What is the value of a portrait when we don’t know who is in it?

Knowing the Unknown Sitter was an on-line anthology of texts relating to ten unidentified portraits, selected from a wealth of material found in national collections across the UK. Through the discussion of these portraits, unknownsitter.com raised questions about the nature of identity, representation, and the role of the observer in interpreting visual images. The result of an initial collaboration between myself and art historian Lara Perry (University of Brighton), the project brought together writers from a range of disciplines as well as portraits – some of which have never been published before – to explore the problem of the unknown sitter, and the value of their portraits, once identity has been lost.
