Athanasii Kircheri ... Mundus subterraneus in XII libros digestus
Athanasius Kircher's Mundus subterraneus, published in Amsterdam in 1678 by Janssonius van Waesberge and sons, is a Latin natural-philosophy treatise on the earth's interior, volcanoes and underground waters, written for scholars and collectors. Its engravings are schematic diagrams: geometric solids, idealized island maps with rivers and volcanic craters, and emblematic symbols such as crosses and stars, showing how the seventeenth century pictured hidden natural forces.
