I read this anthology secondary to a friendly argument regarding the lives and letters of Abelard and Heloise and a discussion that sex and marriage had specific roles during the medieval period that would seem foreign to modern sensibilities.
It is essentially an academic text that discusses various perspectives directly through the writings of such luminaries as St. Augustine, Froissart, Chaucer, Constantine Africanus and others. The reader is not only introduced to various political, literary, economic, and theological viewpoints and uses of sex and marriage during the Middle Ages, but if you're observant you will see the viewpoints subtly changing during this vibrant thousand year period of pre-modern thought.
As a student of history with a particular interest in the medieval period, I found this text to be engaging, informative, and comprehensive -- covering the full European intellectual landscape. This is not a book about sex per se, but how and why certain behaviors were dictated by the theological-political rules of the time.
If you are new to reading about the Middle Ages, keep in mind that there are only two primary influences of thought: The theology of the developing Catholic Church, and the influences of the Roman Empire that preceded the Middle Ages. I think that this little book will stimulate your interest to read more about both of them.i
