In the end of the year of our Lord 1689 the Star called _Prima Arietis_ was
in [Aries]. 28°. 51'. 00", with North Latitude 7°. 8'. 58". And the Star
called _ultima caudæ Arietis_ was in [Taurus]. 19°. 3'. 42", with North
Latitude 2°. 34'. 5". And the _Colurus Æquinoctiorum_ passing through the
point in the middle between those two Stars did then cut the Ecliptic in
[Taurus]. 6°. 44': and by this reckoning the Equinox in the end of the year
1689 was gone back 36°. 44'. since the _Argonautic_ Expedition: Supposing
that the said _Colure_ passed through the middle of the Constellation of
_Aries_, according to the delineation of the Ancients. The Equinox goes
back fifty seconds in one year, and one degree in seventy and two years,
and by consequence 36°. 44'. in 2645 years, which counted back from the end
of the year of our Lord 1689, or beginning of the year 1690, will place the
_Argonautic_ Expedition about 25 years after the Death of _Solomon_: but it
is not necessary that the middle of the Constellation of _Aries_ should be
exactly in the middle between the two Stars called _prima Arietis_ and
_ultima Caudæ_: and it may be better to fix the Cardinal points by the
Stars, through which the _Colures_ passed in the primitive Sphere,
according to the description of _Eudoxus_ above recited. By the _Colure_ of
the Equinoxes, I mean a great Circle passing through the Poles of the
Equator, and cutting the Ecliptic in the Equinoxes in an Angle of 66½
degrees, the complement of the Sun's greatest Declination; and by the
_Colure_ of the Solstices I mean a great Circle passing through the same
Poles, and cutting the Ecliptic at right Angles in the Solstices: and by
the Primitive Sphere, that which was in use before the motions of the
Equinoxes and Solstices were known: now the _Colures_ passed through the
following Stars according to _Eudoxus_.

In the back of _Aries_ is a Star of the sixth magnitude, marked ν by
_Bayer_: in the end of the year 1689, and beginning of the year 1690, its
