The houres in every Circle , are continued on both sides of the Meridian line , so farre as the houre-lines for the Sunne doe extend , that so the Dyall might serve generally for all times of the yeare ; and though the houre of 12. falleth twice in some of them , yet may they both be usefull at one time of the yeare or other ; for to place in such houres onely as shall happen to be of use , and neither more nor lesse , is a thing I conceive not to bee certainely done by reason of the uncertaine rising and setting of the Moone , and her uncertaine departure from the rayes of the Sunne .

Having noted downe the houres in every circle ( as in the second figure ) adde to each circle one or two inward circles , making one or two convenient spaces for the placing in of little lines or strokes , for the houres and their parts ( according to the usuall manner ) and the figures belonging to them : but in the latter way you must adde to each circle , three other inward circles , making three severall spaces for the three rankes of figures belonging to every circle , ( as you may see in the third and last figure ) because the houre-lines of every circle ( as I sayd before ) be here of a threefold denomination : and it is necessary for you so to order and contrive the circles on your plane , as that there may be left a convenient space betweene every severall Dyall or circle of houres , to distinguish betweene them , and not to mingle and confound them one with another .

The parts of every houre necessary to be placed on the Dyall ( though we have put none here , partly to avoyd tediousnesse in the worke , and some charge in cutting the figures , and partly because the are needelesse in this place ) may be those which we have formerly used , or better it were for common use to have each houre divided into some equall number of parts , as foure or eight parts , as is usually done in most Sun-dyals ; for before we divided each houre into five parts , as being the fittest number for the more easie and exact making of the Dyall .

The outermost circle of all , belonging to the fifteenth day of the Moone or day of opposition , serveth aswell for the Sunne , the houre-lines thereof being rightly disposed for the Sunne . For the Moone , on the day of her coujunction with the Sunne , commeth to the Meridian much about the time that he doth , and in the day of her opposition to the Sunne , she commeth to the sayd place at the opposite time or thereabout , when the Sunne is in the North point of the Meridian circle , under the ear●h ▪ or our Horizon , that is , at our Mid-night or 12. of the clocke ( as the former Table sheweth ) and then the same Dyall which serveth to shew the houre of the day by the Sunne , serveth likewise to shew the houre of the night by the Moone , though not alwayes so exactly , yet without any difference to be regarded in common use ( as I have oftentimes observed ) but at other times it cannot be so , because the time of the Moones aforesayd mediation or culmination , is not alwayes the same , but altereth on every day , and therefore that Dyall which should serve to shew the houres or times of any other night by the Moone , must ( of necessitie ) be altered , and the houte-lines bee otherwise ordered and disposed , or else why should not the Moone in any night when she shineth , shew the true houres thereof upon any true Sunne-Dyall by the stilar shadow , aswell as the Sunne sheweth the true houres of any day by the same ; which thing , how farre it is from being so , I thinke there is scarcely no ordinary man that doth not know it ; the reason thereof being ( as I shewed before ) because the Moone doth not alwayes observe the same times with the Sunne , in her rising , Southing , and setting .

These severall Dyals or circles of houres , may not onely be delineated upon the Horizontall Plane , to shew the time of the night by the Moone , but also upon all other planes by the same reason and rule , ( and therefore we have here entitled it , Lunar Horologiographie , that is , The Description of Dyals for the Moone ) and most readily upon the Equinoctiall Plane , by reason of the equality of the horariall angles : And in the direct Meridian and Polar Planes , where the Solar houre-lines are parallels , there also the Lunar will be parallels ; and in stead of those fifteene concentricall circles formerly used , here must bee fifteene parallell right lines , of which the equinoctiall line of the Plane , may very fitly be one , which may ( if you please ) serve for the fifteenth day of the Moone , and so will serve continually for the Sunne by the reason aforesayd : So the seven Parallels falling under the sayd line , may then fitly serve for the seven dayes next enfuing the day of her change and Full , and the seven Paralells above the sayd line , for the seven dayes next before the Full , and the change next following : or you may begin at the uppermost parallell on the Plane , and account that for one day and sixteene dayes of the Moone , and so going downewards , the lowest parallell will be for fifteene and thirty dayes , and so for the Sunne , and then the equinoctiall line or middle parallell shall be for eight and 23. dayes , for you may begin with what parallell you will : then drawing the common houre-lines of these Planes , and dividing each hour● into five parts ( as before ) the houres for the Moone are set off from the houre-lines of 6. in the one and 12. in the other on both sides thereof upon their proper parallels , ( as farre as the houre-lines for the Sunne doe extend ) with as much facility as in any other Plane whatsoever , the Equinoctiall plane being excepted ; so that you bee carefull to place the right houres in these planes : Having thus set downe the houres ( and parts if you please ) draw to each Parallell line another parallell including a convenient space betweene them , wherein to draw little lines or strokes for the houres and their parts , and to place the figures belonging to the houre-lines or strokes : But for that I shewed before , how this might bee performed by five circles in the Horizontall plane , so by the same reason it may here be performed by five parallells onely , for then each parallell serveth for sixe dayes , and the houre-lines of each parallell are of a threefold denomination , and then you must draw to each parallell line , three other parallels , that so there may be three fitting spaces made for the placing of three rowes of figures which belong to the houre-lines of every parallell , as was done by circles in the Horizontall plane ; and in the delineating of any of these Dyalls , it were convenient for you first to draw the common ( or Solar ) houre-lines belonging to the plane , obscurely with the point of your compasse or such like thing upon your plane , by which you may easily discerne whether you worke rightly or not : But to deliver any figure here concerning these last mentioned planes I thinke it to be needelesse , because if the working upon the former be rightly understood , the working upon these latter and likewise upon all other Planes may easily be understood by the same reason : And as for the stile belonging to to these last named Planes , it is necessary that the same be made full as broad as the Plane of the houre-lines , ( or if it were a little broader in the top , it were not amisse ) that so the shadow thereof may alwayes extend as farre as the parallell lines on the Plane ; for though a straight round pin will serve in these Planes for a stile for the Sunne , yet it will not for the Moone , by reason of the varietie of Dyals on one and the selfe sam● Plane , all differing one from another : But indeed none other is so commodious for common use as the Horizontall Dyall , which may ( most easily ) be fitted for use two manner of wayes : For it may be either alwayes fixed abroad , like unto the common horizontall Sun-Dyall , and so be immoveable , or else not fixed , but to be removed up and downe at pleasure , and then having a Magneticall Needle placed in a Boxe after the usuall manner ( whose Meridian line ought to be drawne therein , according to the deflection or variation of the Needle in the place of observation ) to be affixed to some side thereof , it may bee truely placed thereby , any night when it should be used , being holden or set precisely horizontall ; or ( for want of such a Needle ) they that have an horizontall Sunne-Dyall about their house truely placed , may make a shift to use it well enough , by laying it flat upon that Dyall , and then applying one side the●eof to the side of the cocke or ftile of that Dyall , in such sort that the Meridian line of the one may be paralell to the Meridian line of the other . But indeed the most absolute way of all , were to have it made in brasse ( which may be done by Mr. Elias Allen dwelling without Temple Ba●re , over against St. Clements Church , London , who maketh all sorts o● Mathematicall Instruments and also horizontall Sunne-Dyalls in brasse ) and fixed alwayes upon a poast , or rather made upon a faire white stone , where the strokes for the houres and their parts and the figures belonging to them being done in blacke or other such notable colour , might be more perfectly discerned than in the other : So that then onely knowing the day of the Moone , ( which may be knowne by any Almanacke ) you have no more to doe , ( the Moone shining on the Plane ) but to looke out the circle which is appropriated to that day , and the shadow of the stile will presently give you the houre or time of the night , if your Dyall be rightly made and placed : And it would be very comely and convenient to have the stile to this Dyall made so , as it should touch the plane in those places onely where it is let into the same , that is , betweene the center and the circle next unto it , and againe a little about the outermost circle which is furthest from the center , that so the stroakes for the houres and their parts , and the figures which fall upon or very neere the Meridian line , might not be hidden and defaced by the stile .

But because houre-lines may be placed generally upon all planes ( as I sayd before ) to shew the houres of the night by the Moone ; it would be an excellent way to have a Lunar Dyall drawne on glasse and placed in a window after the manner of those Sunne-Dyalls which are most accurately made by my loving friend Mr. Baptist Sutton , dwelling at the upper end of Chauncery Lane , neere Holborne ( being the author of the ensuing worke or Addition ) who likewise will be able to performe these as accurately as the other , if it shall be required of him : For there the plane of the Dyall being of a transparent matter , and intercepted ( as a meane object ) betweene the eye and the Moone , the houre-stroakes and figures , together with the shadow of the stile , may bee thereupon more perfectly and speedily discerned , than upon any other kinde of Plane whatsoever ( and therefore I thought it not amisse to give notice thereof ) but it is well knowne that the shadow which is caused by the Moone , cannot be altogether so perfectly discerned as that which is caused by the Sunne , because the light of the Moone is not so perfect as the light of the Sunne , and therefore the time of the day may be somewhat more readily perceived on the Dyall by the stilar shadow , than the time of the night ; yet it may be very easily discerned thereby , especially when the Moone shineth out very bright .

And now , this our Horizontall Dyall I conceive ( and I thinke , that any man of understanding will acknowledge ) to be farre more easie and ready in use , than that Lunar Dyall which Mr. Fale hath long agoe described , in his booke of Solar Horologiographie , whose position must be in direct Paralellisme to the Equinoctiall circle of the Sphere , making the same angle ( of inclination ) with the Plane of the Horizon , which that doth , being the complement of the Latitude or Polar altitude , and therefore but few men know how to make use thereof in comparison of them that doe not know ; and it must needes bee troublesome also to those that doe know how to place the same rightly , because they must stand and apply a Quadrant together with a needle to it every night when they would use it , unlesse the same stand alwaies fixed abroad in its due position ; and if it so doe , yet the unskilfull sort cannot well tell how to make use of it , by reason ( it consisting of two severall parts or plates ) of the inward moveable part thereof , turning about within the outmost plate , and upon which the houre-lines are drawne , whose Index , ( or long tooth , as he termeth it ) being fastned at the houre of 12. must be turned to the day of the Moone noted on the outermost or fixed part , and to the houre of the change ( as he saith ) accounting from 12. of the clocke ; in which he hath not sufficiently expressed the meaning thereof , for such as are but meanely skilled in these things , to understand , and so ( as I conceive ) hath not well declared the making and use of the same . Vpon the outermost or fixed part , hee draweth a circle , which hee divideth into 30. parts for the thirty dayes of the Moone , after this manner : Now because ( saith he ) the Moone finisheth her course in 29. dayes , 12. houres , and 44. minutes , ( that is , from the Sunne , being in a meane conjunction with him , till she be with him againe by the like conjunction ) part or divide the aforesayd circle into 30. parts , so as 29. of them being equall , the thirtieth or last must not be so great as one of the other parts by ⅓ , that is , it must containe ⅔ of one of them ; by which account ( if it were true ) the Moone should finish her sayd course in 29. dayes , and 16. houres , ( which make ⅔ of the naturall day ) whereas the same is but 29. dayes , and 12. houres , or ½ of the day naturall , and about ¾ of an houre over , and therefore it doth not consequently follow , that the last part should containe ⅔ of one of the rest , but rather ½ onely : Indeed ( for mine owne part ) I must confesse , I never made tryall of this Dyall , and therefore can say the lesse of it , neither doe I know whether the same were of his owne devising or not ; But sure I am that this our Horizontall Dyall is every way as exact as that , and serveth to a more generall use , it being of use and delight for all sorts of men , and more especially ●uch as know not how to finde the houre of the night artificially by other wayes : for if they can but know how to get the true age of the Moone ( which is easily done by an Almanacke , as I sayd before ) they may as easily obtaine the time of the night by this Dyall ( or the like made upon any other Plane , when the Moone shineth thereupon ; and that sufficiently enough ) as the time of the day by any Sunne-dyall when the Sunne shineth on the same : But if any list to make use of such a kind of Dyall , as that of Mr. Fales , lately mentioned , they may use another way to finde the time of the night more exactly thereby : For the houre-lines being drawne upon the moveable or turning plate or wheele ( as before is sayd ) which should now be so large as each houre may be distinctly divided into such a number of parts , as that you may guesse at any one minute thereupon , ( which may conveniently 15. or 20. parts , for then each part will containe but foure or three prime minutes of time ) If they can have a Table of the Moones comming to their Meridian artificially and exactly calculated for every day in the yeare , and so for every yeare severally ( which in some yeares is to be found in one Almanacke or other , if trust may be given to them ) then to make use of this Dyall in any night of the yeare when the Moone shineth , they must looke out that day in the sayd Table , and right against it , under its proper moneth is set the houre and minute of the Moones comming unto the Meridian for that day and place : then the Dyall being rightly placed if they bring that houre and minute noted on the inward or moveable part to the Meridian line noted on the outtermost or immoveable part , and so let the houre-lines in that position , the shadow of the stile shall shew the houres of that night exactly , without having any regard to the dayes of the Moones age , noted upon the uppermost part , as in the former , and therefore this must needes be a surer way than the former , for that depending upon the houre or indeed the houre and minute of the Moones change ( in which the Almanackes doe so much differ ) must needes cause an errour in the observation of the time : and neither this way nor the former , can be performed upon any Plane besides the Equinoctiall , by rea●on of the inequality of angles in all other Planes , whose houre-lines make angles of intersection .

And now in the conclusion of this worke , thus much I say ; that if the best inventions and conceits of men be haunted by some Momaicall Spirit at one time or other , as it is certaine they alwayes have beene and still are : Then sure I am , and I must not otherwise expect but that this of mine ( being so meane in comparison of many that have beene so haunted ) will be in the same case ; yet I may care the lesse , because the best of all have beene subject to Momus his censures : But whosoever hee be , that shall carpe hereat , or evilly censure it ; if he can finde out any other more exact way for this kinde of Horologiographie than that which I have conceited and here delivered ( it having not beene done before by any , for ought that I doe know or could ever heare ) as I doubt he cannot for the reasons formerly alleadged ; my request to him is , that he would be pleased to bestow a little paines in bringing of the same into light , and then I desire , that for ever after , this may ( as deservedly it might ) lye hidden in oblivion and dakenesse : In the meane season I commit these my poore endeavours to the courteous and favourable acceptation of the friendly Reader and practitioner , saying to him , ( concerning this matter ) somewhat in effect as I sayd before ,
