There have been, and will be again, many destructions

"There have been, and will be again, many destructions of mankind arising out of many causes; the greatest have been brought about by the agencies of fire and water, and other lesser ones by innumerable other causes.

There is a story, which even you have preserved, that once upon a time Phaëton, the son of Helios, having yoked the steeds in his father's chariot, because he was not able to drive them in the path of his father, burnt up all that was upon the Earth and was himself destroyed by a thunderbolt.

Now this has the form of a myth, but really signifies a declination of the bodies moving in the heavens around Earth and a great conflagration of things upon Earth, which recurs after long intervals…
