The Woman clothed with the Sun makes a brief appearance in Revelation 12; however, her influence upon the imaginations of artists and interpreters is substantive. She is unnamed and yet multiple identities are ascribed to her including individual women (Eve, Mary), corporate institutions (Israel, the church), and ancient goddesses. In this article, rather than attempting to classify her with a definite identity, my goal is to destabilise this figure by aligning her with the monstrous. Using the lens of monster theory, I examine her otherworldly orientation, her hybrid and extraordinary body, and her correspondence with other monstrous characters. Her unknowability and refusal to fit interpretive categories are part of her monstrosity, as she moves across hybrid boundaries and liminal spheres.
