- 1626
1626. Engraved allegorical frontis., fine engraved port. of the Duke of Bracciano, engraved vignette on title, & very many finely engraved illus. in the text (some full-page) depicting the author’s observations of sunspots and the telescopes he used. 20 p.l. (incl. frontis.), 784 pp., one blank leaf, [36] pp. Large thick folio, cont. stiff vellum over boards (a few quires lightly discolored). Bracciano: [Privately Printed by] A. Phaeus, 1626-30.
First edition of Scheiner’s greatest work; this magnificent book, very rare on the market today, is the most richly and superbly illustrated astronomy book published in the first half of the 17th century. It describes and depicts Scheiner’s observations of sunspots and his telescopes.
In 1611, Scheiner constructed a telescope with which he began to make astronomical observations, and in March of that year, he detected the presence of spots on the sun. Scheiner’s claim to the discovery of sunspots, independently of Galileo, was the origin of one of the most famous and heated controversies in the history of science.
This book contains the summation of Scheiner’s observations of the sun. He confirmed his method and criticized Galileo for failing to mention the inclination of the axis of rotation to the plane of the ecliptic.
Of great importance is Scheiner’s discovery of the helioscope, described here. This was the first Keplerian telescope in use, consisting of two convex lenses; it was also the first to use colored glass in the eyepiece. Kepler himself had only considered the telescope theoretically.
Scheiner writes here that he had used the Keplerian telescope 13 years before in the presence of the Archduke Maximilian.
The quality of the engravings in this book is exceptional. There are many fine illustrations of the telescope and its parts, lenses, fittings, etc. Rosa Ursina was printed on the private press established by Paolo Giordano Orsini, Duke of Bracciano, a great patron of astronomy, at his castle at Bracciano.
A very fine copy of a book that is very difficult to find. Minor foxing, a few unimportant tears, and a few small defects to the binding. Early German manuscript shelf label; “M.W.” (19th-century bookplate with coronet).
❧ Cinti 79. D.S.B., XII, pp. 151-52. King, The History of the Telescope, pp. 40-45. Linda Hall Library, Jesuit Science in the Age of Galileo, 6.
