Jean-Marie Appriou’s sculptural research aims to build oneiric landscapes populated with human, vegetable and animal bodies, captured in spatial configurations with a strong allegorical and narrative nature. The characters move within theater plays suspended between deep memories of an indefinite past and the uncertainties of the future, in a widespread temporality, characterized by a mythical halo. The coexistence of recognizable natural forms, albeit hybrid and in constant evolution, often indecipherable narrative dimensions and allegorical plans gives the artist’s works a layering of multiple possible readings. The use of different materials, from glass to metal, participates in the plastic definition of these worlds, intended as doors, bridges and thresholds for the search for further dimensions, keys to other perceptions of the visible. In the works on exhibition, Écume Métallique and Vapeur Métallique (both 2018), the idea of the access door to an “other” space is clearly featured. Similar to grotesques, the elements of the sculptures recall an underwater or underground world in which the different states of matter—solid, liquid and gaseous—as well as the different natural realms—mineral, vegetable and animal—articulate in space with no interruption. The two sculptures stand in the space like two distinct rock conformations, crystallized in the movements of the creatures that inhabit them, but at the same time crossed by an organic, hybrid and metamorphic force.
