Femme Nue dans un Fauteuil Rouge by Pablo Picasso in the Tate Modern, London. This is a painting of Picasso’s young model, and secret mistress, Marie-Thérèse Walter. Picasso began using her as a model, before becoming her lover, while he was still married to his first wife, the Russian ballerina Olga Khokhlova. He painted the image in the first few years of their secret romantic relationship.
The painting itself was public but contains its own secret acknowledgement of the affair. It is painted with some abstraction and the face itself is rendered with some cubist-like elements. For example, there are two different planes of the face, noticeable in the nose, eyes, ears and mouth. But there is more to it. The two face planes are also distinctly divided, for example the two noses are set apart, but the faces converge together at the mouths. This is now widely regarded as Picasso, in blue and on the right, leaning in to embrace and kiss his lover, on the left.
