Roger Bolingbroke is a conjurer hired by Eleanor Cobham, Duchess of Gloucester, to summon spirits and divine the future. He appears only in Act 1, Scene 4, where he participates in the dark magic circle that brings forth a spirit to answer questions about the fates of King Henry VI, the Duke of Suffolk, and the Duke of Somerset. Bolingbroke’s conjuration is conducted with ceremonial precision—he speaks Latin incantations, controls the circle’s mystical space, and ensures the spirit remains bound within the sacred boundary. His role is to be the technical master of the ritual, the one who knows the proper words and gestures to breach the boundary between the mortal and spirit worlds.
Though Bolingbroke speaks little, his function in the play is crucial: he enables Eleanor’s ambition by translating her desire to know the future into magical practice. He reads the prepared questions aloud, directs the spirit to speak, and records its answers in writing—a detail that proves fatal to Eleanor’s scheme, since the written prophecies become evidence of treason when York and Buckingham burst in to arrest the conspirators. His calm professionalism, his command of Latin and ritual language, and his authority in the magical circle all mark him as educated and skilled in his dark art. Yet this very skill—this ability to write down what the spirit says—becomes the trap that snares Eleanor. Bolingbroke is one of those minor characters whose competence and service to a greater power makes him complicit in a larger downfall. He asks no questions about why Eleanor wants to know these things, offers no moral resistance to her ambition. He is simply a tradesman of the impossible, selling prophecy and witchcraft to those desperate enough to buy.
Bolingbroke’s arrest and execution at the end of Act 2, Scene 3, happens offstage. We learn only that the witch Margaret Jourdain is to be burned to ashes, and the conjurer and his associates are to be strangled on the gallows. His brief appearance and swift punishment reflect the play’s treatment of witchcraft as both real and damnable—a genuine breach of natural law that draws God’s swift judgment. In Bolingbroke, Shakespeare captures the figure of the educated criminal, the man whose learning and skill have been bent toward forbidden ends, and whose fate is therefore sealed not by ignorance but by knowledge itself.
By water shall he die, and take his end.
He will die by drowning, and that will be his end.
Roger Bolingbroke · Act 1, Scene 4
Suffolk's fate is sealed by a three-word prophecy that appears to condemn him to drowning. Yet when Walter Whitmore kills him at sea, it is not by water in the literal sense—the name itself becomes a pun on the prophecy. The play demonstrates how fate and language are slippery, and how the future resists being known, even when spirits speak.
The duke yet lives that Henry shall depose; But him outlive, and die a violent death.
The duke still lives, but Henry will remove him from power; But he will outlive Henry, and die a violent death.
Roger Bolingbroke · Act 1, Scene 4
The conjured spirit speaks a prophecy that is ambiguous by design—it could mean York will outlive Henry, or that the duke will be outlived by someone else. The play's central theme is that language and prophecy are unreliable; this line shows how words can have multiple meanings and how characters misinterpret what they hear. The spirit's cryptic response mirrors the play's concern with what texts actually say versus what people believe they say.
