The art of dialling performed geometrically, by scale and compasses: arithmetically, by the canons of sines and tangents: instrumentally, by a trigonal instrument, accommodated with lines for that purpose; the geometrical part whereof is performed by projecting of the sphere in plano, upon the plain it self, whereby not only the making, but the reason also of dials is discovered. The second edition diligently corrected and enlarged, with a second way of geometrical dialling, very easie, plain, and universal. By William Leybourn, philomath Università degli Studi di Salerno

The art of dialling performed geometrically, by scale and compasses, Two several ways. Arithmetically, by the canons of signs and tangents: instrumentally, by a trigonal instrument, accommodated with lines for that purpose: the geometrical part whereof is performed by projecting of the sphere in plano, upon the plain it self, whereby not only the making, but the reason also of dials is discover'd. The third edition, enlarged. With a supplement, shewing how geometrically and mechanically to insert into all sorts of sun-dials, such circles of the Sun's course as gives the hour and length of the day, according to the account of several countries, &c. And to project and reflect hour-lines upon all sorts of superficies, plain or curved, without any regard had to their standing, either in respect of declination, or inclination.

A second way of geometrical dialling very easie, plain and universal. The third edition. To which is added a supplement; shewing, how by scale and compasses to inscribe such circles of the sphere into sun-dial-plans that shall shew (besides the hour of the day) the diurnal motion of the sun; his place in the zodiack; the time from his rising, and setting; Babilonian, Italian, and Jewish hours; the point of the compass upon which the sun is at any time of the day, and the proportions of shadows to their heights. Also, a general and easie way to project hour lines upon all kinds of supersicies without any regard had to their standing. And, how from a glass horizontally plac Università degli Studi di Salerno
