Über die Vulkane im Monde

A meticulous exploration of an eighteenth‑century scientific controversy, this work follows a lively exchange of letters among European scholars debating whether the Moon’s dark, ring‑shaped spots are the remnants of ancient volcanoes. Drawing on reports from the Russian court, observations by Herschel, and the earlier conjectures of figures like Beccaria and Lichtenberg, the author reconstructs the arguments that linked lunar features to familiar Earthly geology.

The narrative weaves together detailed comparisons of lunar craters with terrestrial formations—from the modest volcanic domes barely visible from afar to the massive basins that shape entire continents. By juxtaposing the limited telescopic evidence with contemporary geological theory, the text illustrates how early astronomers grappled with the limits of observation and the allure of analogies across worlds. Listeners will gain insight into the intellectual atmosphere of the Enlightenment, when the heavens were still being mapped with the tools of philosophy, correspondence, and curiosity.
