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, Chelæ, and Capricorn.
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.
