In Greek mythology, Narcissus (/nɑːrˈsɪsəs/; Ancient Greek: Νάρκισσος, romanized: Nárkissos) was a hunter from Thespiae in Boeotia (alternatively Mimas or modern day Karaburun, Izmir) who was known for his beauty which was noticed by all, regardless of gender. According to the best known version of the story, by Ovid, Narcissus rejected all advances, eventually falling in love with a reflection in a pool of water, tragically not realizing its similarity, entranced by it. In some versions he beat his breast purple in agony at being kept apart from this reflected love, and in his place sprouted a flower bearing his name.
 The character of Narcissus is the origin of the term narcissism, a self-centered personality style. This quality in extreme contributes to the definition of narcissistic personality disorder, a psychiatric condition marked by grandiosity, excessive need for attention and admiration, and an inability to empathize.
 The name is of Greek etymology. According to R. S. P. Beekes, "[t]he suffixes [-ισσος] clearly points to a Pre-Greek word." The word narcissus has come to be used for the daffodil, but there is no clarity on whether the flower is named for the myth or the myth for the flower, or if there is any true connection at all. Pliny the Elder wrote that the plant was named for its fragrance (ναρκάω narkao, "I grow numb"), not the mythological character.
 In some versions, Narcissus was the son of the river god Cephissus and nymph Liriope, while Nonnus instead has him as the son of the lunar goddess Selene and her mortal lover Endymion.
 Several versions of the myth have survived from ancient sources, one from a Greek traveler and geographer of the second century AD named Pausanias and a more popular one by Ovid, published before 8 AD, found in Book 3 of his Metamorphoses. This is the story of Echo and Narcissus, a story within another story, indicating that is in fact a poetics. The framing in Ovid shows the story is a test of the prophetic abilities of Tiresias, an individual who had been both a man and a woman, and whose sight was taken from him during a contest between Juno and Jove. He had taken Jove’s side and Juno, angered, blinded him. In its place, Jove gave him future sight, or prophecy. The prophecy which made Tiresias’ name for him was the story of Echo and Narcissus.
 After being “ravaged” by the river god Cephissus, the nymph Liriope gave birth to Narcissus “beautiful even as a child."  As was apparently custom, she consulted the seer Tiresias about the boy’s future, who predicted that the boy would live a long life only if he never “came to know himself”. During his 16th year, after getting lost while hunting with friends, Narcissus came to be followed by a nymph Echo. 
 Echo, an Oread (mountain nymph), like Tiresias, had a sensory ability altered after an argument between Juno and Jove. Echo had kept Juno “occupied” with gossip while Jove had an affair behind her back. So she took from Echo her agency in speech; Echo was, thereafter, never able to speak unless it was to repeat the last few words of those she heard. Echo had deceived using gossip; she would be condemned to be only that from then on.
 Meanwhile, Echo spied Narcissus, separated from his hunting friends, and she become immediately infatuated, following him, waiting for him to speak so her feelings might be heard. Narcissus sensed he was being followed and shouted "Who's there?” Echo repeated "Who's there?” After a few rounds of this, in which Narcissus’ confusion and frustrations mounts, Echo came close enough so that she was revealed, and attempted to embrace him. Horrified he stepped back and told her to “keep her chains". Echo was heartbroken and she wasted away, losing her body amidst lonely glens, until nothing but her chaste verbal ability remained of her. 
 Nemesis, the goddess of revenge, heard the pleas of a young man who had fallen for Narcissus but was ignored and cursed him; Nemesis listened, proclaiming that Narcissus would never be able to be loved by the one he fell in love with. 
 Thus, in the same, long, lost journey narrated by Ovid, after spurning Echo and the young man, Narcissus was getting thirsty. He finds a pool of water which Ovid tells us no animal had ever approached. Leaning down to drink, Narcissus sees a reflection. Ovid, inhabiting Narcissus' mindset, describes what he sees as being as beautiful as a marble statue. Narcissus did not realize it was his own reflection and fell deeply in love with it, as if it were someone else; in this way, Tiresias’ prophecy came true in the same instance as did Nemesis’ curse. Unable to leave the allure of this image, Narcissus eventually realized that his love could not be reciprocated and he melted away from the fire of passion burning inside him, eventually turning into a gold and white flower.
 An earlier version ascribed to the poet Parthenius of Nicaea, composed around 50 BC, was discovered in 2004 by Dr Benjamin Henry among the Oxyrhynchus papyri at Oxford. Again, like in Ovid, Narcissus lost his will to live and committed suicide. A version by Conon, a contemporary of Ovid, also ends in suicide (Narrations, 24). In it, a young man named Ameinias fell in love with Narcissus, who had already spurned his male suitors. Narcissus also spurned him and gave him a sword. Ameinias committed suicide at Narcissus's doorstep. He had prayed to the gods to give Narcissus a lesson for all the pain he provoked. Narcissus walked by a pool of water and decided to drink some. He saw his reflection, became entranced by it, and killed himself because he could not have his object of desire. A century later the travel writer Pausanias recorded a novel variant of the story, in which Narcissus falls in love with his twin sister rather than himself. In all versions, his body disappears and all that is left is a narcissus flower.
 The myth of Narcissus has inspired artists for at least two thousand years, even before the Roman poet Ovid featured a version in book III of his Metamorphoses. This was followed in more recent centuries by other poets (e.g. Keats and Alfred Edward Housman) and painters (Caravaggio, Poussin, Turner, Dalí (see Metamorphosis of Narcissus), and Waterhouse).
 In Stendhal's novel Le Rouge et le Noir (1830), there is a classic narcissist in the character of Mathilde. Says Prince Korasoff to Julien Sorel, the protagonist, with respect to his beloved girl:
 She looks at herself instead of looking at you, and so doesn't know you.
 During the two or three little outbursts of passion she has allowed herself in your favor, she has, by a great effort of imagination, seen in you the hero of her dreams, and not yourself as you really are.
 
(Page 401, 1953 Penguin Edition, trans. Margaret R.B. Shaw). The myth had a decided influence on English Victorian homoerotic culture, via André Gide's study of the myth, Le Traité du Narcisse ('The Treatise of the Narcissus', 1891), and the only novel by Oscar Wilde, The Picture of Dorian Gray.
 Paulo Coelho's The Alchemist also starts with a story about Narcissus, found (we are told) by the alchemist in a book brought by someone in the caravan. The alchemist's (and Coelho's) source was very probably Hesketh Pearson's The Life of Oscar Wilde (1946) in which this story is recorded (Penguin edition, p. 217) as one of Wilde's inspired inventions. This version of the Narcissus story is based on Wilde's "The Disciple" from his "Poems in Prose (Wilde) ".
 Author and poet Rainer Maria Rilke visits the character and symbolism of Narcissus in several of his poems.
 Seamus Heaney references Narcissus in his poem "Personal Helicon" from his first collection "Death of a Naturalist": To stare, big-eyed Narcissus, into some spring
Is beneath all adult dignity. In Rick Riordan's Heroes of Olympus series, Narcissus appears as a minor antagonist in the third book The Mark of Athena.
 William Faulkner's character "Narcissa" in Sanctuary, sister of Horace Benbow, was also named after Narcissus. Throughout the novel, she allows the arrogant, pompous pressures of high-class society to overrule the unconditional love that she should have for her brother.
 Hermann Hesse's character "Narcissus" in "Narcissus and Goldmund" shares several of mythical Narcissus' traits, although his narcissism is based on his intellect rather than his physical beauty.
 A. E. Housman refers to the 'Greek Lad', Narcissus, in his poem "Look not in my Eyes" from A Shropshire Lad set to music by several English composers including George Butterworth. At the end of the poem stands a jonquil, a variety of daffodil, Narcissus jonquilla, which like Narcissus looks sadly down into the water.
 Herman Melville references the myth of Narcissus in his novel Moby-Dick, in which Ishmael explains the myth as "the key to it all," referring to the greater theme of finding the essence of Truth through the physical world.
 On Sophia de Mello Breyner Andresen's A Fada Oriana, the eponymous protagonist is punished with mortality for abandoning her duties in order to stare at herself in the surface of a river.
 Joseph Conrad's novel The Nigger of the 'Narcissus' features a merchant ship named Narcissus. An incident involving the ship, and the difficult decisions made by the crew, explore themes involving self-interest vs. altruism and humanitarianism.
 Naomi Iizuka's play Polaroid Stories, a contemporary rewrite of the Orpheus and Eurydice myth, features Narcissus as a character. In the play he is portrayed as a self obsessed, and drug addicted young man who was raised on the streets. He is alluded to being a member of the LGBT+ community and mentions his sexual endeavours with older men, some ending with the death of these men due to drug overdoses. He is accompanied by the character Echo, whom he continuously spurns.
 Scottish-Canadian animator Norman McLaren finished his career with a short film named Narcissus, re-telling the Greek legend through ballet.
 Narcissus appears in the Disney adaptation of Hercules. In the film, he is portrayed as an Olympian god with purple skin.
 In the film Bab'Aziz, directed by Nacer Khemir, a Narcissus like character was portrayed by an ancient prince who sat by a pond for days after days and looked at the reflection of his own soul. He was referred to as 'The prince who contemplated his soul'.
 Narcissus has been a subject for many painters such as Caravaggio, Poussin, Turner, Dalí, Waterhouse, Carpioni, Lagrenée, and Roos.
 Sculptors such as Paul Dubois, John Gibson, Henri-Léon Gréber, Benvenuto Cellini and Hubert Netzer have sculpted Narcissus.
