This week on the Post we have Gwen John (1876-1939), the subject of an exhibition at the Holburne Museum. Persephone Books has made a contribution to the sponsorship; her dedication to her art and unwillingness to compromise are attributes we recognise in many of our writers. This Self-Portrait (1902, Tate) is typical of the quiet complexity of her work in that it both reveals and conceals aspects of her personality, which is examined in the fine biography by the curator, Dr Alicia Foster.
