Bronze Age! Yes, that's a bit before my usual time span, but I'm getting more and more fascinated by these very early textiles. First of all, I wonder how much of a difference the fibre makes - would you be able to tell, from the touch of the finished cloth, whether the fibre has 15 micron 0r 22, or 30?
I'm also fascinated by an oddness in the weaving technique. The surviving blankets were huge - the one from Egtved was 190 by 258 cm. That is a width that would be hard to handle for a single weaver. Add to that the fact that there are weft crossings in the fabric - there's just one weft per shed, but it's not the same one all the way through. Weft A comes from the left, weft B from the right, and at some point roughly in the middle, both go to the surface of the fabric and cross each other. Then weft A continues its journey to the right in the next shed, while weft b goes to the left, and they turn normally at the selvedge. This sometimes occurs with three weft threads instead of two.
Thanks to the wonderful image database of the Danish National Museum, you can have a look at this weft crossing thing in the
Trindhoj blanket here. There's some crossings in the area left of the hole - you can download the image and then go hunting for these oddities with your image viewer of choice.
My suspicion is that two (or even three) weavers worked together on these superwide fabrics, and the crossings are where the spools or sticks or whatever they used changed hands from one weaver to the other.
This is really fascinating, and I'd love to try this out. The only tiny issue is that this requires a superwide loom (with the corresponding large number of weights, and large amounts of yarn), and some other people willing to have a go at weaving... Though a bit of testing might be possible with a loom and fabric with less width, to get an idea of the method, at least.
