Swans Reflecting Elephants (1937) is a painting by the Spanish surrealist Salvador Dalí. This painting is from Dalí's Paranoiac-critical period. Painted using oil on canvas, it contains one of Dalí's famous double images. The double images were a major part of Dalí's "paranoia-critical method", which he put forward in his 1935 essay "The Conquest of the Irrational". He explained his process as a "spontaneous method of irrational understanding based upon the interpretative critical association of delirious phenomena. " Dalí used this method to bring forth the hallucinatory forms, double images and visual illusions that filled his paintings during the Thirties.
