A Koi board is a stylised carved representation of ancestors. It’s often made out of wood, as it’s believed each tree has a spirit and the koi is designed with the spirits within.

In this episode, we hear from the ancestral spirit of a Koi board which once occupied the spiritual centre of its community in the Purari Delta region of Papua New Guinea. It tells the story of its creation, function and current state of mind having been displaced for over a century.

On this sonic museum tour, Hanna Adan, with the assistance of experts, explores the fascinating spiritual landscape of the object’s origin, the role of Christian missionaries in colonisation and asks - what is the Museum’s duty towards objects of spiritual significance when the cultures of the source communities have drastically changed?
