“[I am] God’s little artist, a seer of strange beauties, a teller of harmonies, a diligent worker,” writes Gwen John, inspired by the example of St Thérèse of Lisieux’s Little Flower. “Strange Beauties” is a retrospective of the Welsh painter’s work and personal writings currently on exhibition at the National Museum Cardiff. A rare and privileged glimpse into a life where creativity and contemplation meet.
