131. To an observer at either Pole, the Horizon and Equinoctial are
coincident; and the Sun and Stars seem to move parallel to the Horizon:
therefore, such an observer is said to have a Parallel position of the
Sphere. To an observer any where between the Poles and Equator, the
Parallels described by the Sun and Stars are cut obliquely by the
Horizon, and therefore he is said to have an Oblique position of the
Sphere. To an observer any where on the Equator, the Parallels of
Motion, described by the Sun and Stars are cut perpendicularly, or at
Right angles, by the Horizon; and therefore he is said to have a Right
position of the Sphere. And these three are all the different ways that
the Sphere can be posited to all people, on the Earth.
