the daughter of _Alcinous_, King of the _Pheaces_ in that Island: and it's most probable that she had it from the _Argonauts_, who [76] in their return home sailed to that Island, and made some stay there with her father. So then in the time of the _Argonautic_ Expedition, the Cardinal points of the Equinoxes and Solstices were in the middles of the Constellations of _Aries_, _Cancer_, _Chelae_, and _Capricorn_. In the end of the year of our Lord 1689 the Star called _Prima Arietis_ was in [Aries]. 28 deg.. 51'. 00", with North Latitude 7 deg.. 8'. 58". And the Star called _ultima caudae Arietis_ was in [Taurus]. 19 deg.. 3'. 42", with North Latitude 2 deg.. 34'. 5". And the _Colurus AEquinoctiorum_ passing through the point in the middle between those two Stars did then cut the Ecliptic in [Taurus]. 6 deg.. 44': and by this reckoning the Equinox in the end of the year 1689 was gone back 36 deg.. 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 deg.. 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 Caudae_: 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 661/2 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 [nu] by _Bayer_: in the end of the year 1689, and beginning of the year 1690, its Lo
