The art of dialling performed geometrically, by scale and compasses: arithmetically, by the canons of sines and tangents: instrumentally, by a trigonal instrument. The geometrical part whereof is performed by projecting of the sphere in plano, upon the plan it self, whereby not only the making, but the reason also of dials is discovered. 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, ....
