Revelation is the most representative works of apocalyptic literature, and the unique art of repetition can never be ignored. Or, we may say that the art of repetition is an important clue in understanding the book, while other apocalyptic literature (especially those literary works other than the Bible) is less identifiable than Revelation in this regard. Based on this, this paper will, by analyzing the dominant word repetition, repeated sentences and mind repetition, explore the repetition in order to deepen our understanding of the book and thus apocalyptic literature.
