 Fall of Atlantis

"But the divine revenge overtook not long after those proud enterprises. For within less than the space of one hundred years, the great Atlantis was utterly lost and destroyed: not by a great earthquake, as your man saith; (for that whole tract is little subject to earthquakes;) but by a particular' deluge or inundation; those countries having, at this day, far greater rivers and far higher mountains to pour down waters, than any part of the old world.
