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 deg..
51'. as above: count backward 1 Sign, 6 deg.. 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 deg.. 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 deg.. 26'. 8": and the Longitude of
_Arcturus_ [Virgo]. 13 deg.. 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 deg.. 53': and by consequence
the _Lucida Pleiadum_ had, since the _Argonautic_ Expedition, moved from
the Equinox 4 deg.. 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
