Examining the fairies of medieval romance as liminal beings, this book draws on anthropological and philosophical studies of liminality to combine folkloristic insights into the nature of fairies with close readings of selected romance texts. Tracing different meanings and manifestations of liminality in Sir Gawain and the Green Knight, Sir Orfeo, Sir Launfal, Thomas of Erceldoune and Robert Henryson's Orpheus and Eurydice, the volume offers a comprehensive theory of liminality rooted in structuralist anthropology and poststructuralist theory. Arguing that romance fairies both embody and represent the liminal, The Liminality of Fairies posits and answers fundamental theoretical questions about the limits of representation and the relationship between romance hermeneutics and criticism. The interdisciplinary nature of the argument will appeal not just to medievalists and literary critics but also to anthropologists, folklorists as well as scholars working within the fields of cultural history and contemporary literary theory.
