Catalogue of the project Aeronautics Interior [Flight], an installation by the artist Francesc Torres that brought two life-size aeroplanes to the Oval Hall, replicas of two types of plane that took part in the Spanish Civil War. In this project, Francesc Torres takes coordinates that he has previously explored even further, such as the ambiguity between art and non-art (camouflage painting, non-artistic objects with an artistic aura, etc.) or the elimination of the dividing line between the formats exhibition, work and installation. In the installation the artist explores aspects such as the impact, within the conflict, made by the war in the sky, or the idea of sacrifice, which he relates to works of art in the museums historic collection. To explain the link between sacrifice in wartime and sacrifice because of religious faith, Torres plays with the iconography of the crucifixion and, especially, the Gothic painting The Crucifixion of Saint Peter, by the master Pere Serra (14th century).
