How much do we know about Stonehenge? Less than we think. And what has Stonehenge got to do with the Ice Age? More than we might think. This blog is mostly devoted to the problems of where the Stonehenge bluestones came from, and how they got from their source areas to the monument. Now and then I will muse on related Stonehenge topics which have an Ice Age dimension...

Parc y Gaer Roman villa, Meline parish
Possibly the most interesting thing to come out of the work in the Pensarn area is the discovery (during the search for a Neolithic Proto-Stonehenge) of a Roman villa site. This was discovered by geophysical surveys in a field in Meline parish in September 2016, and reported to a student conference in April 2017. The field is about 500m to the east of the Pensarn Lane where the 2016 dig took place.
It's great to see students working on a project like this, and reporting their work responsibly. I'm sure we all wish them well, and look forward to seeing what the 2017 dig has revealed. The name Parc y Gaer means "fort park" or "fort field" -- I'm intrigued to know whether that name is the traditional name used by the farmers of this land down through the years. Here is the abstract from the spring conference:

Inebriated archaeologists dig large hole in Pembrokeshire field
Couldn't resist this one -- with due acknowledgement to the Bluestone Brewery Facebook page....... always happy to give a puff for our friends and neighbours!
Seriously though, the diggers were probably all perfectly sober and well organized. This is a nice pic of the latest Pensarn dig by MPP and his team, showing how thin the sediment layer is here -- not much more than a metre or so before the broken bedrock (looks like foliated rhyolite) is encountered. There is a lot of frost-shattered and broken rhyolite, and some foreign stones including bits of dolerite. Some of the stones look as if they might have been burnt -- are there hearths on the site? I wasn't invited to take a close look when I called over there the other evening.........
I don't want to sound sour. It sounds as if there are some really interesting things coming out of this dig, which we can all celebrate. I have no inside information, and need to check what is in the public domain, as well as separating rumours from facts. But all being well, I'll be in a position to report on what MPP has said within a few days.
PS -- slightly edited. I thought there might be till here. Now, having had a closer look, I have my doubts. Its distribution is very patchy.
MPP, The National Geographic and the encouragement of pseudo-science
I was interested to see this little phrase in the Antiquity article by Mike Parker Pearson et al in December 2015:
"The theory that the stones were carried by glaciers, transported during an Ice Age to Salisbury Plain or its margins (Kellaway 1971; Thorpe et al. 1991; Williams-Thorpe et al. 1997, 2006), has not been refuted until now..........."
The implication is that the Rhosyfelin research work, and the assumed identification of that infamous "quarry" has somehow put an end to all this stuff about glaciers. Of course, nothing could be further from the truth, not least because the evidence for quarrying does not withstand scrutiny. As we have seen on this blog, the presence of the "quarry" was decided upon even before the archaeologists descended on the site to dig their rather large hole, and all they were actually doing was seeking confirmation of a ruling hypothesis. Pseudo-science was writ large across the face of the project from day one. The geologists -- Richard Bevins and Rob Ixer -- were complicit in this, even though they started out by simply referring, in their papers pre-2011, to a rather interesting piece of provenancing which linked Stonehenge to the Pont Saeson - Rhosyfelin area, without expressing any opinion as to how the monoliths and the bits of broken rock might have travelled from here to there. By 2015, of course, they were fully signed up to the quarrying hypothesis, as we can see from a string of statements in their publications. Like MPP and his archaeologist colleagues, they had clearly decided to go with the flow. The glacial transport of bluestones was impossible, because the following had apparently told them so:
(Thomas 1923; Green 1973; McMillan et al. 2005; Gibbard & Clark 2011; Clark et al. 2012)
We don't want to go over all that again, but we might as well remind ourselves that Kellaway, Richard Thorpe, Olwen Williams-Thorpe and their colleagues were by no means isolated or out on a limb as far as extensive glaciation was concerned. MPP et al could have cited my apparently unmentionable little book (2008) as well, on the basis that I actually do have reasonable credentials, and that I know more about the glaciation of western Britain than some of those on their list of sceptics. They could have mentioned Judd from the good old days and Alun Hubbard, Tom Bradwell, Nicholas Golledge, Adrian Hall, Henry Patton, David Sugden, Rhys Cooper, and Martyn Stoker (2009) from the days of high-tech glaciology and glacier modelling. These guys know what they are talking about, and they all signed up to a statement in a big and much-cited paper to the effect that glacier ice as far east as Salibury Plain was perfectly possible.
I don't want to get into silly numbers games, but I'm confident that of all the earth scientists who have expressed views on glaciers and Salisbury Plain, there are at least as many who say that glaciation was possible as there are on the other side. And of course, if we apply a little logic, even if there is a Neolithic quarry at Rhosyfelin, it tells us nothing whatsoever about how 43 or so bluestones travelled from A to B.
The thing that worries me more than anything about the pseudo-science swirling around the Rhosyfelin debate is the lack of peer-review and scientific scrutiny of the things the archaeologists have been writing and saying. Let's remind ourselves that over a period of 7 years there is just ONE peer-reviewed paper (in Antiquity in 2015) which presents evidence, discusses its interpretation, and suggests conclusions. That relates just to Rhosyfelin. It's a deeply flawed paper, and I remain amazed that it ever found its way into print. If I had refereed it, it would have been rejected out of hand, with a request for a complete rewrite and resubmission. Apart from that, nothing. There has been no peer-reviewed paper on Carn Goedog. That's incredible, given the huge significance being attached to the site by MPP and his team. We don't count articles in British Archaeology or Current Archaeology, conference papers or "state of play" reports, or even books, because they are not designed for scientific scrutiny and simply repeat assertions and speculations which readers cannot question because they have no evidence to assess. Over seven years MPP and his team have placed no excavation diaries or annual field reports into the public domain, where they can be examined by their peers. They may have submitted annual reports to the funding organizations, as required by the terms and conditions, but if they are not made public these documents might as well not exist. (In contrast, Profs Darvill and Wainwright HAVE followed academic norms by presenting their field evidence in seven annual SPACES reports, all published -- and available for scrutiny -- in Archaeology in Wales.)
I have made a fuss about this on my blog, and am probably therefore viewed as "the enemy" by MPP and his team. But there are big issues here regarding the use of public funds, scientific ethics and university education. Why is the archaeological community not raising hell about an ongoing and high-profile research project which is apparently not overseen or scrutinised by anybody?
http://www.ucl.ac.uk/archaeology/research/directory/stones-of-stonehenge-parkerpearson
I have been pondering on the whys and the wherefores of this miserable state of affairs. Could the blanket of secrecy over the Stones of Stonehenge project be down to some mysterious contract which MPP has signed with one of the project funding partners? I cannot imagine the Society of Antiquaries or the Royal Archaeological Institute insisting on "no unauthorised publication" or "first use of information" clauses in funding contracts, since they want material out there in the public domain, preferably as quickly as possible. So the culprit has to be the National Geographic -- either the magazine or the TV Channels. If you look at the Society's web-site, it offers grant aid to exciting projects, and purports to encourage publication everywhere and anywhere -- but Mike has admitted at various times to constraints placed upon him and his team by the National Geographic. I will speculate, therefore, that Mike has signed an incredibly restrictive contract which gives the National Geographic a "first use" option on anything coming out of the digs in Pembrokeshire. This is, I think, supported by the manner in which the National Geographic has issued press releases and publicised spectacular events associated with the digs (you know the sort of stuff) before the rest of the media swings into action. Is there a very large TV contract also lurking in the background? Does MPP have to deliver a TV documentary spectacular the like of which the world has never seen before? Does he have to deliver before he gets paid? To hell with science -- all that matters is IMPACT.
Best Neolithic quarry ever discovered, anywhere in the world. Heroic ancestors quarrying chunks of rock in a Welsh wilderness and then carrying the monoliths all the way to Stonehenge just because they embody the spirits of the ancestors? An amazing Proto-Stonehenge in Wales, used and then dismantled -- yes indeed -- that'll do nicely! Assemble the cast of thousands -- filming starts on Thursday week........

Is Tim Darvill a quarrying sceptic?
I have been looking back over a few old articles, and on looking at one of the more balanced pieces on the MPP quarrying and Proto-Stonehenge hypothesis, by Tia Ghose, I came upon this snippet which demonstrated a certain scepticism.
https://www.livescience.com/53065-stonehenge-bluestones-quarry.html
.............However, the evidence in support of the theory is scant: a few traces of burnt material and one oddly positioned rock. And not everyone is convinced that these clues point to an earlier Stonehenge-like monument.
"While this work adds some detail, it doesn't change the main picture," said Timothy Darvill, an archaeologist at Bournemouth University in England, who has excavated at Stonehenge but was not involved in the current study. "The Preseli Hills are extensive and geologically very complicated, with the result that matching stones to particular outcrops is fraught with difficulties."
In addition, it's possible that much of the archaeological material uncovered is "entirely natural" — not evidence of human work on the landscape, Darvill said.
I hadn't noticed the quote from Tim Darvill on a previous reading, and it's rather interesting that he says pretty well exactly what Dyfed Elis-Gruffydd, John Downes and I said in those two articles which MPP and his colleagues so studiously ignore!
The Making of Prehistoric Wiltshire
The Making of Prehistoric Wiltshire (2017)
by David Field and David McOmish
Amberley, 160 pp, £16.99
Brief Review
I have been browsing through this pleasant book, which concentrates more on geography and history than on archaeology. For the authors, landscape is not exactly everything, but they recognize that spatial relationships have been somewhat neglected in the bulk of archaeology texts in recent years, and they seek to redress the balance. In their introduction they talk of "the archaeology of landscape", and the words "land" and "landscape" crop up frequently throughout the text. The chapters are organized not by conventional time periods, but by the differing landscape impacts of particular cultures. So we hear about the first monuments, agricultural landscapes, enclosures, forts, farms and so forth -- all with an emphasis on how successive waves of settlers adapted what was there before and brought new features into the landscape. The natural landscape underpins or shapes everything, and there is a nice emphasis on associations, development, abandonment and redevelopment during the ebb and flow across the millennia.
What I particularly like about the book is that it is evidence- or fact-based, and mercifully free of speculation and fantasy. Not a sign of hyperbole anywhere. The bluestones are briefly mentioned, but there is nothing about so-called quarrying at Rhosyfelin and Carn Goedog. Stonehenge hardly figures at all in the text -- and that's really rather refreshing! As a result of this rather fastidious attention to accuracy and impartiality, the book reads at times like a slightly dusty academic tome -- so in that sense it bears comparison with "Stonehenge and its Landscape" (1995) by Ros Cleal and her colleagues, which is also mercifully free of fantasy. But that vast tome is now somewhat dated, and the Field / McOmish book is up-to-date, as well as being a short and easy read.
There are a few gripes. The system of notes gives the book a rather academic feel, and might deter the non-specialist reader. I found the habit of using archaeological long-hand for dates extremely irritating; what on earth does this mean? "..... dating to the late third / early second millennium cal BC".......... If they meant 4,000 years ago -- or whatever -- why didn't they just say so? The book's design leaves much to be desired, with figures that are almost all over-reduced and covered with a grey wash, making them mostly incomprehensible. The maps are also difficult to read because of the grey obsession. The colour plates have a very flat appearance, largely because the book is printed on a matt or silk paper, and I cannot understand why they are all clustered in a group near the middle of the book. There is absolutely no reason for doing that, with modern printing technology, and they would all have been much more effective if they had been placed in their "right" positions in the text.
But these are minor gripes. Overall, an interesting and reliable book, thoroughly recommended.

The 2017 Pensarn dig
I had a pleasant chat with Adam Stanford this evening, having gone over to Pensarn to see where the current dig is being conducted. He was flying his drone at the end of the day's work.
Out of respect for the diggers, I won't reveal anything about the dig until it has been made available to the public by MPP and others. Mike is doing a talk this evening at Bluestone Brewery, and I will no doubt hear about what is revealed! So I will do a post in due course.
I had been informed in advance of the approximate dig location, since there was apparently quite a bit of preparatory geophysics work last year while the 2016 dig was under way. It wasn't located quite where I expected -- but there are two pits, about 100m apart. The grid references are SN123357 and SN 122357. The two excavations are on the other side of the road from the Bronze Age site investigated last year, and about 200 m away from it. I'm not breaking any confidences by revealing the locations, since around 40 diggers have been at work this year, and many others have also visited the site. Everybody in the neighbourhood knows exactly where it is!
Nothing shows up in the satellite imagery for the field in which the digs are located -- and this is exactly the situation in which detailed surveying and geophysics comes into its own.
Watch this space.....
Postscript: I erroneously stated that I had met Colin Richards on the site. It was actually Adam Stanford -- apologies to both of them.

The artificial significance of Rhosyfelin and Carngoedog
As readers of this blog will know, we have often discussed sampling bias, the caveman effect, and artificial significance. Here we are again, at the end of another dig, in the MPP lecture season, where everybody prepared to listen will be told yet again that Carn Goedog and Rhosyfelin are of earth-shaking significance. They are the great bluestone quarries, now mythologized in much the same way as Stonehenge, with high pressure PR work and judiciously placed articles in the archaeological magazines. This, of course, in spite of the fact that the EVIDENCE for quarrying just does not stand up to scrutiny.
As readers will know, my thinking about Rhosyfelin is that this site has nothing whatsoever to do with either monolith extraction or with the human transport of big stones to Stonehenge -- but that it might have been used intermittently during the Mesolithic, Neolithic and Bronze Age for the fabrication of cutting or slicing implements, given the lovely sharp edges which this rhyolite gives. So in that sense, the rock might have been used opportunistically. But maybe not. Maybe the good old folks just liked being there in the woods, doing a bit of fishing, gathering berries, listening to the birds, and sheltering from the wind. Later on, some Iron Age people used this sheltered site against a craggy rock face in a wooded valley as an encampment -- maybe just over the winter months.
My thinking about Carn Goedog is that there is no prehistoric quarry there either, and that there was not actually any need for Neolithic quarrying activity on the tor, given the readily available spotted dolerite slabs, pillars and boulders scattered as glacial erratics across the Preseli landscape. If tribesmen had wanted monoliths for building into cromlechs, or for use as standing stones, they could have just picked them up, very close to the places where they were needed. People camped in the vicinity, and in that sense used the site, but bits of charcoal, ancient soils and radiocarbon dates do emphatically NOT indicate quarrying activity.
We cannot avoid talking about artificial significance. Archaeologists don't think about it often enough. We could also call it sampling bias. It is pretty clear that MPP and his colleagues have invested these two sites with significance because (a) they have decided in advance that they were Neolithic quarrying sites, and (b) simply because that is where they have dug. It is perfectly reasonable to think that if they had visited almost any sheltered craggy site in a north Pembrokeshire valley (and there are many of them) and subjected that site to the same level of scrutiny as applied to Rhosyfelin, they would have found virtually the same assortment of features -- including charcoal, hazel nuts and fireplace traces. I have made this point here:
https://brian-mountainman.blogspot.co.uk/2016/11/brynberian-gorge-paradise-for-neolithic.html
The same is true of Carn Goedog. There is nothing exceptional about it, apart from its close proximity to a droving route. If the archaeologists had dug at Carn Bica, Carn Breseb, Carn Arthur or any of the other Preseli tors, the strong probability is that they would have found traces of occupation. After all, some of these tors have prehistoric enclosures built against their rocky flanks. The diggers would have found a litter of large blocks and slabs partly buried in the turf, traces of temporary encampments, charcoal and assorted other organic and dateable materials. If they had bothered to check, they would have found a similar Pleistocene stratigraphy too.
The point is that the archaeologists have never even tried to demonstrate that these two so-called quarrying sites are exceptional or unique. There have been no control digs at any other sites with similar physical and locational characteristics -- and the sampling bias is very strong indeed.
(I have directed exactly the same sort of criticism at the geomorphologists who recently published a set of cosmogenic dates for the northern fringes of the Isles of Scilly, in support of their assumed ice limit. All of the dates were obtained from inside the assumed limit, and none of them were from outside it -- so there were no controls in the sampling programme. I still cannot believe that such an elementary error in field sampling design was made by a group of experienced researchers.......)
As noted by Darvill and Wainwright in the recent Pembrokeshire County History volume, the distribution of recorded sites is not necessarily the same as the pattern of prehistoric activity. A site does not become significant simply because it has been worked on. I agree with that, and it's a point made by other archaeologists as well. In any investigation, especially if you are seeking to demonstrate something quite exceptional (such as Neolithic monolith quarrying), you have to show that other similar places are unexceptional. Do Rhosyfelin and Carn Goedog show features that are not normal? The archaeologists have not even bothered to try to demonstrate that. That's bad science.
To come back to Hitchens's Razor, the onus is on MPP and his colleagues. Their quarrying thesis is simply rejected out of hand, until the archaeologists can come up with something more convincing.
