Abstract: The staging of texts by Verticales authors has been based on stage writing (Tackels, 2005) and plays around with orality and hybridity. Is co-authorship practiced, including during a publication? Which scenography (Maingueneau, 2004) can be identified when the status of the speaker remains ambiguous? Are theatrical process and editorial enunciation (Ouvry-Vial, 2007) compatible, complementary, or conflicting?
