whose swiftness and restlessness gave the word its first sense of quick, lively movement. Over time it came to describe unpredictable, volatile changes of mood and temperament, so a mercurialist is someone who champions or embodies that fluidity. The base word's connection to the metal mercury, a liquid that moves and shifts easily, reinforces the sense of quicksilver instability. Because "mercurial" is itself a derivative of the god's name, the whole family of words points back to a single mythological figure whose name suggests speed and changeability.
