As I watched a documentary recently on the History Channel that discussed the ancient standing stone sites of pagan Britain, I was struck by how often archaeologists are baffled by just how these enormous stones got to their current location on the Salisbury Plain from where they were quarried many miles away.
It seems an unimaginable feat to primitive neolithic peoples some 3,000 to 5,000 years ago (there's much debate). Yet, it is well-known that many of the enormous obelisks of ancient Egypt were floated up the Nile River from much further south where the stone was quarried.
While undoubtedly smaller standing stone site, like those in the Orkney Islands, were constructed by hand, the megalithic sites like Stonehenge may have had some help. No, not the extraterrestrial kind. I mean the River Avon.
To many scholars, like Mike Parker Pearson, head of the Stonehenge Riverside Project, the river is simply seen as the metaphoric passage from the land of the living, as represented by the "live" trees that once formed the lesser known Woodhenge, to the center of death rituals in pagan Britain. But what if the river served as the freeway upon which barges floated these massive stones from their source?
The ditches and berms might have served as canals that further moved the stones to the site where they were floated into position before, once more, brute force was required to haul the stones into place.
Now, I've personally no evidence to bolster this supposition, but I think it would be a fascinating hypothesis to look at for any scholar willing to try.
