Sheila: Portrait of an Unknown Artist is an intimate examination of the life of SHEILA DENNING, one of the many women painters who worked in Britain in the twentieth century, but whose work received little or no attention from the art establishment. Sheila was the author's mother. Born in 1920 to an Anglo-Irish family, Sheila lost her favourite brother in WWII. In the grief-filled years that followed, and despite a dispiriting experience at Camberwell School of Art, she painted a series of compelling self portraits. Once married, Sheila allowed the needs of her clay-worker husband to set the agenda and her career floundered. But in the late 1960s, newly separated and a lone parent, she produced a stream of extraordinary portraits of people in her immediate circle. These were brave, honest paintings, the work of an artist who looked deeply into the faces of her sitters. Working within the genre of memoir, Thornhill interrogates Sheila's paintings with her own painter's eyes in an attempt to understand who her mother was. She dramatizes incidents and conversations remembered from childhood; she quotes from Sheila's letters, poems and an incomplete autobiography. The narrative is driven forward by the author's deep love for her mother, her need to disentangle herself from an overly close mother-daughter relationship and her desire to fathom what got in the way of Sheila thriving as an artist. The book is fully illustrated with 22 colour plates and 8 black and white plates.
