Since when did the sarsens at Stonehenge come from a long way off? HH Thomas (among many others) thought they had come from the neighbourhood, and I can't see any evidence to suggest that he was wrong on this one. The fact that Atkinson developed a great story for the sarsen transport doesn't mean it happened. Newgrange? Small white quartz stones from a long way off as "ornamental features" -- wouldn't have a problem with that being done by chaps with haversacks. Old Keig? Where's the evidence that the big stones are not erratics? The Orkney examples -- there are mentions of quarries in connection with the standing stones, but I'd like to have a look at these sites with reference to ice-movements / erratic distributions as well. At Brodgar, Renfrew thought that the stones had come from the ditch around the stones, and not from the so-called quarry.

In the "The great stone circles project" (Antiquity 2005) there are lots of references to quarries, but somewhat surprisingly the archaeologists involved fail to refer to erratics at all..........

What do I mean by "local"? Thorpe and Williams-Thorpe (Antiquity 1991) looked at all of the UK sites and found that the megalith builders used stones from up to 2 km away quite often, but that there was no case of stones being carried more than 5 km. So let's refer to all of these sites as "using locally-sourced stones."


I had noted that you referred specifically to Britain where glaciation could be used to to explain movement of stones over much it's area and assumed that you would be aware of the movement of much bigger stones over much greater distances than we are talking about here , e.g. Baalbeck , Collosi of Memnon etc . There is no argument about these efforts and glaciation can't be involved so we do have precedents for the movement and quarrying of stones but maybe we shouldn’t expect too much from the occupants of our little island .However the point is the importation not the size or effort .
Bringing something 5K no matter how big particularly when the same quality can be found locally is an important pointer to our understanding . Nevertheless some of the biggest stones at the Bru came from over 5km away .That haversack of quartz probably came 80 Km , that is what matters .
The recumbent at Old Keig could be an erratic but if it is, it had been quarried before glaciation and would therefore be a unique example of Paleolithic masonry .
Obviously builders of monuments use local material , but not all do .
