Plot
Set in a postapocalyptic world, A Canticle for Leibowitz follows the monks of the Albertian Order of Leibowitz in their quest to preserve knowledge after a devastating nuclear war. The story spans thousands of years, beginning 600 years after the war in a monastery in the southwestern United States. A young novice named Brother Francis discovers ancient documents belonging to the order's founder, Isaac Leibowitz, leading to Leibowitz's canonization as a saint.
The second part takes place 600 years later, as a new Renaissance is beginning. A secular scholar named Thon Taddeo visits the monastery to study its preserved knowledge. Meanwhile, political tensions are rising between city-states, with the mayor of Texarkana seeking to expand his power and control. The abbot refuses to allow the monastery's documents to be taken away, offering instead for research to continue on-site.
Another 600 years pass, and humanity has once again developed advanced technology including nuclear weapons and space travel. As tensions rise between two global superpowers, the monastery prepares to evacuate some of its members to a space colony to preserve human knowledge in case of another apocalyptic war. A nuclear incident occurs, followed by a brief ceasefire and then full-scale war.
As nuclear explosions begin, the abbot is trapped in the monastery's ruins. Before dying, he encounters a two-headed mutant woman who seems to perform a miracle. The novel ends as the monastery's chosen crew launches into space, leaving behind a world once again descending into nuclear devastation. A final scene depicts the effects of the war's fallout on marine life.

Setting
The novel A Canticle for Leibowitz is set in a postapocalyptic future, spanning nearly 1800 years after a devastating nuclear war known as the “Flame Deluge” has destroyed modern civilization. The story takes place primarily in the southwestern United States, centered around a Catholic monastery in the desert of what was once New Mexico.
The narrative is divided into three parts, each set 600 years apart. The first section occurs in the 26th century, during a new Dark Age where scientific knowledge has been largely lost. The second part is set in the 32nd century and depicts the beginnings of a new Renaissance. The final section takes place in the 38th century, when humanity has once again developed advanced technology including nuclear weapons and space travel.
The monastery serves as an oasis of learning in a world that has regressed to medieval levels of technology and literacy. As humanity slowly rebuilds over the centuries, the abbey remains a constant, guarding the relics of the past in hopes of eventually restoring lost knowledge and preventing another catastrophe.
Characters
Brother Francis Gerard: A young novice monk who discovers ancient artifacts from before the nuclear apocalypse. His discovery leads to the canonization of Saint Leibowitz. Francis is naive but devoted to his faith. He spends years creating an illuminated copy of a blueprint he found, only to have it stolen on his journey to New Rome.
Abbot Arkos: The stern leader of the abbey in the novel’s first section. He is skeptical of Brother Francis's claims about finding the Leibowitz artifacts and worries it may delay the canonization process. Arkos represents the more dogmatic aspects of the Church.
The Wanderer/Benjamin: A mysterious figure who appears in all three sections of the novel, possibly immortal. He encounters Brother Francis in the desert and later settles as a hermit near the abbey. The Wanderer seems to have knowledge spanning centuries.
Thon Taddeo Pfardentrott: A brilliant secular scholar in the novel’s second section who visits the abbey to study the Memorabilia. He is compared to Galileo and makes several scientific “discoveries” by studying the preserved knowledge. Taddeo represents the rediscovery of lost knowledge.
Dom Paulo: The abbot during the second section. He allows Thon Taddeo to study at the abbey but refuses to let the Memorabilia be removed. Paulo struggles with balancing the preservation of knowledge and the potential for its misuse.
Abbot Zerchi: The leader of the abbey in the final section as nuclear war once again threatens humanity. He oversees the implementation of a plan to preserve the Church and knowledge on other planets. Zerchi debates issues of euthanasia as refugees flood the abbey.
Brother Joshua: A young monk chosen to lead the mission to preserve the Church on colony planets. He represents hope for humanity's future as he departs Earth before its destruction.
Mrs. Grales/Rachel: A two-headed mutant woman encountered by Abbot Zerchi at the novel’s end. The Rachel head appears to be a new, sinless being, possibly representing hope for humanity's redemption.

About the Author
Walter M. Miller Jr. (1923-1996) was an American science fiction writer. His most famous work A Canticle for Leibowitz was published in 1959 and won the Hugo Award for Best Novel in 1961. This postapocalyptic novel, which explores themes of history, religion, and human nature, is considered a masterpiece of the genre.
Born in New Smyrna Beach, Florida, Miller served as a radioman and tail gunner in World War II, flying more than 50 bombing missions in Italy. He was deeply affected by this experience, particularly his involvement in bombing the Benedictine Abbey at Monte Cassino. After the war, Miller converted to Catholicism and began his writing career. Between 1951 and 1957, he published numerous science fiction short stories, winning a Hugo Award in 1955 for “The Darfsteller.”
Despite the success of A Canticle for Leibowitz, Miller never published another novel during his lifetime. He became increasingly reclusive in his later years, struggling with depression and avoiding contact with nearly everyone, including his family. His experiences during the war likely contributed to what would now be diagnosed as post-traumatic stress disorder.
Miller's life came to a tragic end when he took his own life in January 1996, shortly after his wife's death. At the time, he had nearly completed a 600-page manuscript for a sequel to Canticle. This work, titled Saint Leibowitz and the Wild Horse Woman, was finished by science fiction writer Terry Bisson at Miller's request and published posthumously in 1997.
