A15751 The description and vse of the sphaere· Deuided into three principall parts. Whereof the first intreateth especially of the circles of the vppermost moueable sphære, and of the manifold vses of euery one of them seuerally. The second sheweth the plentifull vse of the vppermost sphære, and of the circles thereof joyntly. The third contayneth the description of the orbes whereof the sphæres of the sunne and moone haue been supposed to bee made, with their motions and vses. By Edvvard Wright. The contents of each part are more particularly set downe in the table. Wright, Edward, 1558?-1615. 1627 (1627) STC 26022; ESTC S120334 50,441 102

much are the poles of the Ecliptick distant from the Poles of the world CHAP. XVI Vses of the Polar Circles 1. THe Polar Circles shew the poles of the Zodiack and shew their distance from the poles of the Equinoctiall 2. The temperate Zones are bounded by these polar circles for the Articke circle boundeth the North side of the North temperate Zone and the Antartick circle boundeth out the South side of the South temperate Zone 3. The Polar circles separate the temperate Zones from the cold Zones which they compasse round about and inclose within them Therefore the foure lesser circles that is the two Polar circles and the Tropicks deuide Heauen and Earth into fiue Zones CHAP. XVII Of the Zones A Zone is a space of Heauen or Earth conteyned betweene two of the smaller Circles or inclosed within the compasse of either Polar circle They are called Zones that is as much to say as girdles because they compasse about Heauen or Earth like a girdle The Zones are deuided by auncient Writers into two kindes that is into temperate and vntemperate Zones A temperate Zone is the space of Heauen or earth conteyned betweene either of the Tropicks and the next Polar circle There be two temperate Zones the one North the other South The North temperate Zone is conteyned betweene the Tropicke of Cancer and the Artick polar circle The South temperate Zone is that which is conteyned betweene the Tropicke of Capricorne and the Antartick polar circle They are called temperate Zones because they haue a better temperature of the ayre for the most part and more meer for habitation then the vntemperate Zones The bredth of eyther temperate Zone is alwayes equall to the complement of the distance of the Tropicks and therefore in this age is about 43. degrees that is 2580. English miles There be two kinde of vntemperate Zones the one exceeding in heat the other in cold for the most part The hot vntemperate Zone called also the Torrid that is the burnt or broyled zone is that space of Heauen or Earth which is conteyned betweene the tropicks It is called the burnt Zone because that by reason of the Sunnes continuall going ouer that zone and casting his beames directly downe thereupon it is scorched with ouer-much heat and is not so meet to be inhabited as the temperate zones The bredth of this Zone is alwayes equall to the obliquitie of the Zodiack or greatest declination of the Sunne doubled which in our time is about 47. degrees that is 2820. English miles The cold or frozen zones are the spaces of Heauen or earth conteyned within the Polar circles There be two cold zones the one North conteyned within the compasse of the Articke circle the other South conteyned within the compasse of the Antartick Polar circle These zones exceed in cold because they want the sight of the sunne for a great part of the yeare and when the Sunne appeareth vnto them his beames fall so obliquely vpon them that they can in all likelyhood receiue but small heat thereby for the most part The bredth of these Zones is measured from the Poles of the world to the Polar circles and therefore must alwayes bee so much as the Polar circles are distant from the Poles that is in our age about 23. Degrees and a halfe which make 1410. English miles CHAP. XVIII The difference of Shadowes that the Sunne maketh in these Zones THey that dwell in the torride Zone doe cast their shadowes which the Sunne maketh at noone which we may therefore call their noone shadowes both towards the North and towards the South towards the North when the sunne is betwixt their zenith and the south point of the Horizon and towards the South where the sunne is betweene their Zenith and the North. For seeing the zenith of them that dwell in that Zone is betweene the Tropicks the sunne must needs bee sometimes Northwards from their zenith and so make a south shadow and sometime Southwards and then make a north shadow For which cause they that inhabite this Zone are called Amphiscij that is such as cast their noone shadowes on both sides But they that dwell in the temperate Zones are called Heteroscij that is such as cast their shadowes at noone one way onely For they that dwell in the North temperate Zone haue the Sunne alwayes at noone from their Zenith Southwards and therefore must needs alwayes cast their noone shadowes Northwards Whereas contrariwise they that inhabit the South temperate Zone hauing the Sunne at noone alwayes Northwards from their Zenith must needs haue their shadowes at noone alwayes towards the South And they that are in the cold Zones are called Periscij that is such as cast their shadowes round about them For seeing the Sunne continueth euery yeare for certaine dayes together alwayes aboue their Horizon and therefore moueth round about them without setting it must needs bee that their shadowes also are carried round about them falling towards all parts of the world in the space of 24. houres * ⁎ * THE SECOND PART Of the vses of the vppermost SPHAERE and of the Circles thereof joyntly PROP. I. To rectifie the Sphaere to the Latitude c. FIrst finde by obseruation or otherwise the height of the Pole or Latitude of that place for which you would rectifie the Sphaere Then by turning about the Meridian of the Sphaere lift vp or put downe the North Pole of the Sphaere about which the houre circle is fastened till the arch of the Meridian from the North part of the Horizon vpwards vnto the Pole be iust so many degrees as the eleuation of the Pole or latitude of the place was found to be for so haue you the Sphaere duly rectified As for example the Latitude of the Citie of London is 51. degrees and 32. minutes therefore if you lift vp the North Pole of the Sphaere aboue the North part of the Horizon so many degrees and minutes you shall haue your Sphaere rectified for that place PROP. II. To know the place of the Sunne c. LOoke the day of the moneth for which you desire to know the place of the Sunne in the Horizon and see what signe and degree of the Zodiacke vpon the Horizon answereth thereto for there haue you the place of the Sunne Take for example the 25. of December looke this day therefore in the Horizon and you shall finde answerable thereto 13. degrees and about 40. minutes of Capricorne which is the place of the Sunne at that time PROP. III. To know the declination of the Sunne c. BRing the point whose declination you desire to know vnto the Meridian of the Sphaere and look what number of degrees and minutes of the Meridian is conteyned betweene that point and the Equinoctiall for so much is the declination As if you would know the declination of the 10. degree of Taurus bring that degree to the Meridian and you shall finde the arch of the Meridian between
points the difference of the Sunnes returning is for certaine dayes insensible Hereof the Sunne is said to make his station or to stand when he commeth to either of those points They that dwell without the Tropickes haue two sunne-standings that is the Summer sun-standing or high sun-standing when the Sunne in Summer time is at the highest and next vnto our Zenith being in the beginning of Cancer and the winterly or low sun-standing when the Sunne in Winter time is lowest in the Meridian and furthest from our Zenith But they that dwell within the Tropicks by a certaine similitude taken from our sun-standings wherein the Sunne is either highest or lowest are said to haue foure sun-standings that is two high sun-standings when the Sunne passeth by their Zenith the highest point in the Heauens which hapneth twice euery yeare in two places equally distant from the beginnings of Cancer and Capricorne and two low sun-standings when the Sunne is in the beginning of Cancer and Capricorne 2. In this Circle by the arch conteyned betweene the Equator and Eclipticke we measure the greatest declination of the Sunne or obliquity of the Eclipticke which in Ptolomees time was 23. degrees 51. minutes and one third part of a minute But euer since that time it hath beene found by obseruation to decrease so as in this our age it is no more then 23. degrees and one halfe or little more Notwithstanding Copernicus thought that the greatest obliquity was 23. degrees 28. minutes 3. It sheweth the places of the Eclipticke in which the Sunne comming neerest to our Zenith maketh the artificiall day longest or going furthest from the same point maketh the same shortest 4. It deuideth the Zodiacke into two halfes the one ascending and the other descending 5. Hereby also the signes are distinguished which doe rise rightly and which rise obliquely in an oblique Sphaere For the descending halfe riseth rightly and the ascending halfe riseth obliquely 6. So the points of the Eclipticke are shewed by this Circle wherein the greatest difference of right and oblique ascensions happeneth It distinguisheth those signes in which when the Sunne moueth the artificiall dayes are increased and the nights decrease from those signes wherein the dayes are diminished and the nights increase 7. In this circle are the bredths of the Zones bounded for the obliquity of the Eclipticke doubled sheweth the bredth of the torrid or burnt Zone the distance of the poles of the Ecliptick and of the Poles of the Equator shew the bredth of the cold or frozen Zones and the other two Arches remaining shew the bredths of the temperate Zones CHAP. XIII The Description of the two Tropickes THe two smaller Circles Equidistant in all places from the Equinoctiall and comming vnder these Solstitiall points of the Eclipticke on both sides are called the Tropicks that is circles of returne And they are so called because that when the Sun commeth to them it beginneth to returne backe againe towards the Equinoctiall circle Or else they may be so called because they are described by the turning about of the Tropicall points of Cancer and Capricorne They are also called solstitiall Circles that is Circles of the sun-standings because that by reason of the insensible alteration of the declination of the Ecliptick for some space both before and after the Tropicall points the Sunne in respect of his Meridian altitudes or in respect of the motion he hath towards the North or South by reason of the obliquity of the Eclipticke seemeth to stand as it were for certaine dayes in those places There be two Tropicks the Tropick of Cancer and the tropicke of Capricorne The tropick of Cancer toucheth the Ecliptick in the beginning of Cancer which is the most northerly point of the Ecliptick or it is the Tropick described in the first mouable Sphaere by the Summer solstitiall point This circle is called the Tropick of Cancer because it toucheth the Ecliptick in the beginning of Cancer It is also called the Summer Tropick and the Tropick of the Summer sun-standing because that when the Sunne commeth to it the Summer beginneth It is called the North tropick because it is in the North part of the world and the Circle of the high sunne-standing because the Sunne comming to it is highest in the Meridian and next vnto our Zenith which dwell in the North part of the world without the Tropicks The Tropick of Capricorne is the Tropick which toucheth the Ecliptick in the first point of Capricorne It is called the Tropick of Capricorne because it toucheth the Ecliptick in the beginning of Capricorne It is called the winter Tropicke and Tropick of the Winter sun-standing because the Sunne commeth to it in Winter It is also called the circle of the lowest Sunne-standing because that when the Sunne commeth to this Tropicke it is furthest distant from our Zenith and hath his lowest height in the Meridian CHAP. XIIII Vses of the Tropickes 1. THe Tropicks shew the Tropicall or Solstitiall points of the Eclipticke that is the points wherein the Sunne seemeth to stand and beginneth to returne backe againe 2. They bound out the greatest declinations of the Sunne which in our times is about 23. degrees and an halfe 3. Therefore they doe also bound out the obliquity of the Ecliptick for they are the bounds of the Sunnes way beyond which the Sunne goeth not at any time 4. The Sunne comming to either of these circles is either neerest or furthest distant from our verticall point 5. In an oblique Sphaere they measure out the shortest and longest artificiall day and night 6. The Tropicks aswell in Heauen as in Earth conteyne betwixt them the Torrid Zone and separate it from the temperate CHAP. XV. The Polar Circles THe two smallest circles that are next about the poles of the Sphaere are called the polar circles They are drawne by the poles of the Eclipticke and are euery where Equidistant from the Equinoctiall and from the poles of the Sphaere They are called polar Circles either because they are neere the poles of the Sphaere or else because they are described by the motion of the poles of the Eclipticke And therefore there be two polar Circles that is so many as there are poles of the Ecliptick the Polar circle Artick and the Polar Antartick The Articke polar circle is that which passeth by the North pole of the Ecliptick or which is described by the North pole of the Ecliptick being carried about with the motion of the first moueable Sphaere The Antartick polar circle is that which goeth by the South pole of the Eclipticke being described with the first motion by the Antartick pole of the Ecliptick The distance of these polar Circles from the poles of the Sphaere is equall to the distance of the tropicks from the Equinoctiall which in our time is about 23. degr and an halfe for so much as is the obliquity of the Zodiack whereto the distance of the Tropicks from the Equinoctiall is alwayes equall so
