Abstract: Questioning George Sand’s religious thinking from 1833 to 1842, during the period when she elaborates a singular religion invites us to cross two notions : personal evolution and literary creation. We aim at analyzing the way these ideas develop throughout narrative fictions which mirror one another (Lélia, Spridion, Mauprat) thanks to two major space patterns : the cloister and the garden. Both of them spring forth from an autobiographical imagery which is described in Histoire de ma vie.
