PRECESSION

“Precession calculation is a vital tool for the historian to help him understand ancient man, whose religion was often directed to the ‘sky gods’ and thus based on observations of the sky—what today we would call naked eye observational astronomy. It can be thus understood that ancient man built religious monuments and, prolifically, tombs which made use of geometrical astronomy to express astronomical alignments and other phenomena of the sky using symbolic architecture. It further follows that if an architectural feature of a monument is suspected to have been aligned towards a specific star, then, with the use of precession, it is possible to work out the date of such a monument to a fairly good level of precision . By also ‘re-creating’ the sky for a given epoch, we can see what they saw and hence understand further the religious importance of their observations through the design and symbolic expression of the monument .” P. 242, “Precession,” THE ORION MYSTERY (Appendix 2) by Robert G.
