A08583	The description and use of the double horizontall dyall	Oughtred, William, 1575-1660.	1632 (1632)	STC 18899C.5; ESTC S3161	8,104	18

any two of the parallels imagine in your in inde and estimate with your eye another parallel through that point between those two parallels keeping stil the same distance from each of them As in the first of the three former examples The circle of the Sunnes course upon the 11. of August shall be the very sixt circle above the Equinoctiall toward the center In example 2. The circle of the sunnes course upon the 24. of March shall be an imaginary circle between the lecond and third parallels still keeping an halfe of that space and one fift part more of the rest from the second In example 3. The circle of the Sunnes course upon the 13. of Novemb shall be an imaginary circle betweene the tenth and eleventh parallels below the Equinoctiall still keeping one quarter of that space froÌ„ the tenth IIII. Vse To find the rising and setting of the sunne every day Seeke out as was last shewed the imaginary circle or parallel of the sunnes course for that day and marke the point where it meeteth with the horizon both on the East and West sides for that is the very point of the Sunnes rising and setting that same day and the hower lines which are on both sides or it by proportioning the distance reasonably according to 15. minuts for the quarter of the hower wil shew the hower of the Sunnes rising on the East side the Sunnes setting on the West side V. use To know the reason and manner of the Intreasing and decreasing of the dayes nights throughout the whole yeare When the Sunne is in the Equinoctiall it riseth and setteth at 6. a clock for in the instrument the intersection of the Equinoctial and the Ecliptic with the Horizon is in the sixe a clocke circle on both sides But if the sunne be out of the Equinoctiall declining toward the North the intersections of the parallel of the sunne with the horizon is before sixe in the morning and after 6. in the evening and the diurnal arch greater then 12. howers and so much more great the greater the northerne declination is Againe if the sunne be declining toward the South the intersections of the parallel of the Sunne with the horizon is after sixe in the morning and before sixe in the evening and the diurnal arch lesser then 12. howers and by so much lesser the greater the southerne declination is And in those places of the Ecliptic in which the Sun most speedily changeth his declination the length also of the day is most altered and where the Ecliptic goeth most parallel to the Equinoctial changing the declination but little altered As for example when the sunne is neere unto the Aequinoctiall on both sides the dayes increase and also decrease suddainly and apace because in those places the Ecliptic inclineth to the Equinoctial in a maner like a streight line making sensible declination Againe when the sunne is neare his greatest declination as in the height of Summer and the depth of winter the dayes keepe for a good time as it were at one stay because in these places the Ectiptic is in a manner parallell to the Equinoctiall the length of the day also is but little scarce altering the declination And because in those two times of the yeare the Sunne standeth as it were still at one declination they are called the summer solstice and winter solstice And in the meane space the nearer every place is to the Equinoctial the greater is the diversity of dayes Wherfore we may hereby plainly see that the common received opinion that in every moneth the dayes doe aequally increase is erroueous Also we may see that in parallels aequally distant froÌ„ the Aequinoctiall the day on the one side is aequall to the night on the other side VI. Vse To find how farre the sunne riseth and setteth from the true East and west points which is called the sunnes Amplitude ortive and occasive Seeke out as was shewed in III. use the imaginary circle or parallel of the suns course and the points of that circle in the horizon on the East and West sides cutteth the degree of the Amplitude ortive and occasive VII Vse To finde the length of every day and night Double the hower of the Sunnes setting and you shall have the length of the day and double the hower of the Sunnes rising and you shall have the length of the night VIII Vse To finde the true place of the sunne upon the diall that is the point of the instrument which answereth to the place of the sunne in the heavens at any time which is the very ground of all the questions following If the dyall be fixed upon a post Looke what a clocke it is by the outward dyall that is looke what hower and part of hower the shadow of the slanting edge of the stile sheweth in the outward limbe Then behold the shadow of the upright edge and marke what point thereof is upon that very hower and part in the inner dyall among the parallels that point is the true place of the Sun at the same instant If the dyall be not fixed and you have a Meridian line noted in any window where the Sun shineth place the Meridian of your dyall upon the Meridian line given so that the top of the stile may point into the North and so the diall is as it were fixed wherefore by the former rule you may find the place of the sunne upon it If the dyall be not fixed neither you have a Meridian line but you know the true hower of the day exactly hold the dyal even and parallel to the horizon moving it til the slanting edge of the stile cast his shadow justly upon the time or hower given for then the dyall is truly placed as upon a post Seek therfore what point of the upright shadow falleth upon that very hower and there is the place of the Sunne But if your dyall be loose and you know neither the Meridian nor the tyme of the day Frist by the day of the month in the Ecliptick find the sunnes parallel or diurnall arch for that day then holding the dyall leuell to the horizon move it every way untill the slanting shadow of the stile in the outward limb and the upright shadow in the sunnes diurnall arch both shew the very same hower and minut for that very point of the sunnes parallel which the upright shadow cutteth is the true place of the Sunne on the dyal at that present But note that by reason of the thicknes of the stile and the bluntnesse of the angle of the upright edg the Sunne cannot come unto that edge for some space before and after noone And so during the time that the sunn shineth not on that upright edge the place of the Sunne in the dyall cannot be found Wherefore they that make this kind of double dyall are to be careful to file the upright edge of the stile as thinne sharpe as possible may be

That which hath heere bin taught concerning the finding out the sunnes true place in the dyal ought perfectly to be understood that it may be readily and dexterously practized for upoÌ„ the true performance therof dependeth all that followeth IX Vse To find the hower of the day If the dyall be fastened upon a post the hower by the outward dyall or limbe is knowne of every one the upright shadow in the suns parallel or diurnal arch wil also shew the very same hower But if the dyall be loose either hold it or set it parallel to the horizoÌ„ with the stile pointing into the North and move it gently every way untill the hower shewed in both dyals exactly agreeth or which is all one find out the true place of the sunne upon the dyall as was taught in the former question for that point among the hower lines sheweth the hower of the day X. Vse To find out the Meridian and other points of the compasse First you must seeke the true hower of the day by the last question for in that situation the Meridian of the dyall standeth directly North and South and the East pointeth into the East and the west into the west and the rest of the points may be given by allowing degr 11. Â¼ unto every point of the compasse XI Vse To find out the Azumith of the sunne that is the distance of the Verticall circle in which the sunne is at that present from the Meridian Set your dyall upon any plaine or flat which is parallel to the horizon with the Meridian pointing directly North and South as was last shewed then follow with your eye the upright shadow in a streight line till it cutteth the horizon for the degre in which the point of intersection is shall shew how farre the suns Azumith is distant from the East and west points and the complement thereof unto 90. shall give the distance therof from the Meridian XII Vse To find out the Declination of any Wall upon which the sunne shineth that it how farre that wall swerveth from the North or South either Eastward or Westward Take a board having one streight edg a line strickeÌ„ perpeÌ„dicular upoÌ„ it apply the streight edg unto the wal at what tyme the sun shineth upoÌ„ it holding the board parallel to the horizon Set the dyal thereon move it gently every way untill the same hower and minute be shewed in both dyals and so let it stand then if the dyal have one of the sides parallel to the Meridian strike a line along that side upon the board crossing the perpendicular or else with a bodkin make a point upon the board at each end of the Meridian and taking away the instrument from the board and the board from the wall lay a ruler to those two points draw a line crossing the perpendicular for the angle which that line maketh with the perpendicular is the angle of the declination of the wall And if it be a right angle the wall is exactly East or west But if that line be parallel to the perpendicular the wall is direct North or South without any declination at all You may also find out the declination of a wall if the dyall be fixed on a post not very farre froÌ„ that wal in this maner Your board being applyed to the wal as was shewed hang up a thred with a plummet so that the shadow of the thread may upon the board crosse the perpendicular line make two pricks in the shadow runn instantly to the dyall and looke the horizontall distance of the sunnes Azumith or upright shadow from the Meridian Then through the two pricks draw a line crossing the perpendicular and upon the point of the intersection make a circle aequal to the horizon of your instrument in which circle you shall from the line through the two pricks measure the horizontall distance of the upright shadow or Azumith from the Meridian that way toward which the Meridian is draw a line out of the center to the end of that arch measured and the angle which this last line maketh with the perpendicular shal be aequall to the declination of the wall XIII Vse How to place the dyall upon a post without any other direction but it selfe Set the dyall upon the post with the stile into the North as nere as you can guesse then moue it this way and that way till the same hower and minute be shewed both in the outward inward dyals by the several shadowes as hath bin already taught for then the dyal standeth in its truest situation wherefore let it be nailed downe in that very place XIIII Vse To find the height of the Sun at high noone every day Seeke out the diurnal arch or parallel of the sunnes course for that day by use III. and with a paire of compasses setting one foot in the center the other in the point of intersectioÌ„ of that parllel with the Meridian apply that same distance unto the samidiameter divided for that measure shall therein shew the degree of the sunnes altitude above the horizon that day at high noone XV. Vse To find the height of the sunne at any hower or time of the day Seeke out the diurnall arch or parallel of the sunnes course for that day and marke what point of it is in the very hower minute proposed And with a paire of compasses setting one foot in the center and the other in that point of the parallel apply the same distance unto the semidiameter divided for that measure shall shew the degree of the sunnes altitude above the horizon at that time And by this meanes you may find the height of the sunne above the horizon at every hower through out the whole yeare for the making of rings and cylinders and other instruments which are used to shew the hower of the day XVI Vse The height of the sunne being given to finde out the hower or what it is a clocke This is the converse of the former seeke therefore in the semidiameter divided the height of the sunne given And with a payre of compasses setting one foot in the center and the other at that height apply the same distance unto the diurnall arch or parallel of the sunne for that day for that point of the diurnall arch upon which that same distance shall light is the true place of the sunne upon the dyal and sheweth among the hower lines the true time of the day XVII Vse Considerations for the use of the instrument in the night In such questions as concerne the night or the time before sunne rising and after sunne setting the instrument representeth the lower hemisphere wherin the southerne pole is elevated And therefore the parallels which are above the Aequinoctiall toward the center shal be for the southerne or winter parallels and those beneath the Aequinoctiall for the Northerne or Summer parallels and the East shall be accounted for West and the west for East altogether contrary to that which was before when the instrument represented the upper hemisphaere XVIII Vse To find how many degrees the sunne is under the horizon at any time of the night Seeke the declination of the sun for the day proposed by use II. And at the same declination on the coÌ„trary side imagine a parallel for the Sun that night and marke what point of it is in the very hower minute proposed And with a paire of compasses setting one foot in the center and the other in that point of the parallel apply that same distance unto the semidiameter divided for that measure shall shew the degree of the sunnes depression below the horizon at that time XIX Vse To find out the length of the Crepusculum or twylight every day Seeke the declination of the sun for the day proposed by use II. And at the same declination on the coÌ„trary side imagine a parallel for the sun that night And with a payre of compasses setting one foot in the center and the other at 72. degrees upon the semidiameter divided apply that same distance unto the sunnes nocturnall parallel for that point of the parallel upon which that same distaÌ„ce shal light sheweth among the hower lines the beginning of the twilight in the morning or the end of the twilight in the evening XX. Vse If the day of the month be not knowne to find it out by the dyall For the working of this question eyther the dyall must be fixed rightly on a post or else you must have a true Meridian line drawne in some window where the sun shineth wherefore supposing the dyall to be justly set eyther upon the post or upon the Meridian Looke what a clock is it by the outward dyal and observe what point of the upright shadow falleth upon the very same minute in the inner dyall and through that same point imagine a parallel circle for the sunnes course that imaginary circle in the Ecliptic shall cut the day of the moneth These Instrumentall dyalls are made in brasse by Elias Allen dwelling over against St. Clements Church without Temple-barre FINIS
