Scientific Instruments.- Manzini (Carlo Antonio) L'occhiale all'occhio dioptrica pratica, woodcut vignette to title with a telescope, woodcut illustrations in text, woodcut tail-pieces and decorative initials, lacking engraved portrait of Eustachio Divini, some staining and spotting, 18th century carta rustica, later paper label to foot of spine, spine lightly browned, some staining, [Krivatsy 7389; Riccardi ii, 96; Wellcome II, p.48; V. Ilardi, Reinassance Vision from Spectacles to Telescope, Philadelphia 2007], small 4to, Bologna, Heirs of Benacci, 1660.⁂ First and only edition of this important treatise on practical optics and lens making, once owned by Eustachio Divini (1610-1685), a leading 17th century manufacturer of optical instruments, who is referenced in the work. Indeed, Manzini in his preface credits him with being the first to perfect the art of telescope making. It is possible that the volume was sent to Divini pre-publication, accounting for the missing portrait of the recipient, which was printed separately on different paper. Provenance: Eustachio Divini (ink ownership inscription to title); ink monogram combining the letters O and K at foot of title; Giorgio Tanarroni (modern bookplate).
