NAPIER, John (1550-1617). Logarithmorum canonis descriptio. Lyon: B. Vincent, 1620.
First Lyon edition, second issue, of Napier's discovery of logarithms, one of the greatest milestones in the history of Western science. It enormously advanced the art of calculation and was immediately and successfully applied by Kepler to astronomy. Cf. PMM 116.
3 parts in one volume, quarto (204 x 139mm). Each part with separate title, first title printed in red and black, woodcut diagrams (browning, small waterstain on L2 in second part). Contemporary vellum, titled in manuscript on spine (small stains, some loss of vellum at spine). Provenance: label removed from spine, evidence of removed bookplate on pastedown, erased inscription on title and two other places.
