These cylindrical objects were given to me by someone who
had no clue about them. They
had been stored inside a clay
pot that turned out, based on some research I did, to be – probably – from Pre-Columbian Central America. But there is no reason to assume that there is a contextual relationship between the
pot and these things. They may simply have been stored together by a previous owner.
The objects are small (see the penny for reference), cylindrical in form, perhaps made of fired clay (it's difficult to tell), with each cylinder apparently consisting of identically sized stacked disks that are fused together. (There is one exception to the "same size" rule - one of the cylinders tapers along its length) The tops and bottoms of each cylinder have radiating grooves. Presumably each internal disk has the same radiating lines. If you look at the cylinder with the broken “top” (upper right in the top image, near the penny), a lower disk in that cylinder has been revealed and it has those same grooves.
Each cylinder seems to have been drilled down through the center. Most of these central holes are filled – perhaps with soil rather than from intentional plugging.
I have no idea what these things are, whether they are simply old (antique) or truly ancient, and whether they are Western or otherwise. My first thought is that they might be
weights of some sort, intended to be threaded on a rod or cord to establish a particular
weight. But, really, I am clueless.
Any thoughts would be greatly appreciated.
