Antique geology and hydrology imagined beneath the earths crust in the 1600s!

Behold the geological splendor of this art print set of Athanasius Kircher's "Subterranean Fires" & "Subterranean Waters" from the year 1668!

Witnessing the 1638 eruptions of Aetna and Stromboli, Kircher became increasingly fascinated with geological and meteorological phenomena. Upon his return to Naples, he had himself lowered into the active crater of Vesuvius to make firsthand observations. From his investigations and research, Kircher concluded that continually circulating channels of fire (for which volcanoes act as occasional safety valves) and water honeycombed the Earth's interior, and that these forces, in conjunction with the wind, were responsible for all weather and geological events.

These ideas formed the thesis of Kircher's most renowned book, Mundus Subterraneus (Subterranean World). While primarily a geological textbook, this massive and copiously illustrated volume contained discussions of gravity, the moon, the sun, eclipses, ocean currents, hydraulics, saline analyses, fossils & petrifaction, remains of giants, subterranean beasts and demons, poisons, metallurgy, the Universal Seed, the generation of insects, astrological medicine and fireworks.
