Day of Archaeology – LAARC Lottery Part 3 (Registered Finds)

Here are the results from our registered finds shelf lottery

Shelf seven (suggested by Pat Hadley – thanks Pat) of our Registered finds section of the Archive is the start of a sequence of finds that were excavated before professional archaeology became existed inLondon, during the very early 1970s. At this time theMuseumofLondon’s forbearer – the Guildhall Museum– was undertaking excavations across the city. This object – a classic Roman oil lamp – was excavated on Gracechurch street in 1969.

Roman Lamp from GM69 site – and shelf number 7

This Roman lamp is known as a picture lamp, as the central ‘discus’ is decorated. It may be a Loeschecke (1919) Type IV, although difficult to tell as types are usually distinguished by the nozzle, which in this case is broken. It probably dates to the C1st AD and in particular the Boudican revolt as it was discovered in association with a major burnt strata with other C1st pottery.

A very similar lamp has also been discovered on a recent Archive volunteer project – VIP9 – although not in such a good state of preservation! Closer comparison may reveal if it was made from the same two-piece mould, as these objects were mass produced.

Shelf 342 (tweeted by our very own Adam Corsini while on holiday in Sardinia) of our Registered finds stores material from the 1980s, a point in time when archaeology withinLondonhad become highly professionalised – having a major impact on how we eventually archive material and records from excavation.

Our second lucky winner(s) are  fragmentary pieces of medieval window glass. Excavated on the site of the Royal Mint in 1986, this glass may have formed part of the medieval Abbey or Chapter House. By the C16th window glass such as this would have been found more commonly in secular buildings as opposed to religious buildings. Although extremely aesthetic, the array of colours this glass has produced are not intentional – this is actually the glass decomposing, or delaminating, as a result of being buried in the ground for hundreds of years.

Next it’s our Metal artefacts – these objects are stored separately. A dehumidified store, sealed boxes and silica gel help us maintain these objects to a high degree of preservation as they’d slowly degrade in normal room conditions. Tweet using #dayofarch or #LAARC, or message us below, a number between 1 and 628 to discover, completely at random, what that shelf holds…

 

Burials & the Last Day on Site

Who are we?

Irish Archaeology Field School is a research project and teaching dig based in the Boyne Valley in Co. Meath, Ireland. We have three sites, one at Blackfriary in Trim, a C13th Dominican abbey, one in Rossnaree, near Slane, a multi-period site, and one at Bective Abbey, a C12th Cistercian Abbey. Blackfriary is a community archaeology initiative with support from the Department of Arts, Heritage & Local Government, the local authority, and the American Institute of Archaeology Site Preservation Fund. The sites at Rossnaree and Bective are being excavated by our research partners, with funding from the Royal Irish Academy.

Blackfriary: A day in the life:

Blackfriary Abbey in Trim, Co. Meath is the site of the abbey has lain abandoned for decades and been surrounded by the expanding town. The abbey walls have largely been robbed out and the site is mostly under grass.

The current season’s research programme was designed explore the interface between the church and the cloister, which is situated immediately to the north of the church. The first month of excavation revealed lots of loose stone, evidence of the deliberate destruction of the abbey walls (the stone was likely reused elsewhere) and it is only in the last few weeks that we are finally accessing the base of the walls with foundations and stone work in situ. We are only using hand tools to excavate so there is a lot of mattocking and shovelling involved, to move a lot of material:

While the cloister wall was found reasonably quickly, the north wall of the church was heavily robbed out, and we are also reaching levels that contain f burials, both disturbed and undisturbed.

Following the dissolution of the monasteries in C16th, the abbey was no longer officially a religious centre. However people still considered the site as sacred and such sites were often used as graveyards in the centuries following. The abbey graveyard, lies to the south west of the church. There are also burials within the church. As yet we have found no conclusive diagnostic material to date them – we may have to wait for radio-carbon dates. What we do know is that we have 3 distinct burials, but we at least 6 individuals are represented by the skeletal remains recovered so far.

When a burial is uncovered, we first try to find a grave cut – that is the evidence that might remain of the grave that was dug for the burial. We then photograph it, to add to the record. The photo board notes the site registration number, the number assigned to this burial, area of the site in which it occurs, the date, and the initials of the photographer:

Burial 3 is that of a young child or infant; the remains are in reasonable condition however the bones are fragile and are particularly difficult to recover. The tools of an archaeologist include a standard trowel, and a leaf trowel for intricate or delicate work but is this instance we improvise with some wooden skewers; these are useful for precision and because the point is softer.

Excavation of material this delicate is slow work: the soil must be cleaned off each fragment of bone and stored for sieving, and each bone fragment lifted and placed in a specific box for that burial. Given the age of the individual when he or she died, the bones are small and delicate, only partially fused in some instances. Some bones are so small they may not be identifiable during excavation and may only be recovered from the sieved material. We had barely made any progress on the excavation of this burial by the end of the day so the burial has been carefully packed with bubble wrap and covered to protect it and keep it from drying out overnight.

Rossnaree – today was a day of logistics:

The dig at Rossnaree finished up today. The site is in a rapeseed field and with the harvesters on the way, the heat was on to backfill the excavations, to ensure that all the recording of the archaeological features is complete and that every detail has been noted.

Behind the scenes though is the inevitable demobilisation of the site. At Rossnaree, there was a small crew of 8-10 people for most of the four week excavation. The contents of their site cabin fitting into the back of our small van:

After loading up all the equipment, finds, samples, registers, plans and notebooks, all that’s left to do is close the gate behind us…. until next year!
