'The Mysterious Comet' examines the relationship between the Earth and other bodies in space, with or without 'fixed' orbits, noting the effects on various systems, weather and otherwise. He notes the interaction between comets, meteors, meteorites and volcanoes, and the manner in which all life is sustained by the replenishment of air and water and other energies brought by cometary bodies.
Comyns Beaumont brings together accounts of the earthquakes and eruptions of his day and those from history along with meteorological and astronomical accounts and mythical references. He builds on neo-platonic and catastrophist theories and places Atlantis in the region of the British Isles.
A fascinating and thorough book with lots of well indexed references for readers interested in doing further research.
