Set in 19th-century Sicily, The Miracles of Antichrist explores themes of faith, revolution, and social change. The novel follows the story of an ancient statue of Christ that, after being mistaken for the Antichrist, starts to perform miracles with unintended consequences. As the island's people grapple with the tension between spiritual belief and political upheaval, Lagerlöf weaves a narrative rich in symbolism, exploring the conflicts between religion, socialism, and personal faith.
