You’d never guess from her art how passionate Gwen John was

‘Dearest Gwen,’ writes Celia Paul, born 1959, to Gwen John, died 1939, ‘I know this letter to you is an artifice. I know you are dead and that I’m alive… But I do feel mysteriously connected to you.’ And well she might, because the parallels between the lives of the two painters are legion. To take the most obvious: both were students at the Slade, both had relationships with much older artists and both came to be seen, for a time at least, through the prism of their association with men. Gwen John was the older sister of the once more famous Augustus and model and lover of the French sculptor Auguste Rodin; Celia Paul, the lover, model and mother of a son of the painter Lucian Freud.

Paul stepped into the limelight three years ago with her first book, Self-portrait, a devastatingly honest account of a painter’s life. The current volume is written around a series of 26 letters she has written to Gwen John, and is at once diary and confessional, biography and autobiography and something between the two.
