In Aristotle’s Poetics, the well-constructed turning point, peripeteia, makes a story by unfolding its tragic – or, more broadly, literary – potential. But neither narrative nor historical turning points occur in empty spaces. Given the power of the peripety for plot-making, this volume inquires about its agency in the shaping of specific regions. Narration matters, for the constitution of events and regions alike; space matters, as a key element for the construction of plots and their dynamics. The Baltic Sea region, with its rich literary and cultural traditions and multiple overlapping layers of historical ruptures, is a particularly fruitful area for exploring transformation processes from a narratological point of view.
