every four years, and made it the year of the _Romans_.

_Syncellus_ tells us, that the five days were added to the old year by the
last King of the Shepherds: and the difference in time between the Reign of
this King, and that of _Ammon_, is but small; for the Reign of the
Shepherds ended but one Generation, or two, before _Ammon_ began to add
those days. But the Shepherds minded not Arts and Sciences.

The first month of the Luni-solar year, by reason of the Intercalary month,
began sometimes a week or a fortnight before the Equinox or Solstice, and
sometimes as much after it. And this year gave occasion to the first
Astronomers, who formed the _Asterisms_, to place the Equinoxes and
Solstices in the middles of the Constellations of _Aries_, _Cancer_,
_Chelæ_, and _Capricorn_. _Achilles Tatius_ [69] tells us, that _some
antiently placed the Solstice in the beginning of _Cancer_, others 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_, _Chelæ_, 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,
