August 2020 - The 'Big Dig' Revisited


Back to Introduction and Contents


After spending much of the month of July in preparation the sun shone on us on the morning of Monday August 3rd. when friends and colleagues, both old and new gathered for the first week of the Hanwell Big Dig. It really paid off having had a machine to remove so much of the topsoil as it meant that everyone, and this was especially important for the new volunteers, were straight into serious archaeology. After a guided tour and a visit to the finds department to see Hanwell's greatest hits as far as discoveries were concerned, we had most people spaced out along the eastern side of the wall to the central island uncovering rubble and more. Meanwhile Verna and Sarah began the long delayed task of drawing the elevation of the wall on the north east side of the island. After lunch we had a bit of a swap round with work beginning again down in the lower levels of silt to the south. All over by 4.00 p.m. but a great start to the fortnight.



August20     August20
Everyone starts work cleaning rubble from the partially collapsed wall, social spacing looking good.




August20
Verna and Sarah battle with lines and tapes to get set up for their drawing marathon.




August20     August20
Back on the wall Nina and Evie have been promoted to clean along the top whilst Ian and John have been sent into the pit where they discover... wonderful things.




August20     August20
Sarah, excused from measuring, is sent into lonely exile to recover a rather fine, although partially broken wine bottle, only a highly qualified museum professional is allowed to carry this kind of stuff around.



Day two saw the arrival of Toby and Nathan and as well as more rubble clearance we also made great progress on planning and elevation drawing, the high light of the day, however, was the discovery of a remarkably fine base and stem of a  glass goblet, all admirably handled by the now re-activated finds department..



August20
The start of the day, Evie draws pots whilst Maurice, Ian and Nina dig silt, someone has to do it.



August20     August20
Nina is drawn away to act as measurer in chief as we draw the elevation of the south wall whilst on their first day back Nathan and Toby polish rubble.




August20     August20
However, the main attraction was Maurice's discovery of a marvelous glass goblet base and stem, a tricky bit of excavation prior to lifting... and here it is.




August20
Up at the finds department it is cleaned up and further research reveals a very close parallel from Martin Biddle's excavations at Nonsuch Palace, specifically in their catalogue of Venetian and Facon de Venise glass number 43, described in these terms:

   ' Fragmentary wine or beer glass, greyish colourless glass with overall iridescent weathering.  Flat based conical bowl with rigaree-trail round basal angle, mounted directly on a hollow spherical ribbed knop which is in turn joined by a merese to a rising foot, below which is a small neat pontil-scar. Probably Venetian, about 1670'  R.J. Charleston... couldn't have put it better myself. Certainly the dating is spot on.



August20     August20
]Meanwhile Ian excavates a length of wood, current best guesses include a distaff, or a shillelagh or a hurling stick, and we have visitors.



Day three didn't have so much drama but we were delighted to welcome Jasmine and Emilia as new volunteers. Otherwise it was a day spent clearing silt, washing finds, polishing rubble and drawing walls. All of it important stuff but a little low on the excitement quotient.




August201August201August201
Toby and Peter heading north in their quest for the wall, Ian and Nathan still down in the depths and Chris, Emilia and Jasmine are stuck in the middle polishing rubble... a normal day on site.




Day four saw us extending our reach to the north and attempting to finish off the last bit of clearance of the lowest levels of silt along the south west side of the site. As part of this I took it upon myself to clear the remnants of a small baulk left opposite the corner of the south end of the west side. This had been left in place as a temporary dam whilst the water levels were high but when I started to lift the remaining rubble a very unremarkable looking chunk turned into an extraordinary piece of architecture once prized from the mud. The evening saw a very agreeable gathering to share... out of doors and with appropriate social distancing of course... a BBQ.




August20     August20
Nina and Evie take on some serious spadework whilst Maurice, Chelsea and Nathan try to see the back of the last of the really sticky stuff.




August20     August20
Nina and Evie receive their reward, it's time to draw some wall.  Back in the mud Chelsea uncovers probably the largest piece of window glass seen so far, even if it is in several pieces




August20
Such was the excitement at the time that we didn't get any photos of the lifting of this piece so here it is cleaned and on display up in the courtyard of the Coach House.




Day five and we said some goodbyes and some hellos but it was very much a day of  tying up loose ends and reorganizing equipment prior to  Sarah and I departing for Croft Castle the following week.


August20     August20
Social time over the mid-morning coffee break then back to cleaning rubble.




August20     August20
Verna and Nina draw more walls whilst Chelsea contemplates finds before catching her train.




August20
... and at the end of a busy week we have a serious collection of finds trays to process.... next week.



Week two had Verna in the driving seat with Ian as second in command, as we welcomed back some old hands from the previous week and said 'hello' to Lucy another new recruit. Not so much photographic coverage but suffice it to say that an amazing job was dome by everyone in practically finishing the onerous task of exposing the 'sea of rubble' or 009 as it is more prosaically known and washing serious quantities of finds. This week's celebration was a very fine tea laid on for us on Thursday by our ever gracious hosts Rowena and Christopher.



August20     August20
Some more interesting architecture starting to emerge amongst the rubble as the last of it is exposed.




August20     August20
Wall cleaning is an important task before completing the planning and still the finds keep emerging from the silt, bits of wine bottle this time.



Poor weather and general exhaustion meant that after two weeks of full on digging we took a bit of a break for house-keeping, including taking down, washing, drying and storing away until the next 'big dig' one of the gazebos. We did squeeze in a couple more days on site before the end of the month with some serious digging underway before storm Francis hit us with heavy rain and strong winds and that was it until September!

Washing down the mud-stained gazebo a key archaeological skill.

Peter and Chris trim section edges whilst Rupert and Kate get to grips with rubble polishing.    John explores a notably large chunk of wall plaster while Verna contemplates drawing the next metre square of rubble and then...

The storm hit and we...

... retreated to the finds department to get some washing, sorting and labeling done.
