This last comet was visible in the month of December, 1680. Bayle, who began his Pensees sur la Comete in January, 1681, (Oeuvres, tom. iii.,) was forced to argue that a supernatural comet would have confirmed the ancients in their idolatry. Bernoulli (see his Eloge, in Fontenelle, tom. v. p. 99) was forced to allow that the tail though not the head, was a sign of the wrath of God.
