This essay presents two concepts, ‘angular unconformity’ from geology, and ‘assymetrical repetition’ from astronomy, to use in approaching the Book of Esther. Esther, the final book added to the Hebrew Bible, is the only biblical book written by a woman. If it is a revelation, it is the final revelation in that tradition. The name of God does not occur in its text. Reading the Book of Esther points to a major scribal unconformity and pervasive assymetrical repetions on every level in interpreting the text’s theological silence.
