The term "Carthusian" refers to a member of the Carthusian Order, a Roman Catholic monastic order founded in 1084 by Saint Bruno in the Chartreuse Mountains of France. Carthusians are known for their strict adherence to a life of solitude, prayer, and contemplation, living in individual cells and coming together only for communal worship. Carthusian spirituality emphasizes silence, simplicity, and a deep connection with God. The order is characterized by its unique lifestyle, which includes a commitment to asceticism and a focus on the inner life. Carthusians are also known for their contributions to Christian mysticism and the production of Carthusian wine.
