ther without influence. The convenient fiction, indeed, that some
comets operate quickly and others slowly, made it very difficult for a
comet to appear to which some evil effects could not be ascribed. If any
one can find a single date, since the records of history have been
carefully kept, which was so fortunately placed that, during no time
following it within five years, no prince, king, emperor, or pope died,
no war was begun, or ended disastrously for one side or the other
engaged in it, no revolution was effected, neither plague nor pestilence
occurred, neither droughts nor floods afflicted any nation, no great
hurricanes, earthquakes, volcanic outbursts, or other trouble was
recorded, he will then have shown the bare possibility that a comet
might have appeared which seemed to presage neither abrupt nor
slow-moving calamities. But it is not possible to name such a date, nor
even a date which was not followed within two years at the utmost by a
calamity such as superstition might assign to a comet. And so closely
have such calamities usually followed, that scarce a comet could appear
which might not be regarded as the precursor of very quickly approaching
calamity. Even if a comet had come which seemed to bring no trouble,
nay, if many such comets had come, men would still have overlooked the
absence of any apparent fulfilment of the predicted troubles. Henry IV.
well remarked, when he was told that astrologers predicted his death
because a certain comet had been observed: 'One of these days they will
predict it truly, and people will remember better the single occasion
when the prediction will be fulfilled than the many other occasions when
it has been falsified by the event.'

The troubles connected with the comets of 1680 and 1682 were removed
farther from the dates of the events themselves than usual, at least so
far as the English interpretation of the comets was concerned. 'The
great comet in 1680,' says one, 'followed by a lesser comet in 1682, was
evidently the forerunner of all those remarkable and disastrous events
that ended in the revolution of 1688. It also evidently presaged the
revocation of the edict of Nantes, and the cruel persecution of the
Protestants, by the French king Louis XIV., afterwards followed by those
terrible wars which, with little intermission, continued to ravage the
finest parts of Europe for nearly twenty-four years.'

If in some respects the fears inspired by comets have been
