A85532 The Antiquity & excellency of globes. What a globe is, and of the circles without the globe, what the horizon is with the things described thereon, also what the meridian is, the poles, axes, houre circle and index. Moreover of the circles which are described on the supersicies of the globes; of the equinoctiall circle, zodiack, and eccliptick, of the tropicks, what the artick and antartick circles are; of the verticall circles, and quadrant of latitude, of the zones and their numbers of climates and paralels. All which are proper to the celestiall and terrestriall globes, with their uses, profitable for all that would be instructed in geography. 1653 (1653) Wing G1524; Thomason E689_27; ESTC R206953 18,791 33

the Northerne and Southern Hemisphears together with the Zodiack containeth in all 1022 stars which make up 48 Asterismes or constellations How to make a Sun Dyall by the Globe for any latitude of place FOr the making of a plaine Horizontall dyall having first prepared your flat dyall ground parallel to the Horizon draw a Meridian on it as exactly North and South as possibly you can which done draw another East and West which must crosse it at right Angels The first of which lines will shew 12 and the other 6 of the Clock both morning and evening Then making a Center in the interfection of these two lines describe a Circle on your dyall to what distance you please and then divide it as all othr Circles usually are into 360 parts and it will not be amisse to sub-devide each of these into lesser parts if it may be conveniently done And now it only remaines to finde out the distances of the houre lines in this Circle for any latitude of place which that we may doe by the use of the Globe let it first be set to the Latitude of the place assigned and then make choice of some of the greater Circles in the Globe that passe through the Poles of the world As for example The Aequinoctiall colour if you please and apply the same to the Meridian in which scituation it sheweth the mid-day or 12 a Clock then turning about the Globe toward the West if you will till that 15 degrees of the Aequator have passed through the Meridian you must marke the degree of the Horizon that the same colour crosseth in the Horizon for that point will shew the distance of the first and 11th houres from the Meridian both of which are distant an hours space from the Meridian or line of Mid-day then turning againe the Globe forward till other fifteen degrees are past the Meridian the same colour will point out the distance of the 10th hour which is 2 hours before noon and of the second hour after-noon and in the same manner may you finde out the distances of all the rest in the Horizon allotting to each of them 15 degrees in the Aequator crossing the Meridian but here you must take notice by the way that the beginning of this account of the distances must be taken from that part of the Horizon on which the Pole is elevated to wit from the North-part of the Horizon if the Artick Pole be elevate and so likewise from the South part if the Antartick be elevated The distances of the hours being thus noted in the Horizon of the Globe you must afterward translate them into your plaine allotted for your dyal ground reckoning in the circumference of it so many degrees to each houre as are answerable to those pointed out by the colour in the Horizon and lastly having thus done the Gnomon or Stile must be erected where you are to observe this one thing which is indeed the chief thing to be carefully looked unto namely that that edge or line of the Gnomon which is to shew the hours by its shadow in all kinds of dyals must be set paralel to the Axis of the world that so it may make an angle of inclination with its plaine ground equall to that which the Axis of the world makes with the Horizon now that the stile is to stand directly to the North and South or the Meridian line is a thing commonly knowne Now if you would make a plaine erect dyal perpendicular to the Horizon which is commonly called a Mural and respecting either the North or South you must remember this one thing that that which is an erect dyall in one place will be a Horizontall in another whose Zenith is distant from that place 90 degrees either North-ward or South-ward And so likewise by this rule may be made any manner of inclining dyall if so be that the quantity of the inclination be but knowne as for example if a dyall be made on a plain ground whose inclination is ten degrees from the Horizon Southward and for a place whose latitude is 52 gr North-ward you must describe it in that plaine and horizontall dial for the Latitude of 62 degrees North-ward and if in the same Latitude the diall ground doe incline toward the North 16 gr you must take in horizontall dial for the Northerne latitude of 36 gr And thus much for making dials by the Globe FINIS A Figure of the Spheare AMERICA was first discoverd the yeer 1492 by Christopher Columbus at the charge of Ferdinand Isabella K and Q of Castill but denominated of Ameri●cus Vesputius seven yeers after To the Right Hon ble Henry Mountague Baron of Kimbolton Viscount Maundevile Lo President of his Ma ties most Ho ble Privy Counsell this Mapp of the World with Himselfe and his best services Will Grent This South Land undiscouered commonly knowne by the name of Terra Australis incognita Magellanica cannot certainly be affirmed either continent or Ilands only some few coasts thereof haue appeared to Seamen Driuen thervpon by extremity of weather whose names are set downe the rest must remaine clouded in obscuritie till future times and further discoueries produce them to light
