Did you draw the belt in Paint? Good job
kostana oplata refleksnog luka- Spring, I think it's a weapon! Luk i strela!
I was thinking last night, almost without my will, "what's that 'koštalo'? That can't be in civil engineering, it has to do with medicine or biology, it became a bone-looking thing, stiff and frail, laying there in the ground for hundreds of years... that must be a thing, not a construction or some part of it.... no, that's not a building, it doesn't make sense...."
First, it's hard to have some planks survived hundreds of years in the ground or elsewhere, metals and bones, for example can. They probably didn't have sheathing panels then, their ways of building and buildings were very different, cleaver in their own way, but not that sophisticated to use panels in this context.
"Oplata" is not oplata we think, it's a term used in description of some other constructions - for instance, of a weapon. "Koštana oplata" - a (bone, organic) reinforcement of a wooden longbow, maybe.
I don't know, but somehow I'm sure it has nothing to do with architecture...
