An evidence of the representation of the world and thus of space, an effective pedagogical medium, an attractive ornamentation by the way of quotations or epigraph, such are the main known and recognised uses of literature in Geography. Beyond these various approaches, which relevance is no longer to be demonstrated, literature could be considered for its efficiency, for its role in the formation of space representations and more particularly in urban representations. This issue corresponds to the orientation given to a current research work which some ins and outs will be given in this article. The presuppositions underlying the reflection of literature as a source for the creation of matrix that structure urban representations will be provided in a short theoretical approach. Then, a case study will be proposed in order to give an understanding of the process through which these matrixes are reintroduced or instrumentalised by different urban actors and integrated in the strategies implied in the urban making and evolution. The matter in hand is the political instrumentalisation of the tentacular urban matrix born in Belgian poet Emile Verhaeren's work in the speech on decentralisation and large complexes of French President de Gaulle 's construction minister, Pierre Sudreau.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
