Colures, in the ancient Sphere of fixt Stars, in the 
fame places as Hipparchus tells us they had been fup- 
pofed by Eudoxus many Centuries oi Years after Chi- 
ron. His words are thefe, \v J'i <p\uri KtlSrcu 
r»v Ki'pa.KriV, >y Ta ra vi^ta nrh<tT'&'. Xhis, un- 
doubtedly, was the Pofitiori oF the Colure of the Ver- 
nal Equinox many Ages before Eudoxus \ but whether 
fo old as Chiron^ and the Argonaut ick Expedition, I 
ihall not undertake at this time to enquire ^ but only 
obferve, that P. Souciet in his Fafles du Monde^ or A- 
bridgment of his Chronology, prefixt to thefe DifTer- 
tarions, makes the Argonaut ick Expedition 1467 Years 
before our jEra of the Birth of Jeius Chrifl ; and the 
taking of Troy 1388 Years before it, which Date is 
120 Years fooner than the P^r/4// Chronicle, read and 
publiflit by our Learned Selden in his Marmora Arunde- 
liana^ makes it ; and above 50c Years earlier than the 
time affigned by Sir Ifaac Newton. 
Now both of them making ufe of the fame Premif. 
fes, it may feem ftrange that their Conclufions Ihould 
be fo widely diftant : And indeed upon a PrsepofleiTion 
that the /irgonautkk Expedition and the Siege of Troy 
could not have been lefs than loco Years before Chriif, 
I mud own, 1 was at firfl fomewhat prejudiced in fa- 
vour of P. Souciet^ taking his Calculations for gran- 
ted ; and not having feen ^Sir Ifaac s Work. But ob- 
ferving that he quotes Sir Ifaac laying, that in confe- 
quence of what Hipparchus has recorded from Eudoxus.^ 
the Equinoctial Colure in the old Sphere was about 
7*^ 36^ from the firll Star of Aries., I was refolvedto 
examine the matter with due Attention, efpecially 
fince the Good Father feems to triumph over his Ad- 
verfary, and to treat a Man of his Figure in the Com* 
mon-wealth of Learning in a very ludicrous manner, 
notwithdanding the feveraldne things he fays of him to 
palliate it. 1 find
