The Book of the Revelation contains outlined studies of the last book of the Bible. In his introduction, Strauss says, "Genesis is the book of commencement; Revelation is the book of consummation." The author identifies three distinct systems of interpretation of Revelation--The Preterist School, The Presentist School, and The Prophetic School. Subscribing to the latter, Strauss holds that the largest part of the Book of Revelation is prophetic, and thus it applies to a period still future.
