DRYANDER, JOHANNES.

Cylindri Usus et Canones...,

      Im Pressum Marpurgi per Andream Kolbium, Calend. Junii, Anno &c 1st and sole Latin edition of this work, which appeared in a Germanûedition in 1537. Until definitive evidence confirms tne existence ofûSchoener's 'Horarii Cylindri Canones' of 1515, this little volume remainsûthe first printed work devoted to the pillar dial. In it Dryander makesûclear that he is building on the work of others, notably SebastianûMuenster and Oronce Fine, and in his justification of this latin editionûhis dedicatory letter prays in aid others who have published likewiseûin latin - Peuerbach, Regiomontanus, Apian, Schoener, and also Copernicus, whose 'De revolutionibus'ûhad appeared only a few months earlier. The folding plate, whichûillustrates the setting out of the dial, together with the pattern for theûgnomon, is the same as used in the german edition of 1537 - retaining bothûthe date and original german text. It appears to be often missing.ûDryander (germ. Johann Eichmann)ûtaught medicine and mathematics at the recently founded University ofûMarburg, where one of his colleagues was Burkard Mithob(ius). Both menûdeveloped a range of astronomical instruments, which wereûdescribed in a series of small publications published by the newly establishedûpresses in Marburg. They are all very rare. Unknown to Poggendorff, H&L,ûSotheran, Tardy, Zinner (who only knew of the german edition), Adams and Hamel.ûThis is the Honeyman copy. We have traced a further 8 copies of which 1 isûthe german edition, and 3 appear to lack the folding plate. Small 8vo., (145mm x 95mm), pp: 15 leaves (unpaginated), full page woodcut at B2 verso, 1 folding woodcutûplate, sl. browned, later vellum gilt. COLLATION: A8 - B7.
