After a short status quaestionis laying out the main perspectives from which the book of Revelation has been studied, we show how the study of the reading guidelines laid out in the Introduction have hitherto been overlooked. We propose the methodology to follow in order to discover them. According to the reading theory, every reader creates a ‘model’ through which the sense is grasped and the text interpreted. The elaboration of this model involves a process of ‘disassembling the mechanism without ruining it; disassembling it until the keys to its organisation are found’, according to Alonso Schökel. This process is what we will examine in the following chapters.
