Art's function has allowed artists to express themselves for centuries. Art was once created solely for religious reasons, especially with the rise of the Catholic Church. The Industrial Revolution and the church's declining influence in the 19th century opened people's eyes to emotion and imagination, which Romanticists later portrayed artistically. This led to nature mysticism and landscape paintings. Similarly, St. Ignatius' Ignatian Spirituality corresponds to the divine yearning in nature. Spirituality and art can go hand in hand, say Jesuit priest-artists. Mystical landscapes reveal humanity's spiritual connection to nature. Artists explore emotion and spirituality through monochromatic art because it can provoke deeply personal experiences.
