Natural Questions, Volume I

Seneca (c. 4-65 CE) devotes most of Naturales Quaestiones to celestial phenomena. In Book 1 he discusses fires in the atmosphere; in 2, lightning and thunder; in 3, bodies of water. Seneca’s method is to survey the theories of major authorities on the subject at hand, so his work is a guide to Greek and Roman thinking about the heavens.
