How controversial is the truth?


Yesterday I gave a talk to a group of Oxford college alumni, and I was introduced as "someone who holds very controversial views on the origins of the bluestones".  It was all very jolly, and my talk was well received, but the introduction got me thinking. Is it really my views that are controversial, or should that word be used to describe the views of the other lot?

To put it simply, if we forget about druids, giants, aliens and Merlin the Wizard, there are two views of the bluestones at Stonehenge:

1.  The bluestones (43 of them, and maybe a few more originally) are glacial erratics that were scattered about in the Stonehenge landscape before they were gathered up and built into the stone monument.  In all of the other Neolithic and Bronze Age stone monuments of the UK, that is exactly what happened -- suitable stones were found and used locally, involving minimal effort.

2.  The bluestones (80 of them, nearly half of which have mysteriously disappeared) were quarried from rock outcrops in West Wales and transported about 380 km to Stonehenge by our Neolithic ancestors -- carried as an act of reverence because they were deemed to be sacred or magical. There is no other example in British prehistory of such an enterprise, and no evidence anywhere of a technique of long-distance stone transport being developed, reaching a climax, and then declining. In other words it was a complete anachronism or aberration, out of place and out of time.

Now which of those alternatives qualifies as more likely to be true?  Which might be considered normal and thus predictable, and which is eccentric and controversial?  Think Occam's Razor and Hitchens's Razor.  This is from an old post on this blog:

"The burden of proof regarding the truthfulness of a claim lies with the one who makes the claim; if this burden is not met, the claim is unfounded and its opponents need not argue further in order to dismiss it. It is named, echoing Occam's razor, for the journalist and writer Christopher Hitchens, who, in a 2003 Slate article, formulated it thus: "What can be asserted without evidence can be dismissed without evidence."

"... extraordinary claims require extraordinary evidence...."....... on the basis that this is an elementary rule of logic. Well, from every possible angle, Thomas's idea about the human transport of the bluestones was "extraordinary", since there was and is no evidence from Wales that the bluestones (of many different types) were considered special in any way; since there are no other records of the long-distance transport of megaliths for use in ritual or other settings anywhere in the British Isles; since there are no radiocarbon or other dates which can verify the haulage of the stones at the time required by the archaeologists; and since no ropes, sledges or rafts have ever been found which might demonstrate that the haulage project was technically feasible.

In other words, I refuse to accept that my view are controversial.  They are in fact rather normal, unimaginative and unexceptional.  The wild eccentricities and claims of irrational behaviour all go with option number two, which claims that the bluestones were carried or hauled across country, without a scrap of evidence ever having been produced in support of the hypothesis. Assertions are not a substitute for facts. As I asked at the head of the post, how can something that is most likely, on the balance of probabilities, to be true, ever be considered controversial?

Craig Rhos-y-felin: no wedges and no quarry

ABSTRACT

This article challenges the claims made by Parker Pearson et al (2022a) that there is a Neolithic bluestone quarry at Craig Rhos-y-felin and that rock wedges used in the quarrying process have been discovered. The current authors suggest that the evidence for monolith quarrying at Rhos-y-felin and Carn Goedog does not withstand scrutiny, and field research at the Rhos-y-felin site suggests a long history of crag disintegration and rockfall debris accumulation, with Late Devensian glacial and fluvioglacial deposits overlain by Holocene colluvium and other slope materials. The engineering features listed by the archaeologists are disputed, and it is suggested that the radiocarbon evidence from the site also falsifies the quarrying hypothesis. The present authors do, however, accept that there is evidence of a long history of intermittent occupation by hunting and gathering parties, and it is proposed that they might have used Rhos-y-felin as a source for sharp-edged disposable cutting and scraping tools. The use of rhyolite rock wedges in Neolithic quarrying makes no sense from a rock mechanics standpoint, and after examining the fractures in which the wedges were found, it is pointed out that not one of them would have been of use in the extraction of a viable stone monolith or orthostat. Finally, the current authors point out that the "Stonehenge narrative" involving quarries at Rhos-y-felin and Carn Goedog, a "lost stone circle" at Waun Mawn, and stone transport to Salisbury Plain is seriously damaged by recent research publications and should be abandoned. It is a matter of regret that Parker Pearson et al have ignored two detailed Rhos-y-felin papers written by the present authors and published in 2015.

====================

Herewith a short explanation of why this article is not being published in a mainstream peer-reviewed journal.  Multiple reasons. When we had finished modifying the article in line with the recommendations of our own reviewer,  we looked at various options and and decided to submit to one particular archaeology journal that seemed suitable.  But immediately we bumped into problems.  One editor gave us advice as to how the article could be modified for maximum impact, and another editor in the team gave us directly contradictory advice.  So we did some tweaking and submitted it, to find that it was then rejected on the recommendation of a single referee who was clearly unfamiliar with the locations, the background and the articles already published about Rhosyfelin.  In a somewhat chaotic report he / she said at first that the article should be more detailed and evidence-based, and then wider and more generalised. Then more specific to the site in question, and then less specific. We could not make head or tail of what was required of us.  The basic issue seemed to be that two geomorphologists and one geologist had the temerity to question the interpretations of professional archaeologists, including one who has a very high profile!   Rocking the boat!! Outrageous!!   The editor gave us the option to rewrite and re-submit, maybe to another journal in the same "stable".  That was not an issue -- we have all rewritten things and resubmitted them in the past.  But we sensed that we were not going to get anywhere, and decided to explore new pastures.

Immediately we bumped into the problem of submitting an article that was partly archaeological to a geological or geomorphological journal, or of submitting an earth science article to a journal specialising in archaeology.  Even before seeing the draft manuscript, a number of editors suggested that our article fell outside their guidelines and that we should try elsewhere.

But the greatest problem encountered by us (three old codgers) was that we are no longer affiliated to any academic institutions -- and this means that we do not have access to any funding to cover the article publication fees that are nowadays charged by virtually all of the "open access" journals which are owned by Wiley, Taylor and Francis or Elsevier.  Most of them do not even give the editors the discretion to waive the fees.   In addition, the submission process is standardised and extremely intimidating and bureaucratic -- things have changed rather a lot since the days when I could just submit a PDF to a journal editor and expect to receive in due course a couple of peer reviews (sometimes anonymous, sometimes not) pointing out flaws and suggesting improvements.

So we are somewhat disenchanted with the journal publication process as it currently exists, and much prefer to place material onto Researchgate or Academia, where it genuinely is available for anybody to scrutinize.    Further, we have discovered that many of the peer-reviewed journals nowadays require authors to declare in writing that they will NOT copy their articles onto Researchgate or Academia.  The journals are not "open access" at all, but appear to be intent on limiting their readers to a small and select group of researchers who inhabit the ivory towers.  There are exceptions, and we applaud them -- but they are few and far between.

There is also the question of declining standards in the pages of the journals that were once the pillars of academia.  I have been very critical in many of my blog posts of journal articles that should really never have seen the light of day.  That may be partly because editing standards have declined, and it may be that a system in which the authors of articles can effectively choose their own referees encourages cronyism and reduces critical scrutiny.  Just the other day I read a long article in which the author bewailed the fact that the peer review system has effectively collapsed because there are too many journals, too many articles and too few qualified reviewers.

For better or worse, the Researchgate publishing route seems to us to be preferable from a number of standpoints. True, those who publish articles on its web site do not have the same "status" as those who use mainstream journals, but there is much to be said for community science which is democratic,  inclusive and even a little subversive, as long as it is accompanied by options for feedback and discussion such as we have on this blog and on many others.

Thanks to Chris Johnson for this photo of some of the "wedges" put on display in an exhibition in Belgium in 2018, curated by MPP.


PS.  Over the last couple of years I have done a number of posts on this blog about the wedge claims.  Just type "wedges" into the search box and all will be revealed.





One of the open joints at Rhosyfelin that was supposedly targetted by the Neolithic quarrymen with the use of wedges.  You can just see the broken rock debris that has fallen into the joint.


Another wide joint, and another broken bit of bedrock. The idea that fragments such as these are deliberately placed "wedges" is quite preposterous, and demonstrates a cavalier disregard for natural processes.

Did the Vestra Fiold "quarry" provide standing stones for the Ring of Brodgar and the Stones of Stenness?



The Vestra Fiold "quarry pit" from which, so it is claimed, firm evidence of quarrying was extracted.  The evidence is much more equivocal than claimed.  (Photo: Colin Richards)


There's a new article about the Vestra Fiold "quarry" on Orkney, which is very concise and nicely produced but which tells us nothing new.  Here it is:


Vestrafiold – the megalithic quarry
SUNDAY, APRIL 23, 2023

But on examining it, I realised that it is based on a whole string of assumptions going back quite far into the archaeological record, all based on the assumption that there is a stone quarry there that has provided monoliths for the famous stone settings at the ring of Brodgar and the Stones of Stenness, some miles to the SE. Everybody cites the older "authorities" who described it as a place of monolith quarrying, but nobody seems to have asked any serious questions about that key assertion.  And of course Colin Richards has confirmed this -- in the eyes of many -- in a number of publications.  So powerful has this assertion been that RCAHMS has confirmed it as a scheduled monument, apparently without any serious examination of the evidence.  Colin's narrative about quarrying and stone movement is just as fanciful as that of MPP with regard to Rhosyfelin -- and of course, because he was part of the digging team,  he may well have been more than a little involved in the interpretation and description of the features at the latter site......


But things are not quite that simple.  Many years ago Aubrey Burl explored the idea that the stones at the two famous sites near the Ness of Brodgar were collected up in the immediate neighbourhood, and were either glacial erratics or stone slabs lifted from nearby stone extraction pits. It's known that the monoliths are of seven different rock types -- which immediately disposes of the myth that all of the monoliths came from a dedicated quarry at Vestra Fiold.

There are two other scheduled monuments in the vicinity of Vestra Fiold, a Neolithic long cairn and a Bronze Age (?) enclosure  -- and I have never seen a serious consideration that any quarrying at Vestra Fiold may simply have been devoted to the provision of local stone for local use.

And on the matter of geology and geomorphology, the glacial erratic  hypothesis has simply been ignored in most of the literature about the Orkney megalithic sites.  And yet it has been known for well over a century that the Stromness Sandstones outcrop both to the south and the north of the Ness, and that the monoliths used in the famous stone settings COULD have come from the SE, given that there was a SE - NW movement of ice across Orkney on at least one occasion during the Quaternary.


As I said in 2014: I have seen nothing in the geological work which might indicate that the orthostats in the Ring have come from the north of the island rather than from the south -- and there is one other small piece of evidence in that one stone found at the Ring appears to belong to the Eday Group, which outcrops in the south but not in the north. That might be an indicator of glacial transport from the south coast of the island towards the peninsula on which the Ring is positioned.


The last glaciation in Orkney, Scotland: glacial stratigraphy, event sequence and flow paths
October 2016
Scottish Journal of Geology 52(2)
DOI: 10.1144/sjg2016-002

Adrian M. Hall, James B. Riding and John Flett Brown

This 2016 paper by Adrian Hall and colleagues just considers the Devensian glaciation, but it confirms the log-held belief of ice transport of erratics from SE towards NW.  I'm going to remain profoundly sceptical about the Vestrafiold "monolith quarry" until somebody comes up with some convincing geological evidence in favour of it.........

Birmingham's Brilliant Boulders


These are the plaques on some of the erratics listed by the boulder enthusiasts of South Birmingham.  I wonder if EH would give permission for similar plaques to be stuck onto the bluestones of Stonehenge?  That might help to get some common sense into the interpretation of the old ruin, and help to suppress some of the wilder fantasies that are doing the rounds......

I'm full of admiration for those excellent people in South Birmingham who have recognised erratic boulders in their locality as a fantastic asset for tourism and also commumnity cohesion.  They have a splendid Facebook page, full of photos and bits and pieces of publicity and interpretation.  They claim that the bulk of the boulders have come from the Arenigs in North Wales, and that they were transported by ice around 450,000 years ago.

https://brian-mountainman.blogspot.com/2016/10/erratic-behaviour-in-midlands.html

https://brian-mountainman.blogspot.com/2022/10/the-midlands-erratic-hunt.html

They value their erratics so highly that they sometimes give then a nice wash and brush-up, and careful records are kept of erratic sightings in the woods and in other places where the habitat is suitable.



There are 8 (at least) boulder trails, with accompanying guides on the web site.  There are also some well written notes on the erratic hunters web site, such as this one:

The end of a giant erratic

 


Apparently this giant erratic on the moraine above the Mer de Glace is no more.  It measured 12m x 19m, and was in a very precarious position.  It fell in March 2023 and broke into many small pieces, none of which reached the glacier surface far below......

QRA website revamp

 

The QRA web site has had a serious makeover, and it how has a fresh and modern look.  There is also a change of policy, and copies of the Quaternary Newsletter are genuinely open access, available to everybody, regardless of academic affiliations or accessibility to "reading cash"!!

Here is my last article in the new QN format:

https://www.qra.org.uk/mp-files/qn158_1_late-devensian-ice-free-corridor-in-pembrokshire.pdf/

It's been well received, and I have received no notifications thus far about any violent disagreements from others working in this field.

Exclusive interpretation rights?


April, 2015, at Rhosyfelin, right next to a public footpath.  Who "owns the hole" and who is responsible for the mess?  Is there some ethical reason why independent observers should refrain from visiting sites like this and interpreting what they see?


Does an archaeologist who digs a hole in the ground have an exclusive right to describe and interpret that location?  

That's the question that comes to mind, following a communication I have had from an archaeologist who accuses me and my colleagues John Downes and Dyfed Elis-Gruffydd of unprofessional conduct because we have had the temerity to look at and interpret some of the things turned up at Rhosyfelin in 2012-2015 by Mike Parker Pearson and his team.   OK -- I can understand that there is some sort of etiquette surrounding archaeological excavations, and an assumption that there is "ownership" of the things that are revealed by the diggers that might not have been visible beforehand.  And it's commonly accepted that the diggers have the right of first publication.  But what happens next?  Are the rest of us supposed to then accept without question that the observations made by the diggers are accurate, and that their interpretations are reliable? Heaven forbid -- if that were the case, there would be no academic debate, and in many cases falsehoods, technical failingss and mis-interpretations would trump the truth.

In my own field -- geomorphology -- sites discovered and excavated by me in Pembrokeshire have been re-examined and reinterpreted subsequently by many others.  I don't have any problem with that, and have been involved in many energetic debates about them inside and outside of the published literature.  In Iceland, Greenland and Antarctica sites discovered, described and interpreted in learned journals by David Sugden and me have been visited and subjected to detailed analysis by a new generation of field workers.  That's the way it should be, and our pioneering efforts have been rewarded by the Antarctic Place Names Committee through the listing of Sugden Ridge and John Glacier.  Of course, the sites recorded by geomorphologists tend to be landforms and cliff exposures which remain available for future research once the initial assessments have been made.  That fact alone imposes a certain discipline on those who record sites for the first time; to put it crudely, you know you cannot get away with bullshit, because others will come and check things out.  

In contrast, an extra duty of care is imposed on archaeologists who dig holes in the ground (often at vast expense to the taxpayer) to describe and interpret things honestly and competently, because once the holes are filled in, nobody can check for misinterpretations, selective evidence collection and research bias. 

To return to Rhosyfelin.  I absolutely refute any charge of misconduct or malpractice on our part.  When the dig started I offered to help with a "geomorphology" input in conversations with several of the research collaborators, with no response.  On one occasion I arranged to meet Prof MPP at a certain time at the site, and he failed to turn up.  On several occasions, in discussions after public lectures, I sought to open discussions on matters of interpretation, and the project leader simply refused to engage.  We acknowledged his right to first publication, and held back while several articles were published by the research team.   But when we published two peer-reviewed papers in 2015, MPP and his team simply refused to acknowledge their existence, and over the eight years that have elapsed since then there have not been any citations of our research.  Why not?

As for access to the dig site at Rhosyfelin, there were no restrictions to access because it was immediately adjacent to a public right of way.  Hundreds of people visited the site during September of each year while the dig was going on, and hundreds more visited during the other months and were able to examine "the evidence" since the pit was always left open, sometimes partly covered with a plastic sheet.  In the absence of the excavation team, it was possible to make truly independent observations,  without any pressure to accept the party line or interpret things as required by the senior archaeologists.  The key evidence on the rock face and the local landforms, examined by me and my colleagues, had nothing to do with the dig, and most of this evidence (described in many posts on this blog) is still accessible today, long after the end of the archaeological investigations.

Carn Goedog and Waun Mawn are both on common land, and so the digs at both sites within the last decade were completely open to the public.   The digs could not have been "fenced in" as they might have been on private land.  Again hundreds of people wandered about and looked at things both when the diggers were present and when they were not.  A number of guided tours were arranged for local groups with an interest in archaeology and local history, which was commendable -- but of course on those occasions the narrative given to participants was the one that we are now all familiar with, as featured in popular magazines and in TV programmes. And as we now know, that narrative was not exactly balanced or reliable......... 

What might have happened if there had been no independent evaluation of the three sites, at Rhosyfelin, Carn Goedog and Waun Mawn? To put it mildly, falsehood would have been perpetrated on a substantial scale.  Nobody would have questioned the reliability of the three crucial papers published in Antiquity journal in 2015, 2019 and 2021, and almost certainly all three sites would have been designated as Scheduled Ancient Monuments.  Just think about that for a moment....... and you may wish to recoil in horror.

As it is, in spite of the difficulty of getting "scrutiny" articles published in learned journals, my colleagues and I have behaved ethically at all times.  We have respected the right of "first publication" by Parker Pearson and his team.  We have tried, through our own articles and in social media, to alert them to our concerns about their methods and their interpretations, which were of course ignored.  The only one who did engage, to his credit, was "Myris of Alexandria", whose identity remains a great mystery.......   But it's also a great disappointment that nobody else (from a team of more than a dozen quite senior academics) was prepared to engage in any realistic debate, maybe because they thought that discussing matters of interpretation on a blog was a rather disreputable activity.

So here we are.  On the one hand we have a string of learned papers from geologists and archaeologists, all promoting a bluestone quarrying and human transport narrative, and on the other hand we have detailed scrutiny of those papers and the presentation of independent observations and interpretations in the posts and comments --  on this blog and on other blogs in the field of archaeology.  Maybe that's the way of the world just now. To the right, experts who have access to the traditional means of academic publication, and who have reputations to enhance (or destroy!) -- and to the left other experts (because we ARE experts) who have the skills and enthusiasm to "knowledgeably scrutinize" what is in print and to find it wanting.

So regardless of who occupies the ethical high ground here, the truth is gradually emerging.  Rhosyfelin as "the Pompeii of Neolithic quarries"? Gone.  Monolith quarrying at Carn Goedog "on an industrial scale"?  Gone.  Proto-Stonehenge at Waun Mawn?  Gone.  The imprint of bluestone 62 at Waun Mawn? Gone.  People and animals from Preseli found at Stonehenge, based on the isotope analysis of bones and teeth?  Gone.  These mistakes have been admitted in follow-up publications by the same researchers who originally made the faulty claims.  But make no mistake about it -- if it had not been for the subversive science, detailed scrutiny, and arguments about interpretations by those of us who dabble in social media, those follow-up papers would never have been written.  And multiple falsehoods would all now be regarded as the established truth.
