Josilda da Conceição offers a duo presentation of Ruben Raven and Bart Stolle. Their bodies of work make use of similar motifs and tropes, and both have artistic vocabularies which are rooted in semiotics of manual and mechanical labor, natural and technological evolution and reproduction. On one hand, the collaborative aspects of Raven’s practice, and on the other, Stolle’s long-term research in digital multiplication, stipulate the intricacies of authorship in contemporaneous times. The vegetations commonly portrayed by Raven, alongside his observations of every-day decorative or recreational objects, telling of their handcraft or factory-made origins, are confronted by Stolle’s geometric compositions of unit-based logic, formally drawing back to the early modernist idiom.
