Unfinished paintings can be seen in many of the world's great collections, including that of the National Gallery of Scotland: they fascinate the viewer and raise intriguing questions. What circumstances left them incomplete? What do they tell us about the ways that painters worked? How do we define 'finish', and when did an artist consider a work to be finished? These and other questions will be considered by David Bomford, in an exploration of the non-finito from the Renaissance to the 20th century. The Watson Gordon Lecture Series: The Watson Gordon Lectures, established in 2006, typify the long-standing collaboration between the University of Edinburgh and the National Galleries of Scotland. Each lecture is by a leading scholar and reveals new research on a focused topic. The lectures are delivered and published annually, and now number eight titles in the series.
