Focusing, like the next chapter, on romance perceptions and representations of space, this chapter is devoted to recapturing such perceptions in the context of medieval geographical discourse. Starting off with examinations of the role and specificities of medieval mapping, it highlights the textual nature of medieval learned discourse on the world and investigates ordinary people’s perception of their environment in the late Middle Ages. It argues that romance contributed to the fashioning of such perceptions, through its reliance on words rather than images, its tight interlacing of time and space, and its fundamental dependence upon enunciative dynamism (the movement by which stories are presented again and again to audiences). The space constructed by romance proves fundamentally dynamic while Breton lays feature several subtly distinct forms of spatial representation. Ranging from itineraries through linear networks to more map-like evocation of surfaces, they make varied use of the idea of contemporaneous spatial heterogeneity.
