John of Patmos (also called John the Revelator, John the Divine or John the Theologian; Greek: Ἰωάννης ὁ Θεολόγος) is the name given to the author of the Book of Revelation, the apocalyptic text forming the final chapter of the New Testament. The text of Revelation states that the author is called John and that he lives on the Greek island of Patmos, where, by some, he is considered to be in exile as a result of anti-Christian persecution under the Roman emperor Domitian.
