When looking at the disc brooch, it's interesting to note that while each quadrant appear generally symmetrical, the branches that cross over or under are not consistent. A branch in one quadrant crossing over another actually crosses under that same branch in another quadrant. It's certainly intentional, but I wonder if perhaps it conveys some meaning... or perhaps the artisan just thought it'd be neat. It seems like a lot of work though to have no significance. Intriguing.
