The theory of reading, as it is generally understood, concerns itself with procedures and problems associated with the interpretation of texts; reading is therefore studied primarily under the rubric of reception. One exception is the work of Clayton Koelb, which focuses steadily on reading as a productive, generative practice that can be investigated under the rubric of invention. Of course, understanding how a text comes into being greatly enhances the prospect of understanding how it can or ought to be performed; and thus the study of invention becomes a valuable aid in interpretation. Koelb's characteristic subject matter is therefore rhetorical construction in two interrelated senses: construction as the author's generation of structure, and construction as the reader's construal of meaning.

Although reading practices always manifest themselves in particular, historically determined forms, the theoretical issue of reading—the fundamental question of how human artifacts acquire and convey meaning—confronts every culture regardless of period, language, gender, ethnicity, or economic condition. For this reason, Koelb's conception of reading as an inventive practice turns out to be useful in studying texts from many different traditions, including some that fall outside his particular areas of expertise. This essay applies Koelb's ideas to a composite work of verbal and visual expression in a way not touched upon in his writing so far.
