Catharine MacLeod is Curator of Seventeenth-Century Portraits at the National Portrait Gallery. She contributed to 100 Writers, a publication that brings together portraits of writers from various periods who have made an important contribution to British society and culture. Inspired by the collaboration between Hay Castle Trust, the National Portrait Gallery and Hay Festival, Catharine explores the relationship between writing and portraiture with art historian and newly appointed Director of Hay Castle, Tom True.
