Abstract: Although an article was devoted to flags as early as the tenth Bulletin de la Société Jules Verne, these have not elicited a political and poetic reading. This contribution draws up a typology of their presence in the Vernes’ work and identifies scenes where they play a poetic or dramatic role, before showing that the Vernes’ position is expressed in a displaced manner, through images integrated into a common patriotic didacticism, which illustrators and bookbinders maintain.
