Gibbon's Decline and Fall is always a wonderful read.
In the second year of the reign of Valentinian and Valens, on the morning of the twenty first day of July, the greatest part of the Roman world was shaken by a violent and destructive earthquake ... This calamity, the report of which was magnified from one province to another, astonished and terrified the subjects of Rome; and their affrighted imagination enlarged the real extent of a momentary evil. They recollected the preceding earthquakes, which had subverted the cities of Palestine and Bithynia: they considered these alarming strokes as the prelude only of still more dreadful calamities, and their fearful vanity was disposed to confound the symptoms of a declining empire, and a sinking world. It was the fashion of the times, to attribute every remarkable event to the particular will of the Deity; the alterations of nature were connected, by an invisible chain, with the moral and metaphysical opinions of the human mind; and the most sagacious divines could distinguish, according to the colour of their respective prejudices, that the establishment of heresy tended to produce an earthquake; or that a deluge was the inevitable consequence of the progress of sin and error. Without presuming to discuss the truth or propriety of these lofty speculations, the historian may content himself with an observation, which seems to be justified by experience, that man has much more to fear from the passions of his fellow-creatures, than from the convulsions of the elements.
