The Last Unicorn is a fantasy novel written by Peter S. Beagle and published in 1968. It has sold more than five million copies worldwide since its original publication, and has been translated into at least twenty languages. The third-person narrative centers on a unicorn who, believing she is the last of her kind in the world, sets off on a journey to discover what has happened to the others. She encounters a host of diverse characters as her journey progresses, each of them bringing her closer to her goal.
It took Beagle "close to two years" to write The Last Unicorn, and he states that "it was hard every step of the way". Beagle came up with the idea for the novel in 1962 while on an "artistic retreat" in Berkshire Hills after Viking Press rejected his novel, The Mirror Kingdom. He stated that though the idea for the novel was "just suddenly there", he also said that he had "read tons of fantasy and mythology" from childhood, and that his mother told him that he had shared a story about unicorns during a visit to one of the elementary school classes she taught. He also mentioned that he loved the book The Colt from Moon Mountain by Dorothy Lathrop (a story about a unicorn in Kansas) as a child, and that Spanish artist Marcial Rodriguez had given him a painting of unicorns fighting bulls when he was seventeen. Once he had the idea, he did research on unicorns at the Pittsfield Library.
