A breakthrough in the study of the history of human sexuality came with the publication of Michel Foucault’s still highly important, though now classic book. Looking at Poland, one can observe that the Polish historiography of the nineteenth and twentieth century, did, of course, feature reflections on certain phenomena associated with the sphere of satisfying sexual desire; phenomena such as marriage, celibacy, or prostitution, but there was no comprehensive approach to medieval sexuality. The first attempt to use Foucault’s research ideas in a study on the topic in question was Adam Krawiec’s book Seksualność w średniowiecznej Polsce (Sexuality in Medieval Poland). Krawiec undertook the important work of collecting references to sexual behaviour scattered across various types of Polish sources. A certain pattern emerges from his book: While the number of available sources is limited in the first centuries of Polish statehood, the amount grows in accordance with the growth of literacy, the spread of preaching and, finally, the emergence of the ecclesiastical judicial system. At first glance, the pattern appears banal. But it only seems to be so.
