The "La Mur murmura" writing can be found on an exhibited work by Guesselé-Garais and it reads in full:
La Mur murmura crûment qu'elle s'écoulera un jour entre tes murs et fera de ta structure qu'une grosse Gourde.
Translation: The Mur murmured bluntly and will one day overflow its banks and it will pour over your walls and turn your structure into a big pumpkin.
"La Mur" is a play on words here, as it can also be translated as "wall" and then creates a further reference to the Kunsthaus façade.
Olivier Guesselé-Garai has biographical roots in Cameroon and, together with Antje Majewski, has installed a multi-layered network between West Cameroon and Styria in the exhibition ARTS ⇆ CRAFTS.
