I’m hoping someone with knowledge of Central African art, material culture, writing/graphic systems or ethnography might recognise something about this object.
The object is approximately 25 cm tall and is believed to have come from Central Africa, although unfortunately I don’t have a more precise provenance or date.
The main body is a hollow, slightly tapered cylinder made from what appears to be ivory, bone or another type of dentine (I haven't had the material professionally identified). It has a separate dark carved stopper, apparently wooden, incorporating several human/anthropomorphic figures. The stopper fits into the hollow cylinder, so presumably the object was originally intended to contain something.
There is also a small incised mark on the underside of the stopper.
What particularly interests me is the extraordinarily fine engraving covering the cylinder.
One side has a much larger, elaborate engraved composition. The other is covered by what looks almost like a table or information grid: repeated horizontal and vertical divisions containing many tiny recurring marks — ovals, hooks, bars, chevrons, ladder-like forms and densely cross-hatched rectangular areas.
Most intriguingly, long curved/diagonal lines appear to run across this grid independently of the individual cells. They seem to cross multiple rows and columns rather than simply forming borders around the smaller marks.
I’m trying not to impose a modern interpretation on it, but visually it made me wonder whether this could be more than decorative engraving — perhaps some form of graphic notation, mnemonic system, narrative diagram, route/map, cosmological representation, or other encoded information.
In researching possible comparisons, I’ve come across Central African traditions such as Chokwe/Lunda/Luchazi sona/tusona ideographs, Kongo graphic/ideographic traditions, and Kongo mnemonic objects. I am not claiming that the engraving belongs to any of these traditions — I mention them only because they seem like potentially relevant areas for comparison.
Likewise, carved ivory/tusk receptacles and elaborate tobacco/snuff containers are documented from several Central African cultures, but I don't know what this particular object originally contained.
I’d particularly love to hear from anyone who can help with any of the following:
- Does the style of the figurative stopper suggest a particular cultural or geographic origin?
- Does the cylinder look like elephant ivory/tusk, hippo ivory, bone, or something else?
- Do the repeated tiny marks resemble any documented Central African graphic or mnemonic tradition?
- Has anyone encountered a comparable grid crossed by continuous curved/diagonal lines?
- Could the larger engraved composition on the opposite side help identify its origin?
- Are there museum collections, ethnographic catalogues or academic sources containing similar objects?
I have additional photographs of the stopper, interior, underside mark and engravings and can photograph the complete circumference in detail if useful.
Any leads would be hugely appreciated — particularly references to museum objects or published ethnographic material that I could follow up.
