[WORLDMAP]

This work was based off Kircher's visit to Sicily in 1637-8 when Etna and Stromboli both erupted. This observation led him to conclude that the earth's center as a massive internal fire and that volcanoes acted as safety valves. His work speculated on geology, hidden lakes, rivers of fire, strange inhabitants, the sun, the moon, eclipses, currents, meteorology, medicines, poisons, and even fireworks. The work must always command a high place in the literature as the first effort to describe the earth from a physical standpoint. (Zittel, p. 25)
