This paper seeks to locate Seneca's treatment of earthquakes in Natural Questions 6 in the broader ancient seismological tradition; and, more particularly, to examine the initiatives which potentially transform his treatment into a highly original mode of literary-philosophical investigation not just into the cause of earthquakes, but also of how a ‘scientific’ understanding of them can at least partially quell the intimidating effect of such wonders of nature. On this approach Natural Questions 6 is perhaps concerned not so much with earthquakes per se but with shaping attitudes towards the natural world as a whole, inculcating in us a vision of such phenomena as but ‘normal’ aspects of cosmic functioning. By this method the book promotes within us a different, engagingly Senecan appreciation of cosmic integrity.
