The churches and manuscripts of medieval Europe incessantly juxtapose imagery depicting sacred themes with likenesses of the crudest and basest nature. This book examines such contrasts in six major works of pre-1350 Spanish literature, arguing that medieval writers and artists subscribed to the classical belief that one must introduce the contrary of a concept in order to elucidate it fully. To explain this play of opposites, the author draws on the contrast between Bakhtin's concept of the carnivalesque, which embodies and portrays the realm of desire, and the domain of the law, which imposes the social and behavioral restraints upon ...

How, then, can we account for this polar structure in medieval art and letters? The author argues that people of the time tended to understand artistic works in a manner analogous to the layout of a medieval manuscript page. The central part carries the most important message, yet in the periphery (the margin) one finds a commentary that is often essential to a complete understanding of the whole. Moreover, text and commentary oscillate: what is central can become peripheral, and what is "outside" can move to the core of a document's explicitly thematized concerns.
