A comparative study of similar classic adventures…has convinced even the most cautious and conservative gold chroniclers that Ponce de Leon's exploit, far from being a wild-goose chase, was in fact a most sanguine telluric adventure undertaken to reestablish the hegemony of the rapidly disappearing yellow metal. -- Henry Miller, "Money and How It Gets That Way," Stand Still Like the Hummingbird, 1962
Telluric is derived from the Latin word tellūs meaning "earth." It entered English in the early 1800s.
