By the same method the place of any Star in the Primitive Sphere may readily be found, counting backwards one Sign, 6°. 29'. from the Longitude which it had in the end of the year of our Lord 1689. So the Longitude of the first Star of _Aries_ in the end of the year 1689 was [Aries]. 28°. 51'. as above: count backward 1 Sign, 6°. 29'. and its Longitude, counted from the Equinox in the middle of the Constellation of _Aries_, in the time of the _Argonautic_ expedition, will be [Pisces]. 22°. 22': and by the same way of arguing, the Longitude of the _Lucida Pleiadum_ in the time of the _Argonautic_ Expedition will be [Aries]. 19°. 26'. 8": and the Longitude of _Arcturus_ [Virgo]. 13°. 24'. 52": and so of any other Stars. After the _Argonautic_ Expedition we hear no more of Astronomy 'till the days of _Thales_: He [77] revived Astronomy, and wrote a book of the Tropics and Equinoxes, and predicted Eclipses; and _Pliny_ [78] tells us, that he determined the _Occasus Matutinus_ of the _Pleiades_ to be upon the 25th day after the Autumnal Equinox: and thence [79] _Petavius_ computes the Longitude of the _Pleiades_ in [Aries]. 23°. 53': and by consequence the _Lucida Pleiadum_ had, since the _Argonautic_ Expedition, moved from the Equinox 4°. 26'. 52": and this motion, after the rate of 72 years to a Degree, answers to 320 years: count these years back from the time in which _Thales_ was a young man fit to apply himself to Astronomical Studies, that is from about the 41st Olympiad, and the reckoning will place the _Argonautic_ Expedition about 44 years after the death of _Solomon_, as above: and in the days of _Thales_, the Solstices and Equinoxes, by this reckoning, will have been in the middle of the eleventh Degrees of the Signs. But _Thales_, in publishing his book about the Tropics and Equinoxes, might lean a little to the opinion of former Astronomers, so as to place them in the twelfth Degrees of the Signs. _Meton_ and _Euctemon_, [80] in order to publish the Lunar Cycle of nineteen years, observed the Summer Solstice in the year of _Nabonassar_ 316, the year before the _Peloponnesian_ war began; and _Columella_ [81] tells us that they placed it in the eighth Degree of _Cancer_, which is at least seven Degrees backwarder than at first. Now the Equinox, after the rate of a Degree in Seventy and two years, goes backwards seven Degrees in 504 years: count backwards those years from the 316th year of _Nabonassar_, and the _Argonautic_ Expedition will fall upon the 44th year after the death of _Solomon_, or thereabout, as above. And thus you see the truth of what we cited above out of _Achilles Tatius_; viz. that some anciently placed the Solstice in the eighth Degree of _Cancer_, others about the twelfth Degree, and others about the fifteenth Degree thereof.
