I offer a small contribution to the current debate regarding the genre of the Book of Revelation. My research is motivated by the tantalising obser- vation that John employs prolific sources uniquely and at times generically. These offer invaluable clues - arguably the best available - to his own self- identity. The results of several prior source-critical studies demonstrate the scope and nature of John's sources. My specific source-critical contribution is a detailed analysis of the manner in which John uses his major sources, especially with forceful generic intent. However, this analysis is conducted in stringent compliance with the dictates of cogent generic criticism.
