Areshima is the name of a Neolithic site in the Ténéré desert in Niger, where stone tools (grinding stones, arrowheads, axes, etc.) were found. The flattened almond shapes developed by Bernard Dejonghe for this series may recall these objects from the early days of humanity. But the artist, by enlarging them excessively, distances them from representation in favour of a research focused on matter. The copper red, in particular, allows him to create infinite networks of veins which are so many signs of what is at work in the mineral world: "I try to bring out, with these materials, the energy that I feel in the stones." The discoverer in 2000 of the Tafassasset meteorite in Niger, Bernard Dejonghe roams deserts in search of traces of astral energies (Libyan glass, impactites, etc.).
