This synthetic study has two primary tasks. The first is to elucidate the structure of the book of Zechariah. But in order to do this, a satisfactory method of analysis must be found. Thus the author begins by drawing up suitable literary criteria that will help to frame a reliable way of proceeding. The method is then tested on the book of Zechariah, and the results are compared with those of other biblical scholarship. Although this is a study in 'rhetorical criticism', it approaches the text from the standpoint of the authors' and redactors' intentions. The result is a convincing and wide-ranging analysis of the various and complex structural patterns of Zechariah.
