<HTML>Dave and Stephen:
Thank you kindly for your replies. Consider this, however: 10450 yrs. B.C.+2000 = 12450 yrs which is nearly half the precessional circle, that means the sun must also travel nearly half way around its path: the ecliptic, or 174*.
Yet, if you take the point of Aires, as given by your software, Beta Virgo (11hrs 50' 46" ) or 177* from the present point of Aries (vernal equinox) the sun has only covered 148* of the ecliptic in 12450 yrs, which is clearly impossible. What is wrong here? Care to have a go?
