been variously interpreted. Some commentators have cautioned that Dalí's own comments on these images are not always reliable. Food Food and eating have a central place in Dalí's thoughts and work. He associated food with beauty and sex and was obsessed with the image of the female praying mantis eating her mate after copulation. Bread was a recurring image in Dalí's art, from his early work The Basket of Bread to later public performances such as in 1958 when he gave a lecture in Paris using a 12-meter-long baguette an illustrative prop. He saw bread as "the elementary basis of continuity" and "sacred subsistence". The egg is another common Dalínian image. He connects the egg to the prenatal and intrauterine, thus using it to symbolize hope and love. It appears in The Great Masturbator, The Metamorphosis of Narcissus and many other works. There are also giant sculptures of eggs in various locations at Dalí's house in Port Lligat as well as at the Dalí Theatre-Museum in Figueres. Both Dalí and his father enjoyed eating sea urchins, freshly caught in the sea near Cadaqués. The radial symmetry of the sea urchin fascinated Dalí, and he adapted its form to many artworks. Other foods also appear throughout his work. The famous "melting watches" that appear in The Persistence of Memory suggest Einstein's theory that time is relative and not fixed. Dalí later claimed that the idea for clocks functioning symbolically in this way came to him when he was contemplating Camembert cheese. Animals The rhinoceros and rhinoceros horn shapes began to proliferate in Dalí's work from the mid-1950s. According to Dalí, the rhinoceros horn signifies divine geometry because it grows in a logarithmic spiral. He linked the rhinoceros to themes of chastity and to the Virgin Mary. However, he also used it as an obvious phallic symbol as in Young Virgin Auto-Sodomized by the Horns of Her Own Chastity. Various other animals appear throughout Dalí's work: rotting donkeys and ants have been interpreted as pointing to death, decay, and sexual desire; the snail as connected to the human head (he saw a snail on a bicycle outside Freud's house when he first met Sigmund Freud); and locusts as a symbol of waste and fear. The elephant is also a recurring image in his work; for example, Dream Caused by the Flight of a Bee Around a Pomegranate a Second Before Awakening. The
