Hi Monganaut, your response brought a huge smile to my face, why?, well the reference to Neolithic language possibly being connected to the Welsh language. As a schoolboy growing up in Amlwch, Anglesey, we had to learn Welsh and the thought that I might have been able to ask one of the builders at Stonehenge 'Where is the train station' quite made my day. On a more serious note, I think the whole question of language during the building of the great monuments and the beginning of trade with Europe is fascinating and definitely my winter project. As for the river at Amesbury still meandering along the same course it did over 4500 years ago I will have to leave to the experts, at least it removes one other variable from the equation (and Lord knows there are enough)
