In Italian and Latin, c.155 leaves , 4to (185 x 140mm) , (some staining and darkening ff.1-6). Modern half vellum. Box. Provenance : the contemporary armorial on the title page is for the Calcagnini family of Ferrara, beneath the escutcheon is written ‘Comitis Hieronymus Calcanei’, presumably the Girolamo Calcagni of the text; beneath this is a faint inscription in Latin by ‘Marsilii Antonii’ dated 1725.

An attractive 17th-century astronomical treatise in a fine hand, featuring many neat pen and ink diagrams, perhaps the author’s own copy: Girolamo Calcagni, one of the two interlocutors at the centre of the text, is represented by his arms on the title page. An addendum, in the same hand as the text, to one of the blank leaves at the end of the manuscript, dated 20 February 1643, lists two publications that may have influenced the author: Regiomontanus’ De cometis of 1472 and Girolamo Sirtori’s Telescopium of 1618, the first book published on telescopes.
