Marie-Isabelle Callier, born in 1970, is a Belgian-Luxembourgish artist who trained in illustration at Saint-Luc in Brussels. After a career in advertising, she devoted herself to painting and children’s books. Since 2018, her works in waxed and cut paper, arranged in diptychs, triptychs, screens, altarpieces, and dioramas, have been exhibited at major art biennials, from Luxembourg (De Mains De maîtres) to Venice. For Nature singulière, she presents a series of backlit dioramas, a way of recreating a scene in three dimensions. Each piece explores a rare or endangered plant world: the Andean páramos, water reserves, unique high-altitude biotopes, nocturnal gardens, plants that continue to breathe at night, Luxembourg’s rose gardens, a heritage, endangered flowers, and even the mysterious garden of a fairy tale. Through these poetically fragile landscapes, she emphasises the urgency of their preservation. Her technique combines indigo watercolour, encaustic wax on Japanese paper, meticulous cutting and layering, creating plays of transparency and depth, allowing viewers to lose themselves in the landscape and immerse themselves in the heart of an endangered beauty.
