Note 178 — Chapter XV
Reading edition
This was the "Great Comet of 1680." Dr. B. A. Gould writes me: "It appeared in December, 1680, and was visible until the latter part of February, 1681, being especially brilliant in January." It was said to be the largest ever seen. By observations upon it, Newton demonstrated the regular revolutions of comets around the sun. "No comet," it is said, "has threatened the earth with a nearer approach than that of 1680." (Winthrop on Comets, Lecture II. p. 44.) Increase Mather, in his Discourse concerning Comets, printed at Boston in 1683, says of this one: "Its appearance was very terrible; the Blaze ascended above 60 Degrees almost to its Zenith." Mather thought it fraught with terrific portent to the nations of the earth.
