thers in the
eighth degree of _Cancer_, others about the twelfth degree, and others
about the fifteenth degree thereof._ This variety of opinions proceeded
from the precession of the Equinox, then not known to the _Greeks_. When
the Sphere was first formed, the Solstice was in the fifteenth degree or
middle of the Constellation of _Cancer_: then it came into the twelfth,
eighth, fourth, and first degree successively. _Eudoxus_, who flourished
about sixty years after _Meton_, and an hundred years before _Aratus_, in
describing the Sphere of the Ancients, placed the Solstices and Equinoxes
in the middles of the Constellations of _Aries_, _Cancer_, _Chelae_, and
_Capricorn_, as is affirmed by [70] _Hipparchus Bithynus_; and appears also
by the Description of the Equinoctial and Tropical Circles in _Aratus_,
[71] who copied after _Eudoxus_; and by the positions of the _Colures_ of
the Equinoxes and Solstices, which in the Sphere of _Eudoxus_, described by
_Hipparchus_, went through the middles of those Constellations. For
_Hipparchus_ tells us, that _Eudoxus_ drew the _Colure_ of the Solstices,
through the middle of the _great Bear_, and the middle of _Cancer_, and the
neck of _Hydrus_, and the Star between the Poop and Mast of _Argo_, and the
Tayl of the _South Fish_, and through the middle of _Capricorn_, and of
_Sagitta_, and through the neck and right wing of the _Swan_, and the left
hand of _Cepheus_; and that he drew the Equinoctial _Colure_, through the
left hand of _Arctophylax_, and along the middle of his Body, and cross the
middle of _Chelae_, and through the right hand and fore-knee of the
_Centaur_, and through the flexure of _Eridanus_ and head of _Cetus_, and
the back of _Aries_ a-cross, and through the head and right hand of
_Perseus_.

Now _Chiron_ delineated [Greek: schemata olympou] the _Asterisms_, as the
ancient Author of _Gigantomachia_, cited by [72] _Clemens Alexandrinus_
informs us: for _Chiron_ was a practical Astronomer, as may be there
understood also of his daughter _Hippo_: and _Musaeus_, the son of
_Eumolpus_ and master of _Orpheus_, and one of the _Argonauts_, [73] made a
Sphere, and is reputed the first among the _Greeks_ who made one: and the
Sphere it self shews that it was delineated in the time of the _Argonautic_
expedition; for that expedition is delineated in the _Asterisms_, together
with several other ancienter Histories of the _Greeks_, and without any
thing later. There's the golde
