Introduction

In a recent instalment of Digging for Britain, Alice Roberts stirred the archaeological debate by asserting that the Dorset Chalk Giant at Cerne Abbas had Saxon origins rather than prehistoric roots. This added a layer of intrigue, especially from a landscape archaeology perspective. At first glance, the giant’s features appear to echo a much earlier connection, reminiscent of other chalk figures found elsewhere in Britain, where their placement within the landscape suggests a deeper, functional context.

Curiosity led to a closer look at the methods used to date this iconic figure, and the findings raise several important questions. While the programme presents a clear and confident conclusion, a deeper inspection reveals fundamental issues and omissions that call into question its reliability. This is not just about one site but about broader methodological problems in archaeology, particularly the uncritical acceptance of dating approaches that underpin many historical assumptions.

The primary technique involved excavating four small trenches and penetrating approximately 1 m into the topsoil to extract samples. The underlying assumption is that the surface beneath the chalk line represents the original ground level and therefore provides the latest possible date for the figure’s creation. While the theory itself is not unreasonable, the reliance on just four sampling points raises serious concerns about the representativeness of the results.

To fully support such a method, variations across the entire area beneath the figure would need to be taken into account. Limited sampling introduces the risk of missing key variations in the soil and sediment, which could significantly alter the dating outcome. Scientific investigation depends on comprehensive data, and without it, conclusions remain open to question.

In addition, the programme does not fully explore alternative interpretations or the potential impact of environmental processes on the site. This becomes particularly important when considering evidence from other studies, in which larger datasets have shown a wide range of dates from similar contexts. In one such case, forty-two samples produced dates ranging from the ninth millennium BCE through to the historic period, yet only a subset was used to support the final interpretation. This raises an obvious question about the selection and exclusion of data.

The reliance on a very small number of samples for OSL dating introduces a substantial margin of uncertainty. Across a large area such as this, variation is expected. With such limited data, the resulting data range cannot be considered definitive. The methodology, including how samples are collected and interpreted, does not meet the level of precision expected in modern scientific analysis.

There is also a fundamental geological factor that appears to have been overlooked. The site sits on a steep slope, where soil creep is an ongoing process. Even at a conservative rate, soil can move approximately one metre over a thousand years. This means that materials such as snails and sediments beneath the figure are not necessarily in their original position. Over long periods, they can be displaced downslope, disconnecting them from the original context to which they were dated.

The physical construction of the figure itself also raises questions. The current form sits within topsoil rather than being cut directly into the underlying chalk bedrock. From a practical perspective, a prehistoric construction would be more logically cut into solid chalk to ensure durability and reduce maintenance needs. The fact that the figure requires ongoing upkeep suggests a different history, potentially involving phases of covering and reworking.

Historical accounts suggest that subsequent activity may have altered or preserved the figure, raising the possibility that what is visible today is not the original construction. This opens the question of whether an earlier figure existed beneath the current one, potentially modified or replaced at a later date.

The landscape context adds further complexity. The figure is positioned at the edge of a range of hills rather than at its highest point, and its full form is clearly visible only from elevated viewpoints. This challenges the idea of it functioning as a simple ground-level marker and instead suggests that its placement may relate to a broader landscape system that is no longer immediately visible.

When all of these factors are considered together, the conclusion presented in the programme appears far less certain than initially suggested. The evidence does not point to a simple, single-phase construction, but rather to a more complex history influenced by geological processes, environmental change, and possible later modification.

Archaeological interpretation must remain grounded in robust, testable methods. When conclusions rely on limited data, untested assumptions, or incomplete consideration of environmental factors, they risk presenting certainty where uncertainty remains.

The Dorset Chalk Giant is not a straightforward case. It is a reminder that understanding the past requires not just data, but careful evaluation of how that data is gathered, interpreted, and applied.

The next stage of analysis will examine the wider landscape using LiDAR data, with the aim of reconstructing how this site functioned in a prehistoric environment and what it may originally have represented.

Part 2

Now, in this second part, our focus shifts to the professionalism of archaeologists involved in such endeavours and, by extension, the broader state of the archaeological profession in the 21st century. A critical lens is turned towards the National Trust’s excavation efforts, particularly the four trenches dedicated to OSL dating. Despite the extensive timeframe of over two years for this undertaking, the conspicuous absence of an official report raises concerns about transparency and the ability of other knowledgeable individuals to conduct scrutiny. This delay in producing and sharing findings with the wider community calls into question the efficiency and accessibility of archaeological information.

The quality of documentation further comes into question, as hand-drawn cross-sections, seemingly rushed and lacking the meticulous detail expected in rigorous scientific practices, were presented. This not only reveals an apparent ‘back of an envelope’ approach but also underscores a profound oversight by the experts. Despite having two years for scrutiny and examination, critical questions were left unexplored, a shortcoming magnified by the collaboration with the BBC for the televised program.

Cerne Abbas

The absence of a comprehensive and timely report, coupled with the apparent lack of attention to detail in documentation, casts doubt on the thoroughness and professionalism of the archaeological efforts surrounding Cerne Abbas. The urgency to present findings to the media and create a documentary may have compromised the meticulousness required in archaeological endeavours.

This prompts a broader reflection on the state of the archaeological profession itself. The slow pace of report publication, potential gaps in expertise, and a seeming reluctance to subject findings to rigorous scrutiny raise concerns about the discipline’s agility and accountability in contemporary times.

The deficiencies in the excavation process around Cerne Abbas become more apparent when we scrutinise the placement of the trenches and the sampling locations. The hand-drawn illustrations (which I consider ‘outdated’ in an era of affordable, widely available 3D high-definition cameras) indicate that samples were taken from the topsoil just above the chalk bedrock. However, a photograph reveals a more accurate location at the bottom of the topsoil, near the chalk bedrock, leading to the conclusion that it is Saxon.

Poor Conclusions

A critical oversight emerges when we consider the implications of the Saxon date. If accurate, the absence of topsoil dating back thousands of years raises intriguing questions. Three plausible scenarios are explored: the deliberate removal of soil before the construction of Cerne Abbas, the initial absence of soil, or inaccuracies in OSL dating.

Option one, soil removal, implies an intention to obliterate what was originally present, raising logistical questions about the necessity for such an extensive process compared to the simplicity of laying new lines on existing chalk.

Option two speculates on the absence of soil due to something atop the bedrock, a theory we will delve into further.

Option three questions the accuracy of OSL dates, which, if proven, could cast doubt on the entire OSL science.

Option two gains credence when exploring the Post-Glacial Hypothesis, which is grounded in the notion of elevated sea levels in prehistoric times. LiDAR imagery of the site reveals a landscape shaped by Mesolithic waters, with identified natural harbours and Neolithic camps indicating the higher historical river levels. Archaeological findings, including tools and earthworks, support the hypothesis that the river running parallel to the figure was significantly higher during the Neolithic period.

Prehistoric Landscape

This scenario accounts for approximately 7,000 years with no topsoil in the figure. Examining the bedrock reveals signs of extensive water weathering, consistent with chalk erosion over thousands of years. The excavation report and photographs reveal broken chalk at the base of the topsoil, indicating water-induced erosion and redeposition. The darkened appearance, a result of drying after being broken and re-laid on top, mirrors the common impact of water on solid chalk.

Further evidence points to Post-Glacial Flooding and a Neolithic origin of the figure, which strategically marks the entrance to the harbour. LiDAR maps suggest a man balancing a load on his shoulders or head, potentially representing a trading centre surrounded by quarries and mining pits.

The intricacies of Cerne Abbas, when viewed through the lens of geological processes and archaeological evidence, unfold a narrative of ancient landscapes shaped by water, a figure emerging from millennia of erosion, and a Neolithic trading hub leaving its mark on the chalky canvas of history.

Long Man of Wilmington

NB. The findings at The Long Man of Wilmington by Prof. Martin Bell show very similar findings and geology as Cerne Abbas –

“Our method was to machine cut a trench at the base of the slope to look at the sediment sequence, then carefully hand excavate an adjoining strip, recording in three dimensions the positions of all artefacts, no matter how modern, in order to date each layer.

At the base of our trench, there were chalk meltwater muds from a time of rapid physical weathering at the end of the last Ice Age. Above these were bowl-shaped features, perhaps tree-throw pits, because they contained land snails from woodland habitats, indicating that this part of the slope had been wooded earlier in the Postglacial. They also contained some flint flakes, so they could be archaeological features.

Over this was a buried soil. Ed Rhodes, formerly of the Research Laboratory for Archaeology at Oxford, now of the Australian National University, has used OSL to date this soil to the mid-2nd millennium BC. The snails show that by this time, the landscape was open. Later in the Bronze Age, the soil was buried by more soil derived from cultivation at the base of the slope. Snails show that the escarpment above was grassland. Many sites on the South Downs show evidence for quite extensive Bronze Age soil erosion. Bronze Age and Neolithic pottery and flints from the basal soil and the colluvium indicate that a settlement was nearby.”

They called the broken chalk we saw in these excavations ‘chalk meltwater muds’, and he is correct, but this kind of deposit can only be produced by thousands of years of water erosion, not a couple of hundred, and his OSL dates confirm this, as just above this level is an OSL date of 2,000 BCE. We have 8,000 years of topsoil missing as the site, like Carne Abbass, was covered with river water, creating another natural harbour – and would you believe it – it also has a Neolithic.

Author’s Biography

Robert John Langdon, a polymathic luminary, emerges as a writer, historian, and eminent specialist in LiDAR Landscape Archaeology.

His intellectual voyage has been interwoven with stints as an astute scrutineer in government and grand corporate bastions, a tapestry spanning British Telecommunications, Cable and Wireless, British Gas, and the esteemed University of London.

A decade hence, Robert’s transition into retirement unfurled a chapter of insatiable curiosity. This phase saw him immerse himself in Politics, Archaeology, Philosophy, and the enigmatic realm of Quantum Mechanics. His academic odyssey traversed the venerable corridors of knowledge hubs such as the Museum of London, University College London, Birkbeck College, The City Literature Institute, and Chichester University.

In the symphony of his life, Robert is a custodian of three progeny and a pair of cherished grandchildren. His sanctuary lies ensconced in the embrace of West Wales, where he inhabits an isolated cottage, its windows framing a vista of the boundless sea – a retreat from the scrutinising gaze of Her Majesty’s Revenue and Customs, an amiable clandestinity in the lap of nature.

Exploring Prehistoric Britain: A Journey Through Time

My blog delves into the fascinating mysteries of prehistoric Britain, challenging conventional narratives and offering fresh perspectives grounded in cutting-edge research, particularly LiDAR technology. I invite you to explore some key areas of my research. For example, the Wansdyke, often cited as a defensive structure, is re-examined in light of new evidence. I’ve presented my findings in my blog post Wansdyke: A British Frontier Wall – ‘Debunked’, and a Wansdyke LiDAR Flyover video further visualises my conclusions.

My work also often challenges established archaeological dogma. I argue that many sites, such as Hambledon Hill, commonly identified as Iron Age hillforts, are not what they seem. My posts Lidar Investigation Hambledon Hill – NOT an ‘Iron Age Fort’ and Unmasking the “Iron Age Hillfort” Myth explore these ideas in detail and offer an alternative view. Similarly, sites like Cissbury Ring and White Sheet Camp receive re-evaluations based on LiDAR analysis in my posts “Lidar Investigation Cissbury Ring through time” and “Lidar Investigation White Sheet Camp,“ revealing fascinating insights into their true purpose. I have also examined South Cadbury Castle, often linked to the mythical Camelot56.

My research also extends to ancient water management, including the role of canals and other linear earthworks. I have discussed the true origins of Car Dyke in multiple posts, including Car Dyke – ABC News Podcast and Lidar Investigation Car Dyke – North Section, which suggest a Mesolithic origin 2357. I also explore the misidentification of Roman aqueducts, as seen in my posts on the Great Chesters (Roman) Aqueduct. My research has also been greatly informed by my post-glacial flooding hypothesis, which has helped explain landscape transformations over time. I have discussed this hypothesis in several posts, including AI now supports my Post-Glacial Flooding Hypothesis and Exploring Britain’s Flooded Past: A Personal Journey

Finally, my blog also investigates prehistoric burial practices, as seen in Prehistoric Burial Practices of Britain and explores the mystery of Pillow Mounds, often mistaken for medieval rabbit warrens, but with a potential link to Bronze Age cremation in my posts: Pillow Mounds: A Bronze Age Legacy of Cremation? and The Mystery of Pillow Mounds: Are They Really Medieval Rabbit Warrens?. My research also includes astronomical insights into ancient sites, for example, in Rediscovering the Winter Solstice: The Original Winter Festival. I also review new information about the construction of Stonehenge in The Stonehenge Enigma.
