In this book, Barr applies narratological theory to the analysis of Revelation. As an attempt of narrative critical interpretation, it deserves to be read.
However, in my opinion, Barr fails to pay sufficient attention to the historical and biblical context and also provides a less than convincing outline of Revelation. Barr’s study is therefore more an interesting example of narrative critical analysis than a reliable guide to the interpetation of Revelation and its theology.
