Trees abound in Shakespeare's plays, and in Tree-Becoming, Shannon Kelley explores how he uses his characters' identification with cypress, balsam, bay laurel, myrrh, and pine trees as metaphors to express emotional distress. Opening new avenues for investigating knowledge of the plant world in early modern literature, Kelley traces the Ovidian conceit of arboreal transformation in A Midsummer Night's Dream, King Lear, Othello, and The Tempest. Through the recurring motif of tree-becoming, in which characters who can no longer endure painful feelings align with or are imagined as trees, Kelley proposes a radical reading of Shakespeare's depiction of trauma's lingering impact on the body and psyche. These arboreal moments resist resolution and resist healing, offering instead a vision of survival and endurance. Bringing Shakespeare in conversation with insights from critical plant and trauma studies, Tree-Becoming honors survivors of trauma as they are, not as we would have them be: they become trees – different, but not less than.
