The conservation team are celebrating this week as we have completed work on a beautiful and exciting project. Conservation of the stunning finds excavated from Bognor Regis by Thames Valley Archaeological Services in 2008 has come to fruition. The items form part of an unusual burial assemblage along with an iron ‘bed’ frame and sword and are thought to originate from the late Bronze Age/ early Iron Age.
The finds first came to us in the unassuming form of a large soil block, this was too large to x-ray at our labs so was transported to a local hospital where x-rays revealed a large amount of intricate metal latticework and a helmet.
The soil block was carefully excavated, layer by layer, revealing the spectacular nature of the copper alloy items held within. The helmet and latticework were extremely fragmented and fragile, the helmet was split in half and part of the lattice was adhered to the helmet with corrosion products.
Every year the History Centre hosts work experience students from Year 10 to Higher Education. Alex, a year 10 student from Malmesbury School describes what he got up to during his week:
Recently I have had work experience at the Wiltshire and Swindon History Centre in Chippenham. On my first day I got shown around the strongrooms which they have lots of original documents, records and certificate etc. I actually saw King Henry VIII’s marriage deed with Jane Seymour. After that I saw Archives Conservation and got told how they restore letters, papers and maps, I also saw a small piece of Napoleon’s hair, and a really nice photo album. I also had a look at a newspaper by Swindon Advertiser in 1918 and 1919 which was really interesting to look at all the different stories they had at that moment in time.
On the second day for the morning I was copying and pasting wills onto a disc for a researcher. Then I got an original document from the strongroom and I had to find the names and occupations of people, where they lived and the year, but it was sometimes really hard to find some people because the writing was really hard to read and some documents did not give names. After lunch I went into the object conservation lab and saw a sole from a roman shoe in the wet room with a freeze dryer, also I went into an x-ray room. After that I saw a very old ceramic pot that had been damaged by a badger when it was digging, the people in the lab were trying to put it back together. After that I did community history and I had an introduction to the Wiltshire Community History website and was able to look at all the different parishes that they have written information about.
In the archaeology service most new archaeological discoveries tend to be through our advice on planning applications. If a proposed development has the potential to impact heritage assets and in particular those with archaeological interest (as referred to in the National Planning Policy Framework), then we advise planning officers that a programme of archaeological investigation needs to be carried out in order to determine the significance of heritage assets affected by the proposals. Since I joined the archaeology service in August 2012 there have been some really exciting discoveries through development management, an overwhelming amount dating to the Romano British period. To name some of the top sites over the last few years that date to this period, we've had a Roman villa in Devizes, a roadside settlement near Beanacre, a high status farmstead outside Chippenham, two farmsteads on the outskirts of Trowbridge...the list goes on. In fact I have been surprised at just the amount of activity going on during this period in our county. Maybe it's not surprising considering we have some major Roman roads running through (see map below) including the main routes from London to Bath; from Silchester to Dorchester (Port Way); from Lincoln to Exeter (Fosse Way) and from Winchester to Charterhouse (Mendips). The two towns of Cunetio (Mildenhall) and Sorviodunum (Salisbury) lay at important junctions of the strategic road network and other towns of Durocornovium (Wanborough) and Verlucio (Calne) are also known to lie along the road network.
Many of you no doubt have read recently in the newspapers or heard on the radio that there has been a major new Roman discovery in the Deverills. We got a call from Luke Irwin who explained that whilst constructing an electricity cable to one of his outbuildings his workmen stumbled upon some kind of tiled floor surface and the tiles appeared to be quite small and colourful. He ordered the workmen to stop digging and that is when he contacted us. Of course my initial reaction was that of incredible excitement tempered by the realism, "what are the chances", people often tend to over exaggerate the significance of archaeological discoveries in their gardens. Despite my cynicism I quickly arranged to visit the site the following day with the County Archaeologist, Melanie Pomeroy-Kellinger. Upon our arrival Luke explained that one of his workmen was interested in archaeology so had meticulously cleaned the floor. When we peered down the cable trench both our mouths must have dropped open and I think we both said at the same time "I don't believe it, you have got a Roman mosaic!!!” There was no arguing with the clearly distinctive Roman mosaic pattern, a common geometric border pattern known as guilloche.
You may remember the image of a group of ceramic sherds from one of our previous blog posts. Following reconstruction of the vessel we now have true understanding of the magnificence of the objects found. Watch a time-lapse video showing elements of the reconstruction of the vessel.
Conservation treatment involved a task like a jigsaw puzzle without a picture. The size, shape and colours of the sherds were used to determine their original location within the urn. Due to the uneven firing of the vessel and areas of burning caused by hot ashes being placed inside the vessel some areas were easier to piece together than others.
When the collared urn was originally manufactured ceramic technology was in its infancy with the kilns used never reaching the temperature required to permanently set the clay in position. During the time the vessel was in the ground, moisture from the surrounding earth also weakened the under-fired structure. This effect, on top of the unconventional excavation method, has meant that the overall shape of the vessel has become distorted.
Before reconstruction the edges of each fragment were strengthened by allowing a weak adhesive to be drawn into the rough surface to hold the loose and sometimes crumbling structure together. The adhesive is well used in conservation and has been developed and tested to ensure that it is long-term stable meaning it will not degrade causing damage to the original fragments of the vessel.
A stronger concentration of the same adhesive was used to adhere the fragments in position, small strips weak masking tape were used to hold the fragments in position as they dried. As the vessel was so large the reconstruction had to be undertaken in stages to ensure each level of fragments were securely in position and ready to support those placed on top.
The clocks have gone forward, days are getting longer, the sun (hopefully) shining brighter and the museums in Wiltshire that have been closed over the Winter are staring to open their doors to the public.
But don’t be fooled – these museums have not been hibernating, inactive over the last few months. Hard working volunteers have been busy behind the scenes doing all the work required to look after the collections and create new, vibrant and interesting exhibitions.
Enjoying the displays as a visitor it is can be easy to overlook all the time and effort that goes into producing them and keeping the museum ship shape. This includes a wide range of activities such as keeping the building tidy, making sure historic collections are well cared for, documenting and cataloguing objects to appropriate standards, researching local history, writing labels and telling stories, selecting the most suitable items for display and talking to members of the local community – to name just a few!
Bradford on Avon Museum recently re-opened following their mid-winter closure, which was spent cleaning, tidying and repainting. Work carried out in the gallery includes new interpretation and displays of the Museum’s collection including road and shop signs from the town. Visitors now also have the opportunity to view pieces of plaster from a Roman Bath Complex, excavated in Bradford-upon-Avon in 1976. Not all of the changes at the Museum are immediately visible however. In addition to what’s been happening front of house, work has also been carried out with the collections in storage to make the most of the available space.
There has also been a hive of activity in Aldbourne and I was very pleased to attend the opening of Aldbourne Heritage Centre in the village over the Easter weekend.
The Heritage Centre tells the story of the village of Aldbourne through stories, photographs and historic collections collected from local residents. A large crowd of people gathered outside the Centre to witness the proceedings.
On the day the ribbon was cut by archaeologist, broadcaster and Time Team regular, Phil Harding. He spoke to the assembled visitors about how important the Heritage Centre is to the village and how it can help the community remember its history and discover more about its roots.
This roughly square feature, with further squares on the corners, was first seen in the geophysical results when this housing site was first considered for development. At that point, no-one was quite sure what it was. Although a Civil War date was considered, it was also possible that this feature was associated with the WW2 features that surrounded it.
We had a look at it in the trenched evaluation, but didn’t get much more information, and so an excavation was required as part of the planning permission. This took place in 2015 and the initial post-excavation works are well under way. The excavation demonstrated that the structure was indeed large and square with square ‘turrets’ on the corner. Its outline was made up of a ditch cut into the chalk.
There were also the remains of a small building with flint footings, which can be seen in the photo above in the centre of the group of archaeologists.
