Background: Salvador Domingo Felipe Jacinto Dali i Domenech, Marquis of Dali de Pubol (11 May 1904 - 23 January 1989), known professionally as Salvador Dali ( Catalan: [s@lb@'do d@'li]; Spanish: [salba'dor da'li]), was a prominent Spanish surrealist born in Figueres, Catalonia, Spain. Dali was a skilled draftsman, best known for the striking and bizarre images in his surrealist work. His painterly skills are often attributed to the influence of Renaissance masters.
Context: Dali employed extensive symbolism in his work. For instance, the hallmark "melting watches" that first appear in The Persistence of Memory suggest Einstein's theory that time is relative and not fixed. The idea for clocks functioning symbolically in this way came to Dali when he was staring at a runny piece of Camembert cheese on a hot August day. The elephant is also a recurring image in Dali's works. It appeared in his 1944 work Dream Caused by the Flight of a Bee Around a Pomegranate a Second Before Awakening. The elephants, inspired by Gian Lorenzo Bernini's sculpture base in Rome of an elephant carrying an ancient obelisk, are portrayed "with long, multijointed, almost invisible legs of desire" along with obelisks on their backs. Coupled with the image of their brittle legs, these encumbrances, noted for their phallic overtones, create a sense of phantom reality. "The elephant is a distortion in space", one analysis explains, "its spindly legs contrasting the idea of weightlessness with structure." "I am painting pictures which make me die for joy, I am creating with an absolute naturalness, without the slightest aesthetic concern, I am making things that inspire me with a profound emotion and I am trying to paint them honestly." --Salvador Dali, in Dawn Ades, Dali and Surrealism. The egg is another common Daliesque image. He connects the egg to the prenatal and intrauterine, thus using it to symbolize hope and love; it appears in The Great Masturbator and The Metamorphosis of Narcissus. The Metamorphosis of Narcissus also symbolized death and petrification. There are also giant sculptures of eggs in various locations at Dali's house in Port Lligat as well as at the Dali Theatre and Museum in Figueres. Various other animals appear throughout his work as well: ants point to death, decay, and immense sexual desire; the snail is connected to the human head (he saw a snail on a bicycle outside Freud's house when he first met Sigmund Freud); and locusts are a symbol of waste and fear. Both Dali and his father enjoyed eating sea urchins, freshly caught in the sea near Cadaques. The radial symmetry of the sea urchin fascinated Dali, and he adapted its form to many art works. Other foods also appear throughout his work.
Question: How did Dali come up with these symbolism ideas?
Answer:

Background: Cronin was born in Cardross, Dunbartonshire, Scotland, the only child of a Protestant mother, Jessie Cronin (nee Montgomerie), and a Catholic father, Patrick Cronin. Cronin often wrote of young men from similarly mixed backgrounds. His paternal grandparents had emigrated from County Armagh, Ireland, and become glass and china merchants in Alexandria. Owen Cronin, his grandfather, had had his surname changed from Cronague in 1870.
Context: The Citadel (1937), a tale of a mining company doctor's struggle to balance scientific integrity with social obligations, helped to incite the establishment of the National Health Service (NHS) in the United Kingdom by exposing the inequity and incompetence of medical practice at the time. In the novel Cronin advocated a free public health service in order to defeat the wiles of those doctors who "raised guinea-snatching and the bamboozling of patients to an art form." Dr Cronin and Aneurin Bevan had both worked at the Tredegar Cottage Hospital in Wales, which served as one of the bases for the NHS. The author quickly made enemies in the medical profession, and there was a concerted effort by one group of specialists to get The Citadel banned. Cronin's novel, which was the highest-selling book ever published by Victor Gollancz, informed the public about corruption within the medical system, planting a seed that eventually led to reform. Not only were the author's pioneering ideas instrumental in the creation of the NHS, but the historian Raphael Samuel asserted in 1995 that the popularity of Cronin's novels played a substantial role in the Labour Party's landslide victory in 1945. By contrast, according to one of Cronin's biographers, Alan Davies, the book's reception was mixed. A few of the more vociferous medical practitioners of the day took exception to one of its many messages: that a few well-heeled doctors in fashionable practices were ripping off their equally well-off patients. Some pointed to the lack of balance between criticism and praise for hard-working doctors. The majority accepted it for what it was, a topical novel. The press attempted to incite passions within the profession in an attempt to sell copy, while Victor Gollancz followed suit in an attempt to promote the book, all overlooking the fact that it was a work of fiction, not a scientific piece of research, and not autobiographical. In the United States The Citadel won the National Book Award, Favorite Fiction of 1937, voted by members of the American Booksellers Association. According to a Gallup poll conducted in 1939, The Citadel was voted the most interesting book readers had ever read.
