Since Ovid’s first-century Metamorphoses, transformative experiences and transformed selves have been fundamental sites of interest in European literature. At times bewildering, marvelous, and horrid, these physical transformations can invite readers to reconsider their bodies and, because of Ovid’s moral ambiguity, to reconsider their morality and thus to reconsider themselves. The powerful idea of transformation has shaped medieval and early modern thinking, a specter heralding what is yet to come, whether feared or longed for. Transformations can be violent, often involving aggressive bodily catalysts, or even death. But other transformations are rapturous, holy epiphanies. Transformations can be sly and illusory, indiscernible yet suspected.
