The kabra mask is an ongoing project by the African-Surinamese Dutch priestess of the African-Surinamese Winti religion Marian Markelo and the white Dutch artist Boris van Berkum. In this project they used 3D technology to scan (or ‘liberate’) a Yoruba (Egúngún) mask from the collection of the Dutch Africa Museum. From these scans Van Berkum produced a ‘contemporary’ ancestor mask that can be used in kabra neti (ancestor rituals). The mask was also acquired by the Amsterdam Museum, which means that the new mask now moves between the museum, commemorative ceremonies, and ancestor rituals. What role do the ancestors play in our understanding of, and dealing with colonial heritage, both in- and outside of museums?
