When the heavens blazed: a rare tract on the 1811 comet

The Great Comet of 1811 shone for nine months, making it one of the most remarkable astronomical events in history, unmatched until Hale–Bopp in 1997.

Astronomers tracked it for a record-breaking 511 days, while across Europe and America, it captured the imagination of emperors, vintners, and ordinary citizens alike. Napoleon took it as a divine omen for his Russian campaign; winemakers hailed the year as one of the finest for vintages.

This scarce religious tract, printed in Boston by Lincoln and Edmands, captures how ordinary believers interpreted the comet’s appearance. Written as a dialogue, it stages a conversation between a fearful parishioner and a minister who urges him to fear God rather than celestial signs:

“Then when Comets shall blaze, when the elements shall melt with fervent heat … you will have a building of God, an house not made with hands, eternal in the heavens.” The tract concludes with a direct appeal to readers: “Believe in the Lord Jesus Christ and be saved.”

Lincoln and Edmands was a leading early 19th-century Boston publisher of Baptist tracts, and this edition is scarce. WorldCat records copies at the American Antiquarian Society and the Lilly Library, both with a press variant misnumbering page 12 as “21.” The present copy, by contrast, is corrected.

A rare survival of religious and cultural history sparked by one of the most famous comets ever seen.
