‘En-Plein Air’ inscriptions are artistic interventions, by the artist Matteo Mauro, based on well-known Impressionist paintings, which algorithmically are added of new possibilities. The 19th century Impressionist painters re-imagined nature and captured their feelings in to artworks characterised by small, thin, visible brush strokes. The consequence was to emphasise the artists’ perception, rather than detailed reality. Movement and impermanence were elevated as crucial elements of human sensitivity and visual experience. In the ‘En-Plein Air’ inscriptions Matteo Mauro sees the possibility of opening up a dialogue between Impressionism and current technologies. The painting process begins with an analysis and understanding of the impressionist’s vision and painting methods. Thus, the historical source is not erased, but becomes a fundamental part of the new creation. The Impressionist’s strokes are sometimes celebrated and kept, others transformed in to a new abstract language, which formally raises or erodes the layers of 19th century paint. The constant growth of new and old strokes gives the painterly illusion of movement and spontaneity.
