Painted circa 1939, Bird Superior, Portrait of Max Ernst is a rare biographical masterpiece in which Carrington depicts her great love, Max Ernst. Leonora Carrington, a Mexican painter of English birth, studied under Amédée Ozenfant and would go on to become one of Mexico's most important Surrealist artists. When she met Ernst in 1937, the two began a passionate love affair that is immortalized in the present work.

In this mysterious double portrait, Carrington depicts Ernst as a hermit standing on a glacial formation. Carrington incorporates herself into the painting via metamorphosis. A white horse, her avatar, is shrouded in icicles in the background of the composition and in the lantern held by Ernst. This portrayal of Ernst derives from alchemical lore and recalls the image of a Hermit from a tarot card. Like the Hermit Tarot, Ernst symbolizes introspection and isolation.

In a recent exhibition catalogue of Carrington’s work, Sarah Glennie wrote about this double portrait, inspired by the symbolism in Carrington's writing: “In her short story The Bird Superior Max Ernst, published in the special edition of the American journal View (April 1942), and dedicated to Ernst, Carrington wrote of the Bird Superior (Ernst) and a horse (Carrington) becoming one in the presence of an alchemical fire and cauldron.  Their union was symbolized by Ernst transforming into a bird who unties the horse from the fire so that together they are freed to escape through the war winds which leap out of the pot like smoke, like hair, like wind.  Love is here represented by the philosopher’s stone, but the cauldron (symbolizing rebirth), the horse (symbolizing escape) and the bird (symbolizing renewal) tend to all evoke a quintessentially Celtic goddess iconography” (quoted in Leonora Carrington (exhibition catalogue), op. cit., p. 142).
