"Spiridion" by George Sand is a novel published in 1838-1839. Set in an eighteenth-century Italian monastery, it follows Angel, a young novice tormented by mysterious visions of a long-dead founder. Under the guidance of the elderly monk Alexis, Angel discovers a hidden history of spiritual heresy within the monastery walls. As Alexis reveals the secret transformations of the enigmatic Spiridion—who journeyed from Judaism through Protestantism and Catholicism to his own dangerous truth—Angel must confront questions of faith, doubt, and forbidden knowledge concealed in a tomb.
