Astronomy.- [Edwards (John)] Cometomantia. A Discourse of Comets, first and only edition, initial blank leaf present, some marginal staining, lacking rear endpapers, contemporary calf, worn and piece of leather missing from upper cover, exposing board beneath, 8vo, [Wing E199], Printed for Brab. Aylmer, 1684.

⁂ Rare in commerce, we can trace only two copies at auction since 1946, including one sold in these rooms in 2022 (£1500) in worse condition. The book treats both the physics and meaning of comets, discussing (as the title page indicates) their "substance, place, time, magnitude, motion, number, colour, figure, kinds, names, and more especially their prognosticks, significations and presages."
