Fractures of the Whole: A Depiction of the shamanic universe on Kača drums brought by J.J. Sederholm from Siberia in 1917

This paper is a brief description of two drums brought by Finnish geologist Jacob Johannes Sederholm from the expedition to Siberia in 1917. Research on drums, based on the ethnographical sources and museum collections, was done to identify provenance of the studied objects. Two drums, brought by Sederholm, have not previously been described in the scholarly work. Both of them are in the private collections of J. J. Sederholm’s grandchildren.
