This chapter probes the links between the Baudelairean flâneur and the walking protagonist depicted in De Quincey's Confessions. Baudelaire famously writes that his poetry finds its roots in "the criss-cross of the innumerable interrelations' which the city is made of. The polysemy of the word croisement lends itself well to analyzing the flâneur's journey. It is a spatial term which refers both to physical movement and geography. It is a social term which provides a way to talk about encounters and connections, or lack thereof. Finally, it is a textual term which refers to the workings of intertextuality. Through the kaleidoscopic lens of this word, the flâneur appears as a figure who traverses space, time, and texts, and whose croisements were already at work in De Quincey's writing.
