A19937	The seamans secrets deuided into 2. partes, wherein is taught the three kindes of sayling, horizontall, peradoxall [sic], and sayling vpon a great circle : also an horizontall tyde table for the easie finding of the ebbing and flowing of the tydes, with a regiment newly calculated for the finding of the declination of the sunne, and many other most necessary rules and instruments, not heeretofore set foorth by any / newly published by Iohn Dauis of Sandrudge ...

The Poles altitude is the distance betweene the Pole and the Horizon or that portion of the Meridian which is contained betweene the Pole and the Horizon The altitude of the Sunne aboue the Horizon is that portion of the circle of Azumuth which is contained betweene the Horizon and the Sunne Latitude is that arke of the meridian which is contained betweene the parallell of any place and the Equator or that part of the Meridian which is included betweene the Zenith and the Equinoctiall Longitude is that portion of the Equator contained betweene the Meridian of S. Mihels one of the Iles of the Assones and the Meridian of the place whose longitude is desired the reason why the accompt of longitude doth begin at this I le is because that there the Compasse hath no varietie for the Meridian of this I le passeth by the Poles of the worlde and the Poles of the Magnet being a Meridian proper to both Poles The longitude betweene place and place is the portion of the Equator which is contained betweene the Meridians of the same places Declination is the distance of the Sunne Moone and Starres from the Equinoctiall or that portion of the Meridian which passeth by the Center of any celestiall body and is contained betweene the same center and the Equinoctiall Hidrographie is the description of the occean Sea with all Iles bancks rocks and sands therein contained whose limits extend to the geographicall borders of the earth the perfect notice whereof is the cheefest thing required in a sufficient Pylote in his excellent practise of sayling Geographie is the description of the earth onely whereby the terrestriall forme in his due situation is giuen whose distinction is by mountaines riuers vallies cities and places of fame without regarde of the Circles Clymates or Zones Cosmographie is the description of the heauens with all that is contained within the circute thereof but to the purpose of nauigation we must vnderstand Cosmographie to be the vniuersall description of the terrestriall Globe distinguished by all such circles by which the distinction of the celestiall Sphere is vnderstoode to be giuen with euery Countrie Coast Sea Harborow or other place seated in their true longitude latitude Zone and Clyme The Chart is a speciall instrument in Nauigation pretending the Cosmographicall description of the terrestriall Globe by all such lynes circles corses and diuisions as are required to the most exquisite skill of nauigation The end of the First Booke THE SECOND PART OF THIS TREATISE OF NAVIGATION WHERIN IS TAVGHT THE nature and most necessary vse of the Globe with the Circles Zones Climates and other distinctions to the perfect vse of Sayling By which most excellent Instrument is perfourmed all that is needfully required to the full perfection of all the three kindes of Nauigation THE SECOND BOOKE OF THE SEAMANS SECRETS What is the Sphere THe Sphere is a solide body contained vnder one superficies in the midst whereof there is a point or prick which is the Center of the Sphere from whence all right lines drawn to the circumference are equall the one to the other whereby it is to be vnderstoode that the centre of the Sphere is so euenly placed in his midst as that it hath like distance from all parts of the Circumference And forasmuch as the Sphere is an instrument demonstrating nnto us the nniuersall ingine of the world we must therfore vnderstand this Center to be this terrestrial Globe wherin we haue our being which compared to the celestial Globe or heauenly circumference doth beare propertie as the center to his circle which earthly globe by the diuine mightie workmanship of God doth admirably hang vpon his center being of equall distance from all partes of the circumference What are the distinctions of the Sphere THe Sphere is distinguished by ten circles whereof sixe are great circles and 4. are lesser circles whereof there are onely 8. described vpon the body of the Globe limiting the Zones and motion of the Planets as the Equinoctiall the Ecliptick the Equinoctiall Colure the Solsiticial Colure the Tropick of Cancer the Tropick of Capricorne the Artick Polar Circle and the Antartick Polar Circle The Horizon and Meridian are not described vpon the body of the Globe but artificially annexed thereunto for the better perfection of his vse Which are the great circles and which the lesser THe Equator the Ecliptick the 2. Colures the Meridian and the Horizon are great circles because they deuide the sphere into 2. equall parts The 2. Tropicks the 2. Polar circles are lesser circles because they deuide the Sphere into 2. vnequall partes What is the Equator or Equinoctiall THe Equinoctial is a great circle deuiding the Sphere into 2. equal parts leauing the one halfe towardes the North and the other halfe towards the South and is equally distant from both the Poles of the worlde 90. degrees placed euenly betweene them and described vpon them this line crosseth the Horizon in the true points of East and West and hath alwaies his owne halfe aboue the Horizon vnles it be vnder either of the Poles for there the Equator is in the Horizon it crosseth the Meridian at right Spherick angles and it also crosseth the Ecliptick line in the first minute of Aries and Libra diuiding the Ecliptick and Horizon and is also by them deuided into two equall partes This line is also deuided into 360. equall partes or degrees which are the degrees of Longitude beginning the account in the point of Aries reckoning twoards the East concluding the number 360. in the place where the first account began viz where the Equator doth intersecte the Ecliptick in the first minute of Aries vnder which Meridian S. Mihels one of the yles of the assores is to be placed in the geographicall description of the terrestriall Globe What is the vse of the Equator THe vse of the Equinoctiall is to know the declination of the Sunne Moone Starres wherby the latitude of places is giuen for that portion of the Meridian which is contained betweene the Equator and the Centre of the Sunne Moone or Starres is their declination also by the Equinoctiall is knowne the Longitude of places for a quarter of a great Circle being drawne from the Pole to the place whose Longitude is desired and so continued to the Equinoctiall that degree and minute in which the quarter circle dooth touch the Equator is the Longitude of the same place or if you bring any place that is described vpon the Globe whose Longitude you would know vnder the Meridian of the Globe that degree of the Equinoctiall that is then likewise directly vnder the Meridian is the Longitude desired When the sunne commeth vpon the Equator then the Daies and nights are of one length through the whole worlde and then the Sunne riseth vpon the true point of East and setteth vpon the true point of West and not els at any time This circle being fixed in the
