First edition of Euclid's geometry, the first substantial mathematical work to be printed. The Elements "exercised an influence upon the human mind greater than that of any other work except the Bible" (DSB). Euclid was known in antiquity simply as "the Writer of the Elements." His work was a magisterial compilation of mathematical knowledge to date, including his proof of the Pythagorean theorem (Book I, proposition 47). Books I-XIII are accepted as genuine; Book XIV is attributed to Hypsicles and Book XV to Isidorus Milesius.
Ratdolt's Euclid is one of the most technically ambitious of all Venetian incunables. It is widely acknowledged as a tour-de-force of Renaissance printing, a masterpiece of typographical ingenuity. It yet remains a matter of some bibliographic debate whether the diagrams were achieved with woodcuts or metalcuts. Bühler noted a stop-press correction on o8r; the present copy has the corrected version. In need of cleaning and rebinding, but unpressed and notably well-margined, without shaving to the all-important diagrams. See Curt Bühler in Gutenberg Jahrbuch 1966, pp 102ff; HC *6693; Goff E113; GW 9428; Norman 729; PMM 25.
Provenance: about two dozen lines of early manuscript marginalia primarily in Books II-III; unidentified shelf label "425" on c1r.
