Candidate passages:
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.
As with earlier "Metamorphosis of Narcissus", "Swans Reflecting Elephants" uses the reflection in a lake to create the double image seen in the painting.
In "Metamorphosis", the reflection of Narcissus is used to mirror the shape of the hand on the right of the picture.
Here, the three swans in front of bleak, leafless trees are reflected in the lake so that the swans' heads become the elephants' heads and the trees become the bodies of the elephants.
In the background of the painting is a Catalonian landscape depicted in fiery fall colors, the brushwork creating swirls in the cliffs that surround the lake, to contrast with the stillness of the water 
Dalí produced over 1,500 paintings in his career in addition to producing illustrations for books, lithographs, designs for theatre sets and costumes, a great number of drawings, dozens of sculptures, and various other projects, including an animated short film for Disney.
He also collaborated with director Jack Bond in 1965, creating a movie titled "Dalí in New York".
Below is a chronological sample of important and representative work, as well as some notes on what Dalí did in particular years.
In Carlos Lozano's biography, "Sex, Surrealism, Dalí, and Me", produced with the collaboration of Clifford Thurlow, Lozano makes it clear that Dalí never stopped being a surrealist.
As Dalí said of himself: "the only difference between me and the surrealists is that I am a surrealist."

It holds over 1,500 works from Dalí.
Other particularly significant collections include the Reina Sofia Museum in Madrid and the Salvador Dalí Gallery in Pacific Palisades, California.
Espace Dalí in Montmartre, Paris, France, as well as the Dalí Universe in London, England, contain a large collection of his drawings and sculptures.
The unlikeliest venue for Dalí's work was the Rikers Island jail in New York City; a sketch of the Crucifixion he donated to the jail hung in the inmate dining room for 16 years before it was moved to the prison lobby for safekeeping.
Ironically, the drawing was stolen from that location in March 2003 and has not been recovered. 
The elephant is a recurring theme in the works of Dalí, first appearing in his 1944 work "Dream Caused by the Flight of a Bee Around a Pomegranate a Second Before Awakening", and also in "The Temptation of Saint Anthony" and "Swans Reflecting Elephants.
"The Elephants" differs from the other paintings in that the animals are the primary focus of the work, with a barren graduated background and lack of other content, where most of Dalí's paintings contain much detail and points of interest (for example Swans Reflecting Elephants which is somewhat better known within Dalí's repertoire than "The Elephants".
The stork-legged elephant is one of the best-known icons of Dalí's work and adorn the walls of the Dalí Museum in Spain.

<poem>I have seen such beauty as one man has seldom seen; therefore will I be grateful to die in this little room, surrounded by the forests, the great green gloom of trees my only gloom - and the sound, the sound of green.
Here amid the warmth of the rain, what might have been is resolved into the tenderness of a tall doom who says: 'You did your best, rest' - and after you the bloom of what you loved and planted still will whisper what you mean.
And the ghosts of the birds I loved, will attend me each a friend; like them shall I have flown beyond the realm of words.
You, through the trees, shall hear them, long after the end calling me beyond the river.
For the cries of birds continue, as - defended by the cortege of their wings - my soul among strange silences yet sings.
