This chapter starts from an interdisciplinary exchange between urban studies, mobility studies, and literary geography, and reads both urban narratives and spaces through a mobility-centred geocritical perspective. The analysis focuses on the mobile chronotope of the “tangential”, intended here as the ring road running around and through cities and as a plotline. Both the position of the tangential at the fringes of many contemporary cities and the mobile perspective of those “marginal figures” who traverse it seem to provide us with a de-centred critical approach, which allows us to resignify usually neglected urban spaces of transit through the interconnected practices of walking and writing. After an introduction, which brings mobility studies and literary geographies together, the chapter considers two examples by contemporary Italian authors (Gianni Biondillo and Michele Monina, Niccolò Bassetti and Sapo Matteucci) set along the tangential of Milan and Rome. If, according to Wylie, “the narrator is an outcome, not a presupposition, of the walk” (Wylie, A single day’s walking: narrating self and landscape on the South West Coast Path. Transactions of the Institute of British Geographers 30: 234–347, 2005), then the walker-writer enunciates and gives shape to urban space by walking across it (Pinder, Ghostly footsteps: voices, memories and walks in the city. Ecumene 8.1: 2–19, 2008; Errant paths: the poetics and politics of walking. Environment and Planning D: Society and Space 29: 672–692, 2011).
