Spirit drum `nkonko di Lemba´ Bakongo - possibly Woyo / Schlitztrommel Bakongo Kongo
Marc Leo Felix explained: „This diviner´s gong is not old, it is ancient and could be even older than we think, it might be centuries old – not only because the wood is totally demineralized and dessicated but also because of the numerous overlapping layers of patina which, on an object of this kind take literally centuries to build up. The strictness of the design is also witness to its antiquity."

„A nganga Lemba (priest of Lemba) would play such a nkonko while performing his role as grand initiator in the Lemba rite. It is said that the number of nkonko at a given ceremony depends on how many persons are being initiated. Each initiate is accompanied by his personal initiator, and none can enter the Lemba circle without a nkonko to strike."
Excerpt from: Robert Farris Thompson - Body and Voice: Kongo figurative musical instruments.
"Numerous texts speak of the ancestors or mythic heroes being "in" the drums, or of them "speaking" through the drums, or of Lemba being "drummed up" by the Lemba father or chief priest The drum of Lemba whether nkonzi, nkonko or ngoma was frequently copied in miniature, the cavity being filled with plant substance (the "powers" above) to retain or conjure a spell (ndokolo).
Such a process of representing a representation, or metaphorizing a metaphor, may permissibly be termed fetishization. The miniature drums of Lemba were either hung on statues, or carried about on one's body as a charm. On Woyo pot-lids illustrating proverbs, Lemba was represented by the drum motif."
