"Crossing Borders is a bold and groundbreaking work. Situated at the nexus of queer theory and postcolonial medievalism, it interrogates and seeks to conjoin two significant areas of inquiry: the literary representation of lesbianism and the influence of Arabic traditions on medieval French narrative. Working across a range of genres in both languages, Sahar Amer unearths hitherto unrecognized allusions to lesbianism in Old French texts, arguing that these represent traces of Arabic influence on the key genres of romance and epic."
