Debunking the Iron Age Round House

Is Prehistory is more or less bunk ?

In 1916, when archaeology was in its infancy, the industrialist Henry Ford expressed the view that History is more or less bunk, so what he would have made of Prehistory would probably have been unprintable.[1]  However, perhaps as an engineer, his concerns were elsewhere, solving the problems in the present and helping to mould the future.

In his remark, we might perceive a fundamental dichotomy of science v arts, but while this is clearly simplistic, there is a certain resonance for archaeology which sits, sometimes uncomfortably, between the two. Much of what is important, incisive and certainly less bunk in archaeology originally came from outside, from the borrowing of scientific techniques from other disciplines.  Further, in Henry Ford’s prejudice one might also perceive a divergence between practical v theoretical, or practitioners v academics; for archaeology, the latter are often from an “arts background”, and by creating the past in their own image, have divested Prehistory of its engineers, architects, builders; a prehistoric built environment fabricated almost entirely from bunk.

In the West, Archaeology is fairly new discipline, not much older than the motor car, but prehistory is not vital, and so nobody cares if you get it wrong or make it up. Unlike engineering, archaeology can be a faith based study, with objectivity, and even the evidence being secondary, what is important is belief in the narrative and its institutions.  In archaeology things can be true because people believe them, not because they are supported by the evidence. 

This is hard concept to grasp if you come from another discipline, or importantly, if you believe in the intellectual integrity of archaeology, but ideas about ancient building are a classic case in point.

36. Being on the level about Prehistoric Masons.

I am going to tell you a secret. It is older, deeper, and infinitely more real than anything dreamt up by Dan Brown. Granted, it involves masons, pyramids, and ancient secrets, all the usual suspects. But don’t be alarmed, I am a field archaeologist, and we dig through the brown stuff all the time, and dark forces tend to cross the street to avoid us.


Secrets

The use of the word secret to describe undiscovered archaeology is nothing more than as simple truism, but it serves to heighten the sense of mystery, which I am happy to invoke in a spirit of ironic, but gratuitous, hypocrisy.

30. Not going with the flow

I studied philosophy, so I know you are reading this, or at least you think you are, but I don’t know why, or whether you have done it before, and if so, how often. If you have read none of the proceeding 42,000 words, what I am about to discuss may seem a little unexpected, but I am trying not to repeat myself, and besides, those who have bravely trudged through it all deserve some reward, so I am going to give a brief glimpse of what's coming up in the next 30 posts, because from now on it’s going to get ‘interesting’. In terms of ‘why I blog’, this is my belated contribution to an interesting Internet discussion.[1] It also reflects my concerns about how I blog.
So, before we go any further, it's important we have a heart to heart about what’s going on here. We are meeting in rather unusual circumstances; my concern is what is going on in your mind when you read this, and you may be beginning to wonder about what’s going on in mine.

25. A world of Invisible Walls

How to account for things that are invisible is always tricky, as priests would no doubt testify, and in some respects archaeologists have a comparable problem to religions, in that what we are asking you to comprehend and visualise happened a long time ago. However, archaeologists, unlike priests, are happy to admit (if pushed) that what we are asking you believe is an educated guess, even if, as often the case, we have a story and we’re sticking to it with almost religious zeal.

For British prehistory the problem is that some significant pieces of the visual jigsaw have been destroyed forever, and they have become ‘archaeologically invisible’. I can tell what the woods and the trees looked like -- I have photos that must be fairly close – but the evidence for the human part, particularly the built environment where human life is played out, is somewhat sketchy.

23.Uncovered; Prehistoric Building Regulations

I want to show you something quite remarkable about prehistoric buildings that nobody ever noticed before, so you are going to be the first to know.

The previous article, which I’m sure you’ve read, looked at the roof geometry of circular buildings, and using simple theoretical models, demonstrated that large 16-17m roundhouses are probably at the technical limits of the design. We shall extend our simple model to include a theoretical longhouse, and compare the two forms to try and understand what advantages this challenging form of roof construction offers, with interesting results.

22. Iron Age Graphs; an important discovery

To be a theoretical structural archaeologist, you are going to have to understand (or at least believe in) Pythagoras, the sine rule, and pi; but there is no need to panic -- I think they still teach this to children, so it might be useful to have one to hand.


Digging holes for a living is an ideal place to hide from maths, not to mention reading and writing, but, unfortunately, Iron Age roundhouses only really make sense if you understand their geometry. Maths is important to help us model the nearly 2-dimensional evidence of prehistoric postholes, and encourages us to think 3-dimensionally about structures.

18. Credibility Crunch Hits Iron Age Building

The story of the Iron Age building boom of the later Twentieth Century starts with one man, Gerhard Bersu [left], driven to these shores by that most clichéd of archaeological plot devices, the Nazis. It is his initial speculations and concept of a roundhouse that has dominated thinking for seventy years. The concept has become an article of faith for many archaeologists, who, perhaps unwittingly, show a near religious belief in the veracity of his ideas about buildings.

However, religion and archaeology are unsatisfactory bedfellows, and anyone who has read articles 1-9 on this site will realise that I think it is time to return to the evidence and common sense, and to prick this aged speculative bubble.

11. A Strange Receding Past

The past is much further away than it used to be. The rapid change in our culture over a few generations has disconnected people from the countryside and agriculture, as well as from the skills, crafts, and materials of previous generations. The past will always be mysterious, because the vast majority of it leaves no trace and is ‘invisible’ to archaeology. These invisible bits, like buildings, we have to make up or imagine.


Increasingly, the past has become the realm of theory, abstract thought, and introspection for archaeologists operating in the wide-open spaces of our ignorance. Novel theoretical approaches are borrowed from other subjects with obscure and unfamiliar vocabularies, and these are used to conceptualise our lack of understanding. If all else fails in the strange world we are reconstructing, archaeologists pass off what we don't understand as ‘ritual’. It therefore passeth all understanding and can be used to justify all manner of absurdity.
