Ardiente Paciencia, or El Cartero De Neruda, is a 1985 novel by Antonio Skármeta. The novel was published in the English market under the title The Postman. It tells the story of Mario Jiménez, a fictional postman in revolution-era Chile, who befriends the real-life poet Pablo Neruda.
The novel is based on the motion picture of the same author released in 1983, and it was turned into another movie in 1995 as Il Postino, directed by Michael Radford. It was also turned in an opera, Il Postino, by Daniel Catán, with Plácido Domingo portraying Pablo Neruda (premiered at the Los Angeles Opera, 2010).
