OK I've been quietly browsing these 'astro' posts but I have questions...
So what? I mean what IS Orion? Why would they want to copy it? Why not another star feature?
From a young age we are taught about the plough and it pointing to the north star. But Orion? Does it point to another feature or direction?
Why that constellation and not another? Cos it looks like a man, vaguely?
Do we really know they interpreted it as?
Hmmm.
I think I'm with the Too Good to be True brigade on this one!
I think it's more likely the three henges were supposed to be in allignment and it went astray, due to eg the lie of the land or ownership or foggy weather or wonky eyesight...
