The Cheval Glass (c.1913-1915). Francis Campbell Boileau Cadell (Scottish, 1883-1937). Oil on canvas. Rather than a portrait in the traditional sense, The Cheval Glass can be described as an arrangement; the figure of the woman and her reflection are elements within the composition as much as they are the subject of it. The painting incorporates brilliant touches of pure pigment, applied with marvellous effect to provide accents of colour which delicately balance the composition.
