Cooking up Chronology

Pottery is one of the most commonly recovered artefacts from archaeological sites, but accurate radiocarbon-dating of these objects has proven extremely challenging. A team of scientists at Bristol University, led by Prof Richard Evershed, and associated research colleagues from various organisations including CA, have developed a technique to accurately and directly radiocarbon-date pottery. This technique targets the fatty residues from food trapped within the porous fabrics of pottery vessels used to prepare, cook and consume food. The process involves using preparative gas chromatography to extract palmitic and stearic fatty acids from pottery. The residue is then radiocarbon-dated using accelerator mass spectrometry.

Focusing on pottery of Neolithic date and from sites of known age that have already been dated by scientific means, such as the Sweet Track (Somerset),  this new technique will allow the direct dating of individual vessels, the construction of refined typochronologies and the mapping of pottery distributions and direction of any geographical spread {trade/exchange}. In particular, the technique can be used where other organic material that is routinely used for scientific dating  simply has not survived. The new technique features in the online edition of Nature (Volume 580).

Discovering Dannicus

Dannicus is the Cotswold Archaeology logo – but who is he?

When Cotswold Archaeological Trust was created in 1989, a logo was required for the new charity. One idea was a feline, to match our abbreviation CAT, but in the end we chose instead one of the iconic images of Roman Cirencester, our hometown. In the 1830s, workmen digging in Cirencester discovered two inscribed tombstones of Roman auxiliary cavalrymen – both are now in Corinium Museum. The tombstones are similar in that they both depict a mounted soldier riding over a fallen enemy, although they are not identical. The finer carved tombstone is a monument to a soldier named Genialis, which shows the soldier looking to the side. The other tombstone is a memorial to a soldier named Dannicus, this time depicting the man looking directly at the viewer, and for that reason Dannicus was chosen as our emblem (despite the depiction of his steed as something akin to a pantomime horse!).

So who was Dannicus? The inscription on the tombstone tells us that he was a trooper in the regiment called the ala Indiana, came from the area around Basel in Switzerland and served in the army for 16 years. Dannicus’ regiment has nothing to do with India; it was named after its first commander, Julius Indus, who raised his own regiment in Trier, Germany, to help suppress a revolt by local tribesmen. The unit then moved to southern Germany, and that is where the local boy Dannicus would have been recruited. Dannicus could have come to Britain in AD 43 with the invading Roman army, or else in the aftermath of the rebellion of queen Boudica (the Boadicea of modern legend) in AD 61 to replace units destroyed in the uprising.

Dannicus died sometime after AD 70 and in his will he instructed his two executors, Fulvius Natalis and Flavius Bitucus to erect a tombstone to his memory. That they did, and it lay in the ground for almost 1900 years before seeing the light of day once again. Dannicus lived an amazing life in the 1st century AD. What stories he must have recounted, and how extraordinary that after a boyhood in Switzerland he came to be an enduring symbol of a town in far off England, and the logo for all of us at CA.

Cotswold Archaeology and COVID-19

Cotswold Archaeology fully understands and accepts its responsibilities for the safety and well-being of our staff, clients and others during the national health emergency brought about by the onset of the COVID-19 virus. We have worked hard over the last month or so to ensure that our operations accord with evolving Government guidance and have developed a suite of COVID-19 Health & Safety policies and procedures. Most recently we revised our risk assessments to align fully with the guidance set out in Working Safely During Coronavirus. You can view our COVID-19 office and site risk assessments. This has allowed us to adhere to the Government’s directive that construction sites should remain open, where it is safe to do so. Through this vigorous management effort we have been able to work on an increasing number of archaeological field projects throughout the country and anticipate shortly that we will be able to deploy around three quarters of our field teams to site.

All five of our offices remain open for business, but are naturally closed to visitors. The majority of our office staff are working remotely from home, but have full connectivity and are able to respond to customer communications and new project enquiries. If you have an enquiry on a potential new project please contact us in the usual way, using email or mobile telephone numbers. On current projects we continue to adapt to changing customer requirements and methods of working.

Inevitably all of our public engagements are postponed for now, but we do hope to reschedule these when it is safe and practicable to do so.

Cotswold Archaeology will react accordingly as the Government unwinds its lockdown restrictions over the coming months and we will update this notice as the situation changes.

‘Long-lost’ medieval friary uncovered in Gloucester

Recent evaluation trenching by Cotswold Archaeology on the site of the former multi-storey car park on Bruton Way, Gloucester, has identified the remains of the city’s medieval Whitefriars Friary for the first time. The site was being investigated on behalf of Reef Group, which is working with Gloucester City Council to bring forward a £85m scheme to regenerate the King’s Quarter area of the city. This includes ‘The Forum’ – a new social and digital campus for the South West.

Archaeologists have long suspected that the Bruton Way bus station and car park was the site of Gloucester Whitefriars, a 13th-century friary founded by the Carmelites, one of the Roman Catholic Church’s four great mendicant (living by charity) orders. Andrew Armstrong, City Archaeologist at Gloucester City Council, said: “For around three hundred years, Whitefriars played an active part in Gloucester and produced some notable friars, including Nicholas Cantelow (or Cantilupe) in the 15th century. It’s very exciting to finally reveal the exact location of this ‘long-lost’ friary. Seeing and documenting this site will serve to underline, and recognise, the place of the friary in the city’s history.”

Whitefriars was one of several important religious houses in medieval Gloucester along with Llanthony Priory, the Blackfriars and the Greyfriars. Whitefriars’ place in the city’s history has tended to be overlooked because of the lack of identifiable remains. It owned most of the land between what is now Station Road and Bruton Way, which is shown in some historic maps as ‘Friars Ground’. Whilst a variety of sources suggest the friary was located at the western end of this land, next to Market Parade, it has not been possible to confirm the precise location of the friary until now.

The investigations suggest there were at least four large medieval buildings at the site. These buildings were either built of stone or had stone footings, with some of the walls measuring a metre wide. The team has also found the remains of tiled and mortared floors, and part of a medieval drain. Importantly, some of the larger walls are aligned east-west – a typical feature for a medieval ecclesiastical building.

The Carmelites in Gloucester

Historic records suggest that Whitefriars was founded in Gloucester around 1268 with grants from Queen Eleanor (the wife of Henry III), and members of the Giffard and Berkeley families. Henry III is known to have given eight oaks towards the building of the friary. His son Edward I also supported the friary, which during its heyday supported around 30 friars in the community. The Carmelites were so called because they traced their origins to a community of hermits on Mount Carmel. By the middle of the 13th century they were an established mendicant order popular in much of Western Europe. They were often referred to as ‘White Friars’ because of their white cloaks.

The Gloucester Whitefriars, like every other monastery in England, was supressed by 1538 on the orders of Henry VIII. By that time there were only three friars left, and the friary was in financial difficulty. By the late 16th century little was left of the friary building complex. One building, known as the friars’ barn, was used in the defence of the city during the English Civil War. Gloucester had sided with Parliament during the war and was famously besieged by Royalist forces in August 1643. The friars’ barn, being made of stone, was used as a fortification by the defenders of the city but was demolished some years later.

The Forum

The Forum forms a key component of the plan to regenerate the Kings Quarter area of Gloucester. Esther Croft, Development Director at Reef, said: “Working in partnership with the City Council, our aim is to deliver The Forum with the least possible impact on these important archaeological remains. We expect, as the development moves forward, that further archaeological investigations will be needed, hopefully improving our understanding of this intriguing site. We look forward to sharing the full results of this dig, and any future archaeological work, with the people of Gloucester.”

RAF Stoke Holy Cross Radar Station

In 2019, CA was commissioned to record part of a reasonably well-preserved ‘Chain Home’ early warning radar station, located just south of Norwich.

Chain Home was a pioneering network of radar stations constructed prior to, and during, the Second World War. An experiment in 1935 proved conclusively that it was possible to detect aircraft by radio. The experiment worked by ‘illuminating’ the sky with radio waves whereby sufficient energy would be reflected from an aircraft to permit detection on the ground via a receiver. After further research, funding was provided for the construction of a ‘chain’ of early warning stations along the east coast of Britain using the new radar technology. These stations became the first radar to be organised into a complete air defence system used in wartime operations.

A key component of each station was a pair of ‘buried reserves’, which comprised underground bunkers and associated surface features containing a set of duplicated backup equipment, intended for use if the principal transmitting or receiving sites were attacked and put out of action.

Our task was to record the visible, above ground remains of the ‘transmitting’ buried reserve at Stoke Holy Cross Radar Station, which required the identification of many non-descript concrete features scattered amongst the encroaching vegetation. Luckily, Chain Home stations all follow a fairly standard form and further research allowed the identification of most of these features. These included ventilation shafts (see photo below left), a holdfort for a Bofors anti-aircraft gun, concrete plinths for the steel transmitting tower, and heavy concrete access hatches -(see photo below right) for the underground reserve itself, including their steel rollers and rails. Although the underground reserve is presently unsafe to enter, the positions of the above ground features were such that the layout of the reserve could be reliably determined by comparing the site with other, better preserved examples at stations around the country.

Ultimately, the Chain Home network was supplanted by superior technology, but the important role that these stations played during the Second World War, and the increasing scarcity of their most significant features, is being recognised through appropriate statutory protection.
