The composition of an instrument, for the houre of the night: which is also a perfect Dial for the day.
THe takinge of an Altitude supposed, I coulde exactly in fewe (and that without an instrument) satisfie. And for want of that knowledge, make vpon a playn bourde, or rather fine plate, a circle: the byggar the better: part it into 360. porcions, thus.
The circle made, diuide it in 6. not mouing the compasse: then euery of them in 6: and eche of those last in 10: so haue you 360. par tes. Then Character it, begynning at the North thus, 10. 20. 30. &c. (as in the figure) towarde the East, ending with 360. Nowe laye a ru∣ler on the centre, euen with some diuisions, drawinge thorowe to the extremes of the circle, a lyne. Then crosse that with an other. These two must diuide your circle in 4. equal partes: which lynes shewe the verye Easte, VVest, Northe, and Southe, when by a Meridian or square Diall, with a nedel rectified, they are placed. Now to ende, set a small streyghte wyre, a foote or more long, plumme vprighte in the centre: and there fasten it. Thus this instrumente is finisshed, to be fixed about your house, equidistāt or leuil with the Horizon: ha∣uinge a nedell, yf ye lift, in it, trewlye to plage it, when and where you will. That it maye be also a Dial, you muste pull streyghte lynes from the centre, to euery fyf∣tēth part: decking them with Characters in the inwarde margent, conueniently as ye see the figure. Thus whan the Sunne shyneth, the shadow of the wyre, sheweth the trew houre &c. beynge trewly plaged, wel placed, and rered, as foloweth.
