The Second Part of COSMOGRAPHY, VIZ. GEOGRAPHY.
GEOGRAPHY, is an Art that teacheth to make a true description of the Super∣ficies of the whole Earth. It is divided into General and Particular.
The General comprehends not only the whole Earth, as far as is discovered that is habitable, but also that part that lies under the Water. Now the description of the Waters belongs to Hydrography, of which more anon.
The Particular description of the Earth, ex∣tends [ 20] only to some Particular parts thereof, and is divided into Chorography, and Topography; so that as Cosmography is a description of the whole World, and Geography of the Earth; so is Cho∣rography a description of every Particular Countrey, or part of the Earth, such as is described by par∣ticular Maps, as of England, France, Spain, and the like. And whereas Topography is a descrip∣tion of every particular place, as Cities, Towns, Forests, Desarts, Woods, Mountains, Valleys, Lakes, [ 30] Marshes, Gulphs, Bays, Rivers, Streights, Havens, &c. the knowledg thereof cannot but be of great use, and delight to all men, especially to Travel∣lers.
Of the Motion of the Earth.
IN the Copernican Hypothesis, neither the Sun, nor Firmament have any Motion, but the [ 40] Sun is said to be so disposed in the middle, that the Globe of the Earth, together with the Sphaere of the Moon is continually carried about it, with a most rapid Motion; according to this Figure.
The Arguments, and Answers pro, and con, are many on both sides; but the most unanswer∣able proofs of the truth of the Ptolomaean, or [ 60] common received Hypothesis are these.
First, If our Terrestrial Globe were not placed in the midst or Center of the World, it would not be plainly made out, how the mid part of Heaven should be conspicuous to us, or how in the New Moon, the Sun and the Moon could be seen both at the same time in parts Diametrically opposite. And whereas they answer, That the Earth is but a small Punctum or Point in respect to the Heavens, and that therefore all this night well enough be without any contradiction to their Hypothesis, a greater Absurdity would still fol∣low, that is, that all the part of Heaven beneath the Horizon, would be equally seen by us with those parts above. Moreover, if the Earth were not placed in the middle of the World, there could not be a perpetual Aequinoctial in the Sphaera recta, in regard all the Circulations of the Sun, would be unequally cut by the Horizon. Also if the Earth were not in the middle of the World, there would not always be an Eclipse of the Moon, when she is Diametrically opposite to the Sun, since it would often happen that the Globe of the Earth, would not be exactly in the mid∣dle, and equally opposite to both those Planets, within the Line drawn from the Sun, through the middle part of the World to the Moon; whereas in Lunar Eclipses are never known, but when the Moon keeps her opposition with the Sun, through the middle of the World; the Moon then being exactly in the middle, as Astrono∣mers have always observed.
Next, there is this Pyhsical reason to be given, why the Earth is in the Center, namely, because all heavy things have their tendency thither, and consequently the Earth, as being of that Gravity which renders it unfit for Motion, and inclines it to a settlement in the lowest place, or Center.
Lastly, in the Copernican Hypothesis, the Globe of the Earth, is affirmed to be moved, not only about the Center of the World, but also about its own Axis; so as successively to receive the diurnal Light according to its different parts; but to refute this Assertion, hereafter it shall be made appear, that the Earth is a Magnetick-Bo∣dy, and consequently uncapeable of being moved about its own Axis, and this is the opinion of Galtruchij. But a larger Dicourse of this subject, which recites the Opinions of the Pythagoreans, Ptolomains, and Copernicans, you will find in the fifth Chapter of Varenius his Geography.
