Hybridity in the Literature of Medieval England offers a wide-ranging exploration of hybridity in medieval English literature. Anxiety about hybridity surfaces in characters of mixed ethnic identity in the romances. But anxiety is found also in the intersection of the natural and the supernatural and its site can be located inside the human body unstable physical frame, living and dead, as much as in the cultural and social forces at work upon the human body politic at large. Hybridity is unlike other constructs of difference in that, while it is grounded in difference, hybridity points toward sameness. The four types of hybridity studied in medieval English literature show that hybridity can resolve the problems caused by difference. Understanding medieval hybridity can help us to deal with our own contemporary struggles with the mixtures of our own lives and societies.
