c1780s ORIGINAL MANUSCRIPT NOTES ON VARIOUS ASTRONOMY TOPICS HANDWRITTEN IN A FINE CALLIGRAPHIC HAND

On offer is a fascinating group of 15 pages of notes on eight [8] leaves regarding a variety of astronomy subjects. Handwritten on watermarked laid paper by an unknown scrivener, the papers suggest a date of circa 1780s mentioning the expected return of a comet in 1789 on one of the pages. [Other dated material in the original archive confirm this.] The beautifully written 8" X 10" double-sided astronomy topics include: Comets, such as the Comet of 1105, 1680 and Halley's Comet; Perihelion; Alhelion; The Planets Mercury (mentions the heat the inhabitants must feel), Venus, Jupiter, and Mars and The Moon. The pages not continuous and jump from topic to topic appear to be portions of a longer 47 page manuscript. Overall Fine.
