AN Introduction TO GEOGRAPHY.
GEOGRAPHY is a Science which Teacheth the Description and Dimension of all the Earth, as it doth together with the Water, compose that round Body, which from its form is called the Orb or Globe of the Earth; Describing the Scituations, and Measuring the Distances of all its parts.
The Earth is placed in respect of the other Orbs or Stars of the Uni∣verse, according to Ptolomy and Tycho, in the Centre; but according to Copernicus, between the Orbs of Mars and Venus.
The Globe of the Earth is variously Described by Geographers into Lines and Parts, which are either Real or Imaginary.
Real, are such as agree to the Terrestrial Globe, by Nature. Imaginary, are such as agree to it by vertue of our understanding.
The Real parts of the Terrestrial Globe are Earth and Water. The Imaginary parts are certain Lines, which are not materially, but for the better understanding of this Science, are supposed to be on the Earth.
These Lines are either Strait, or Circular. The Axis is a strait line passing through the midst or Center of the Earth, which is the Diameter of the whole World: the extream points or ends whereof, are called the Poles, upon which the Universe is supposed to move; the one Point is called the Artick, or North-Pole, the other the Antartick, or South-Pole.
The Circular Lines are divided into the greater and the lesser: The greater Circles are such as divide the Globe into two equal parts, and are
