A 19th century Vili mask from Congo meets a 21th century masked conservator in Berlin – now that’s an image worth sharing! Jonathan Fine, African art curator at Berlin’s Ethnologisches Museum, recently posted this great picture on his twitter account. It shows a conservator examining a Vili mask (III.C.8098a) to figure out what kind of conservation it needs to be displayed. He’s wearing a mask because many objects in the museum’s storage were treated with pesticides years ago. Its residues tend to collect on the surfaces and if these are dusty, the pesticides can get into the air easily. For objects that have not recently had dust removed (especially things with feathers where dust is easily trapped), conservators need to wear masks and protective gear. One of the first steps in preparing objects for exhibition in the Humboldt Forum in 2019 is to treat them to remove surface dust.
ps Robert Visser, who collected the Berlin mask between 1882 and 1898, made the below field-photo showing a ndunga mask “at work”. On the pedestal before the kneeling man, one can also spot a power figure (intriguingly slightly out of focus as if it did not want to be photographed). There are only a few known examples of this type of mask: the Museum of Ethnography in Leiden and the World Museum Rotterdam each have two; another example can be found in the Museu Nacional de Etnologia in Lisbon.
