Lukasa

Lukasa, "the long hand" (or claw), is a memory device that was created, manipulated and protected by the Bambudye, a once powerful secret society of the Luba.

Lukasa memory boards are hourglass-shaped wooden tablets that are covered with multicolored beads, shells and bits of metal, or are incised or embossed with carved symbols.

[1] The colors and configurations of beads or ideograms serve to stimulate the recollection of important people, places, things, relationships and events as court historians narrate the origins of Luba authority.

[1] Court historians known as bana balute ("men of memory") run their fingertips across the surface of a lukasa or point to its features while reciting genealogies, king lists, maps of protocol, migration stories, and the great Luba Epic, a preeminent oral narrative that records how the culture heroes, Mbidi Kiluwe and his son Kalala Ilunga, introduced royal political practices and etiquette.

[3] Culture heroes are identifiable by beads whose colors have a fan of connotations triggering remembrance of their deeds and exploits, as well as their qualities and physical appearance.

For example, Nkongolo Mwamba, the tyrannical anti-hero of the Luba charter, is always represented by a red bead, for he is the red-skinned rainbow-serpent associated with bloody violence.

Mbudye members call the twin projections sprouting along the board's outer edge the "head" and "tail" of the lukasa, zoomorphic elements that are meant to evoke the crocodile.
