      [Venetius, 1478.]. Small 4to, 20.5 cm., collating a-b8, c-d6; e-f10, this copy with 45 (of 48) leaves!lacking e2, and e9-10); 25 lines; types 5:109bR (text), 6:65G (diagram text); incipits to each part pprinted in red; 6 (of 11) woodcut diagrams (2 with hand-coloring), woodcut initials (mostly hand-colored), full contemporary and probably original limp vellum, old manuscript titling on spine, and with a wallet-style wrap-around flap, the vellum worn and soiled. Beginning at ff. [29]: Gerardi cremonensis uiri clarissimi Theorica planetaru[m] feliciter incipit. The Theorica planetarum is usually considered to be by the Cremona astrologer Gherardo da Sabbioneta, although some authorities ascribe it to the Gerardus Cremonensis who died 1187. See DSB, Supplement, p. 189 for a summary of the evidence. Both works were first printed in 1472. In spite of the missing leaves, this is a most interesting copy, having been annotated by the rubricator and colorist, with 11 lines of notes by him on the verso of the blank leaf preceding a1, and notes in the margins of 25 of the pages of the Sphaera mundi, and another 3 more lines of notes on the blank leaf following f10; also with a dated ownership inscription of Caroli Malagesse Benigni, 1636, with his note "Impressum 1478" in ink on the first flyleaf, and with a calligraphic notation on verso of the second rear flyleaf: "Fur cave ne nostrum rapiat tua dextera librum, Ni dare vis lignis colla tenenda tribus: ("Thief, watch that your hand doesn't snatch our book away, Unless you wish your neck to be restrained by three wooden sticks" [i.e., the yoke].
