El Dorado Metaphor

In the mythology of the Muisca today, El Dorado (Mnya) represents the energy contained in the trinity of Chiminigagua, which constitutes the creative power of everything that exists. Chiminigagua is, along with Bachué, Cuza, Chibchachum, Bochica, and Nemcatacoa, one of the creators of the universe.
Meanwhile, the name of El Dorado came to be used metaphorically of any place where wealth could be rapidly acquired. It was given to El Dorado County, California, and to towns and cities in various states. It has also been anglicized to the single word Eldorado.
In literature, frequent allusion is made to the legend, perhaps the best-known references being those in Milton's Paradise Lost (Book xi. 408-411) and in Voltaire's Candide (chs. 18, 19). "Eldorado" was the title and subject of a four-verse poem by Edgar Allan Poe. In the 1966 John Wayne film El Dorado, most of Poe's poem is recited by the character nicknamed Mississippi [1] El Dorado is also referenced in Joseph Conrad's novella Heart of Darkness. Within Conrad's work, the Eldorado Exploring Expedition journeys into the jungles of Africa in search of conquest and treasure, only to meet an untimely demise.
El Dorado is also sometimes used as a metaphor to represent an ultimate prize or "Holy Grail" that one might spend one's life seeking. It could represent true love, heaven, happiness, or success. It is used sometimes as a figure of speech to represent something much sought after that may not even exist, or at least may not ever be found. Such use is evident in Poe's poem "El Dorado". In this context, El Dorado bears similarity to other myths such as the Fountain of Youth, Shangri-la, and to some extent the term "white whale" which refers to Captain Ahab's obsession in the book Moby-Dick. The disillusionment side of the ideal quest metaphor may be represented by Helldorado, a satirical nickname given to Tombstone by a tardy miner who complained that many of his profession had traveled far to find El Dorado, only to wind up washing dishes in restaurants.
