Yep. "Related" monuments might be 30m and 2,000 years apart.

Which would suggest that for the equidistance to be significant, the people who laid the sites out would have to have understood the significance of correcting for slope in surveying (which they might have done).

The gist of the equidistance theory seems to be that the monuments are equidistant in real terms (i.e. as the crow hops, from above, measured on a map, etc) rather than what you would get from simply taking a length of twine to an uneven location and laying it out or holding it taut between the sites, as this would make them not equidistant when surveyed and measured on a map.

That's what I think, purely from site visits. But I've never measured anything to test it out!
In the end, however - unless we are accusing Mr Leighton's measurements of being incorrect (which, having ratified many of his fieldnotes myself over the years, I certainly am not) - it surely again all comes down to what are the odds of this occuring without intent? Do we honestly believe BA engineers did not possess the skill required to accurately survey the landscape? Really? Furthermore it appears there is no well known standard for calculating such odds, so would not a 'probably.... possibly, even... although impossible to prove' caveat be more appropriate than 'nonsense?' Unless a coherent explanation can be given as to why these monuments are arranged just so - but nevertheless do not form an associated grouping - other than through sheer random placement (in my view very unlikely) I would have to ask, well, prove they are not.

The difficulty I have is with the idea that equidistance is more important than topography in placing a particular monument somewhere.

Because for me, most BA and Neolithic monuments appear to be placed because of where they "ought" to be, not how far or otherwise that is from any other monuments in proximity. For every group where the measurements (on a map, not on site) suggest distance is important, there must be 100 more groups where the measurements do not.

At Maen Llia, the placement of the Rhyd Uchaf cairn seems to me to be based more on the fact that it's on a prominent little hillock in the landscape, between branches of the watercourse, looking down the valley, than how far it is (on a map) from Maen Llia. 10 yards either way and it would be in a stream, so the position is dictated by the terrain not the distance from something else. And the cairns on Fan Nedd are surely placed in the most suitable location based on the underlying topography, not how far they are from each other.

I'm not discounting the possibility that a particular monument may be deliberately placed x metres from another monument, but surely that can't apply to the vast majority of monuments that we see in the Welsh uplands? There seem to be far too many other factors involved that would override equidistance, aren't there? Not least of which is pure practicality in a very uneven landscape criss-crossed by streams.

"In the end, however - unless we are accusing Mr Leighton's measurements of being incorrect (which, having ratified many of his fieldnotes myself over the years, I certainly am not)"

The measurement wss done a map , not in the field , anyone who can use a ruler can do it and was first noted by Mr Griffithsin the 60's not Leighton .

"it surely again all comes down to what are the odds of this occuring without intent? "
That was the argument for ley lines ,until statisticians blew that one out the water .at least the believers had an explalnation , route markers , for wayfarers , or subtle energy , spirits , fairies , ufo's .

"Do we honestly believe BA engineers did not possess the skill required to accurately survey the landscape? "

Of course they could , but why would they and where are the other examples ? If believe they are intentional see my examples which would suggest that they were bieng done on more sophisticated level and much earlier on Arran . Looking forward to your fieldnotes with the tape measure .

"Furthermore it appears there is no well known standard for calculating such odds, " Ask a statistician first .


"so would not a 'probably.... possibly, even... although impossible to prove' caveat be more appropriate than 'nonsense?'
The "nonsense " context came from two comments “its geometric relationship with nearby Bronze Age monuments points to its prehistoric origins .” and “The site lies equidistant from Maen Llia and concentric 'hengiform' earthwork within the triangle and thus is probably related to them.”which are nonsense ,equidistance is not a measure of association or dating ,even the old chestnut of Glastonbury , Stonehenge and Llantwit Major never claimed that for dating .


"Unless a coherent explanation can be given as to why these monuments are arranged just so - but nevertheless do not form an associated grouping - other than through sheer random placement (in my view very unlikely) I would have to ask, well, prove they are not."
Prove that they weren't built by fairies ,god , Egyptians ,ancient astronauts ,are not part of an ancient energy grid .Proving negatives is very difficult and often impossible and anyone who believes in any of the above is not likely to be swayed by argument

No, not at all. But not surveying for the same reasons surveyors do now.

There were no maps or drawn plans, so surveying things to ensure that they are accurately placed when viewed on a map would seem irrelevant.

They certainly did not have theodolytes, so any horizontal measurements would have to be taken by either using rope or twine, or rods, etc (which would not lead to equidistance on a map for the reasons already mentioned), or by pacing (which is even less likely to result in accurate equidistance when viewed on a map).
