THE PREFACE.

Sesostris, one of the kings of Egypt, who, going about to

make a passage out of the Mediterranean into the Arabian

Gulfe, is said to have desisted from his purpose because he

found that the superficies of the Arabian Gulfe was higher

Aristotle, than was the Mediterranean, as it is reported by Aristotle in

the end of his first booke of Meteors. The like is also said

in the same place by the same Authour to have happened

afterward to Darius. Now whether the Architects or

Water-levellers employed by Demetrius, Sesostris, and

Darius deserve more credit than those whom Patricius

nameth I shall not much trouble my selfe to examine. Yet

Strabo inveigheth against Eratosthenes for attributing any

such eminences and depressions to the superficies of the Sea.

And Archimedes his doctrine is that every humid body

standing still and without disturbance hath a sphrerieall

superficies whose centre is the same with that of the Earth.

So that wee have just cause to regret the opinions, both of

those that contend that the superficies of the Sea is plaine,

as also of those that will have it to be in some places higher

than in other. Although wee cannot in reason but confesse that

so small a portion of the whole Terrestriall Globe as may be

comprehended within the reach of our sight, cannot be dis-

tinguished by the helpe of any Instruments from a plaine

superficies. So that we may conclude Patricius his argument,

which he alleadgeth from the experience of Water-con-

veighers, to be of no weight at all.

But hee goes on and labours to prove his assertion from

the elevation and depression, rising and setting of the Poles

and Starres, which were observed daily by those that traverse

the Seas ; all which he saith may come to passe, although the

surface of the water were plaine. For if any Starre be

observed that is in the verticall point of any place,

which way soever you travell from that place, the same

Starre will seeme to be depressed, and abate something of

its elevation, though it were on a plaine superficies. But

there is something more in it than Patricks takes notice of.

For if wee goe an equall measure of miles, either toward the

North or toward the South, the elevation or depression of

the Starre will always bee found to be eqnall: which that

it can possibly bee so in a plaine superficies is more than

bee will ever be able to demonstrate. If wee take any

Starre situate neare the ^Equator, the same, when you have

removed thence 60 English miles, will be elevated about a

degree higher above the Horizon, whether the Starre be

directly over your head, or whether you depart thence that

so it may bee depressed from your Zenith for 30 or 50 or

any other number of degrees. Which that it cannot thus

be on a plaine superficies may bee demonstrated out of the

principles of Geometry. But yet methinks this one thing

might have persuaded Patricius (being so well versed in the

Histories of the Spanish Navigations, as his writings suffi-

ciently testifie) that the superficies of the Sea is not plaine,

because that the Ship called the Victory, wherein Ferdinand

Magellane, losing from Spaiue and directing his course to-

ward the South-west parts, passed through the Straits,

called since by his name, and so touching upon the Cape of

Good Hope, having encompassed the whole world about,

returned again into Spaine. And here I shall not need to

mention the famous voyages of our owne countriemen, Sir

Francis Drake and Master Thomas Candish, not so well

knowne perhaps abroad, which yet convince Patricius of the

same errour. And thus have we lightly touched the chiefe

foundations that his cause is built upon ; but as for those ill-

understood experiments which he brings for the confirmation

of the same, I shall let them passe, for that they seeme

rather to subvert his opinion than confirme it.

Thus, having proved the Globe of the Earth to be of a

Sphericall figure, seeing that the emineney of the highest

hills hath scarcely the same proportion to the semidiameter

of the Earth that there is betwixt 1 and 1,000, which how

THE PREFACE.

small it is an)' one may easily perceive; I hold it very

superfluous to goe about to prove that a Globe is of a figure

most proper and apt to expresse the fashion of the Heavens

and Earth as being most agreeable to nature, easiest to be

understood, and also very beautifull to behold.

Now in Materiall Globes, besides the true and exact

description of places, which is, indeed, the chiefest matter

to be considered, there are two things especially recpnred.

The first whereof is the magnitude and capacity of them,

that so there may be convenient space for the description of

each particular place or region. The second is the light t-

nesse of them, that so their weight be not cumbersome.

Strabo, in his eleventh booke, would have a Globe to have

tenne foot in Diameter, that so it might in some reasonable

manner admit the description of particular places. But this

bulke is too vast to bee conveniently dealt withall. And in this

regard I think that these Globes, of which I intend to speak

in this ensuing discourse, may justly bee preferred before all

other that have been set before them, as beinge more capa-

cious than any other ; for they are in Diameter two foot and

two inches, whereas Mercator's Globes (which are bigger than

any other ever set before him) are scarcely sixteene inches

Diameter. The proportion therefore of the superficies of

these Globes to Mercator's will be as 1 to 2|, and somewhat

more. Every country, therefore, in these Globes will be

above twice as large as it is in Mercator's, so that each par-

ticular place may the more easily bee described. And this

I would have to bee understood of those great Globes made

by William Saunderson of London ; concerning the use of

which especially we have written this discourse. For he

hath set forth other smaller Globes, also, which as they are

of a lesser bulke and magnitude, so are they of a cheaper

price, that so the meaner Students might herein also be

provided for. Now concerning the geographicall part of

them, seeing that it is taken out of the newest Charts and

descriptions ; I am bold to think them more perfect than

any other : however they want not their errours. And I

thinke it may bee the authors glory to have performed thus

much in the edition of these Globes. One thing by the

way you are to take notice of, which is that the descrip-

tions of particular places are to be sought for elsewhere,

for this is not to be expected in a Globe. And for these

descriptions of particular countries, you may have recourse

to the Geographicall Tables of Abrahamus Ortelius,1 whose

diligence and industry in this regard seemes to exceed all

other before him. To him, therefore, we referre you.2

1 In the edition of 1659 the name of Gerardus Mercator is substi-

tuted for that of Abrahamus Ortelius.

2 In the Dutch editions here follows a long note by Pontanus,

describing the globe of Tycho Brahe at Prague, and those of the

Duke of Tuscany ; and giving the definitions of Euclid.

THE FIRST PART.

Of those things which are common both to the

Ccelestiall and Terrestrial! Globe.

CHAPTER I.

What a Globe is, vjith the 2>arts thereof, and of the Circles of

the Globe.

A GLOBE, in relation to our present purpose, we define to be

an Analogicall representation either of the Heavens or the

Earth. And we call it Analogicall, not only in regard of its

forme expressing the Sphrericall figure as well of the

Heavens, as also of the Terrestriall Globe, consisting of the

Earth itselfe, together with the interflowing Seas ; but rather

because that it representeth unto us in a just proportion and

distance each particular constellation in the Heavens, and

every severall region and tract of ground in the Earth ;

together with certaine circles, both greater and lesser, in-

vented by Artificers for the more ready computation of the

same. The greater Circles we call those which divide the

whole superficies of the Globe into two equall parts or halves ;

and those the lesser which divide the same into two tmequall

parts.1

Besides the body of the Globe itselfe, and those things

which we have said to be thereon inscribed, there is also

annexed a certain frame with necessary instruments thereto

belonging, which we shall declare in order.

1 Here Pontanus inserts another long note, in the Dutch edition,

respecting a discussion between Tycho Braye and Peter Ramus, on

the method of astronomical computation in use among the ancient

Egyptians.

A TREATISE OF THE

The fabricke of the frame is thus: First of all there is a

Base, or foot to rest upon, on which there are raised perpen-

dicularly sixe Columnes or Pillars of equal 1 length and dis-

tance ; upon the top of which there is fastened to a levcll

and parallel to the Base a round plate or circle of wood, of a

sufficient breadth and thicknesse, which they call the Hori-

zon, because that the uppermost superficies thereof performeth

the office of the true Horizon. For it is so placed that it

divideth the whole Globe into two equall parts, Whereof

that which is uppermost represented unto us the visible

Hemisphere, and the other that which is hid from us. So
