Martin Carruthers continues the exciting story of Day Nine at The Cairns….
Hi folks, Martin here yet again. Not meaning to bore you by doing the blog again two days running but I thought I’d better describe today’s findings. What I have to share with you, however, is anything but boring! It’s been an amazing day on site.
If you’ve been following the blog thus far you’ll know from yesterday’s piece that we began to excavate the so-called ‘well’ that lies deeply under the floor of the broch. This subterranean structure is reached by a set of steep stone steps that curve down, slightly spiralling in a counter-clockwise direction. There’s a very sticky silty fill down there. It’s very wet and claggy and we’ve considered that it might hold out the promise of organic preservation. Today that promise has come true!
Within the partially rock-cut chamber, underneath the very fine upper grey silt deposit we uncovered a darker deposit, still very wet, but with a more compact consistency, and, I have to say, a quite a distinctive smell!
This morning we got the first hint of organic preservation from this dark deposit in the form of what appeared to be grass fibres, some of which even appeared as if they might be woven! There were also pieces of tree bark present. This was sufficiently stunning, and we were just contemplating the significance of this over morning tea break, but this was nothing to the shock of what emerged after the break. I was working in the well myself carefully examining the ‘dark deposit’, and noticed a strange solid curving object beginning to appear amidst the silt. Unbelievably, it was a wooden bowl…
I was astonished to see this very dark, very smooth object begin to appear more clearly as a vessel. The bowl is in several large chunks, but all in the correct relationship to each other showing that the vessel was complete, and it was clearly lying upright with the rim upwards. In form, the thing has a lovely out-swinging (or everted) rim just like a contemporary Iron Age pot. The bowl is round-bottomed like some Middle Iron Age ceramic vessels too. Within the curve of the rim I could see that there was further organic preservation – a mass of plant material. Startlingly, a second wooden object became apparent lying near to the wooden bowl, but closer to the bottom step of the staircase leading into the chamber. This time it was a long piece of round-wood about 20 centimetres long with a pronounced carved head at one end and a sort of carved ledge under the ‘head’. The object very closely resembles a modern wooden tent peg!
Before the end of the day we were able to lift the peg and the wooden vessel and safely pack it all up in protective layers and significant amounts of its own silty matrix within a plastic crate. The whole thing will have to be sent off to conservators to stabilise the object and prevent any deterioration of the precious wooden object. In the meantime we have not yet reached the bottom of the chamber. It was quite clear that in lifting the wooden bowl there was more organic material beneath, what seemed like a thick mass of plant fibres, perhaps the bowl was resting on a mat of some sort! Only a little time will tell as we continue to excavate this important feature!
Meanwhile in other parts of the site some great progress has also been made. Over in area M/Q Bobby’s team have yet again been revealing more wall lines. By the end of today they now have uncovered three sides of the building that lies just outside the broch entrance (Structure O). This looks like a large imposing building, with very well built walls utilising substantial blocks of sandstone, just the sort of grandeur that would be expected of one of the premier buildings within the broch-village complex. Also, in the same part of the trench a whopping whalebone vertebra has been uncovered and it has been carved, and pierced to provide handle holes, we think, and utilised as a chopping board with many serious chopping scars revealed on the surface.
In the south extension Linda’s team have been continuing to work away at the ditch fills, and, nearby, Angus has been revealing even more of Structure J, a village building tucked into the lee of the broch and its construction terrace.
Finally for this round up, back to the broch interior and Therese has been recording the slab floor in the Western quadrant and then she began to lift the shattered remains of the late hearth base slab. Underneath lay more burnt material and edges of stones that suggest an earlier hearth remains to be fully investigated. In the Southeast quadrant of the broch Ross continued to grid-excavate the beautiful ashy floor horizons with their riot of black and vivid red colours.
Gary and Paul have begun to remove the fill (masses of rubble) from a huge pit set in the floor of the broch and we’ll hopefully get to see what this very deep set feature is all about over the next few days- possibly a sub-floor tank that has been partly robbed out for stone and then filled in or something more enigmatic? We’ll see…
Well tomorrow’s another day and we’ll keep you posted on what emerges!
