Boli

Source term: Rhombe

boli (pl. boliw): a Bamana power object, built up by repeated sacrificial offerings so as to accumulate and control nyama, the life force.

Layer on layer of sacrificial blood has all but swallowed this blade. A boli is made that way on purpose: a form built up by repeated offerings until the crust accumulates and directs nyama, the life force that acts on the world, and the original contours vanish under it. This one began as thirty-two centimetres of whirled wood, and the Bamana men's societies of Ndomo, Korè and Komo kept it. What the offerings gave it in power they took from it in voice. Komo’s night hyena also manifests Faaro, the great serpent of creation, while initiates dance its zigzag: the blood-fed blade belongs to that serpent-linked society.
