In early October, The Swan auction house in Tetsworth, Oxfordshire, listed several lots of human remains for sale, including skulls from west Africa and shrunken heads from South America.

They were withdrawn within a couple of days after objections were raised by representatives of the Pitt Rivers museum in Oxford and indigenous activists.

The remains included examples from the Naga people of India, the Ekoi people of present-day Nigeria and Cameroon, and other groups in the Solomon Islands, Benin, Congo, Nigeria, Amazonia and Papua New Guinea.

While the UK’s museums and education institutions increasingly have professional guidelines about the respectful treatment of human remains, those in private collections do not have any protection. Although it is difficult to legislate how people care for private collections, this case raises the question of whether human remains should still be allowed to be bought and sold at all.
