"On the other side, Incensed with indignation, Satan stood. Unterrified, and like a comet burned, That fires the length of Ophiuchus huge In the arctic sky, and from its horrid hair Shakes pestilence and war." We do indeed find that in some minds the discoveries of Tycho Brahe and Kepler begin to take effect, for, in 1621, Burton in his Anatomy of Melancholy alludes to them as changing public opinion somewhat regarding comets; and, just before the middle of the century, Sir Thomas Browne expresses a doubt whether comets produce such terrible effects, "since it is found that many of them are above the moon."(100) Yet even as late as the last years of the seventeenth century we have English authors of much power battling for this supposed scriptural view and among the natural and typical results we find, in 1682, Ralph Thoresby, a Fellow of the Royal Society, terrified at the comet of that year, and writing in his diary the following passage: "Lord, fit us for whatever changes it may portend; for, though I am not ignorant that such meteors proceed from natural causes, yet are they frequently also the presages of imminent calamities." Interesting is it to note here that this was Halley's comet, and that Halley was at this very moment making those scientific studies upon it which were to free the civilized world forever from such terrors as distressed Thoresby.

For Burton, see his Anatomy of Melancholy, part ii, sect 2. For Browne, see the Vulgar and Common Errors, book vi, chap. xiv. The belief in comets as warnings against sin was especially one of those held "always, everywhere, and by all," and by Eastern Christians as well as by Western. One of the most striking scenes in the history of the Eastern Church is that which took place at the condemnation of Nikon, the great Patriarch of Moscow. Turning toward his judges, he pointed to a comet then blazing in the sky, and said, "God's besom shall sweep you all away!" Of all countries in western Europe, it was in Germany and German Switzerland that this superstition took strongest hold. That same depth of religious feeling which produced in those countries the most terrible growth of witchcraft persecution, brought superstition to its highest development regarding comets. No country suffered more from it in the Middle Ages. At the Reformation Luther declared strongly in favour of it. In one of his Advent sermons he said, "The heathen write that the comet may arise from natural causes, but God creates not one that does not foretoken a sure calamity." Again he said, "Whatever moves in the heaven in an unusual way is certainly a sign of God's wrath." And sometimes, yielding to another phase of his belief, he declared them works of the devil, and declaimed against them as "harlot stars."(101)
