Lukasa is a traditional memory board used by the Luba people of the Democratic Republic of the Congo. It is made from wood and often decorated with beads, shells, and other materials. The board serves as a mnemonic device, helping users recall important historical events, genealogies, and cultural stories. The design of a Lukasa is unique, with raised patterns that represent different concepts or narratives. Users manipulate the board with their fingers, allowing them to engage with the information in a tactile way. This practice highlights the importance of oral tradition and memory in Luba culture.
