|Walter M. Miller Jr.|
Walter M. Miller Jr. was an American author of science fiction, known for a single book that has become a classic: A Canticle for Leibowitz, possibly one of the best science fiction novels of all time, at least among those in the apocalyptic sub-genre, which describes what might happen after a total nuclear war.
The novel is divided into three parts: In the first, Fiat Homo, the world is just beginning to recover from the disaster. As in the centuries following the fall of the Western Roman Empire, the Catholic Church takes the responsibility for saving what little remains of classical culture (ours) through the monks of an order founded by one man, Leibowitz, who before the nuclear conflagration was an electrical engineer. In the second part, Fiat Lux, several centuries have gone by, a new civilization has emerged and the world is entering a new Renaissance. In the third, Fiat Voluntas Tua, this civilization has reached its peak, materialism comes back, and history threatens to repeat itself. But this time Miller leaves a possible escape open: the colonization of the galaxy.
