It looks like a paired-string instrument, but all the strings look to be the same diameter, so it's not a 12-string guitar. I think lutes have five string pairs, but I don't know if they are all the same diameter. Hammer dulcimers have single strings that double back, creating an effective double string. But neither lutes nor hammer dulcimers are bowed, I think. Some viols have paired strings, but I think their strings are of different diameters.
Just thinking out loud, as it were. I'm probably no closer here than I was with the burnt wire and the cobwebs.
