Excellent points here, thank you.
And in the 4500 years of flood plain, were there any periods of dry lake bed?
And what is the age of Aries, which I say might explain the ram's horn hairdo or helmet of the first figure to the East of Silbury?
Age of Aries, Wikipedia... http://en.wikipedia.org/wiki/Age_of_Aries#The_Age_of_Aries_.28The_Arian_Age.29
Heindel-Rosicrucian based interpretation: began in ca. 1658 BC and ended in ca. AD 498
Neil Mann interpretation: began in ca. 2150 BCE and ended in ca. AD 1.
Constellation boundary year:
Shephard Simpson interpretation: began ca. 1875 BC to ca. 100 BC
So the Ram's horn hairdo might fall within the 4500 years you mention, in a time of extended dryness? Or was it entirely flooded, for that entire time?
Just asking!!! PS, you are educating me, and a big thanks.
