Many ancient stories credit volcanic eruptions to supernatural causes, such as the actions of gods or demigods. To the ancient Greeks, volcanoes' impulsive power could only be made clear as proceedings of the gods, while 16th-17th century German astronomer Johannes Kepler considered that they were tubes for the Earth's tears. One early idea to this was proposed by Jesuit Athanasius Kircher , who witnessed eruptions of Mount Etna and Stromboli, then visited the crater of Vesuvius and issued his view of a world with a central fire connected to many others caused by the burning of sulfur, bitumen and coal.
Different explanations were suggested for volcano behavior before the recent understanding of the Earth's mantle arrangement as a half solid material was developed. For decades after understanding that density and radioactive materials may be heat sources, their donations were explicitly reduced. Volcanic action was frequently credited to chemical responses and a thin layer of molten rock close to the exterior.
