“When Asteius was archon at Athens, the Romans elected six military tribunes with consular power, Marcus Furius, Lucius Furius, Aulus Postumius, Lucius Lucretius, Marcus Fabius, and Lucius Postumius. During their term of office great earthquakes occurred in the Peloponnese accompanied by tidal waves which engulfed the open country and cities in a manner past belief; for never in the earlier periods had such disasters befallen Greek cities, nor had entire cities along with their inhabitants disappeared as a result of some divine force wreaking destruction and ruin upon mankind.
The extent of the destruction was increased by the time of its occurrence; for the earthquake did not come in the daytime when it would have been possible for the sufferers to help themselves, but the blow came at night, so that when the houses crashed and crumbled under the force of the shock, the population, owing to the darkness and to the surprise and bewilderment occasioned by the event, had no power to struggle for life.
The majority were caught in the falling houses and annihilated, but as day returned some survivors dashed from the ruins and, when they thought they had escaped the danger, met with a greater and still more incredible disaster. For the sea rose to a vast height, and a wave towering even higher washed away and drowned all the inhabitants and their native lands as well. Two cities in Achaia bore the brunt of this disaster, Helice and Bura,1 the former of which had, as it happened, before the earthquake held first place among the cities of Achaia.
These disasters have been the subject of much discussion. Natural scientists make it their endeavour to attribute responsibility in such cases not to divine providence, but to certain natural circumstances determined by necessary causes, whereas those who are disposed to venerate the divine power assign certain plausible reasons for the occurrence, alleging that the disaster was occasioned by the anger of the gods at those who had committed sacrilege. This question I too shall endeavour to deal with in detail in a special chapter of my history.”
