'O'Byrne reconstructs pedestrianism as a spatial practice with specific codes and unique ways of seeing. Elegantly written, well-researched, and highly engaging, her study engages with a range of fascinating materials in multiple genres to open up new perspectives on the changing social dynamics of city walking in the eighteenth century.' Thomas Keymer, Chancellor Henry N. R. Jackman University Professor of English, University of Toronto 'O'Byrne's engaging interdisciplinary study reconstructs eighteenth-century poetics of walking in a range of genres, reading classics such as Gay's Trivia alongside spy books, pseudo-guides, and visual aids, from street characters, sites, and encounters to the 'diagonal mirrour' that reorders urban attractions as a three-dimensional optical illusion for the armchair traveller.'
