It's interesting that the schist disc may represent some kind of mechanical part, yet the carving of the stone replica is a technological mystery unto itself. The rub, however, is that same people (of the era anyways) who carved the disc also carved these other things (among countless other fine stone vessels and the like). Hmmm. Weird.
