When Juno transforms Callisto into a bear, the text observes: “Yet her mind was unaltered. Her lament / Was the roar of a bear — but her grief was human. / And though they were a bear’s forepaws / That she raked at heaven’s face with, / Her despair over Jove’s ingratitude… was a girl’s.” How does this detail most directly shape the reader’s understanding of Callisto’s punishment?
