London : Awnsham Churchill, 1682 A good copy of the 1st edition in later full leather binding with frontispiece and 23 full page plates, of which 10 are folding. Leybourn's first work on Dialing was published in 1669; it's popularity (particularly given the use of sun-dials and astrolabes by the navy at that time) led to this expanded folio version, funded by subscription. William Leybourn was a leading practical mathematician and authored a number of works on surveying, Gunter's Line and measuring tables. This copy has been rebound fairly recently in a full pigskin binding with raised bands and title and author labels. New endpapers have been added, and the frontispiece relaid and repaired (there was loss to the side edge and a little damage to the portrait).
