Who is Pope Clement from the novel, Wolf Hall?

Pope Clement is the head of the Catholic Church in all the world. Based in Rome, Pope Clement’s political situation is perilous, and at first, Henry VIII, Wolsey, and others conspire to supply the Pope with military resources and funding in exchange for an annulment in Henry’s marriage – an exchange which does not work. Repeated attempts to negotiate the annulment fail, and Henry marries Anne anyways. This causes Clement to prepare a papal bull of excommunication for Henry, and to condemn Henry’s marriage to Anne, though Clement dies by the end of the novel.
