About this work
Overview
Created in 1965 by H.G. Wetselaar, this drawing titled “Digestive system” is part of the collection at the Museum of Ethnography. The work consists of a dense network of interlaced lines that coil and intersect, forming a compact, knotted mass with a small, curved protrusion at one edge.
Subject & Meaning
Although the title suggests an anatomical reference, the composition does not depict a literal organ. The tangled filaments evoke the idea of convoluted passages, inviting viewers to consider the complexity of internal bodily processes or, more broadly, the intricate pathways that connect and sustain systems.
Technique & Style
Wetselaar employs a monochrome drawing technique, using continuous, rope‑like strokes that overlap and twist. The abstracted forms rely on line density and negative space to create a sense of depth, while the occasional hook‑shaped element adds a subtle focal point within the overall entanglement.
History & Provenance
The piece entered the Museum of Ethnography’s holdings shortly after its creation, becoming part of the institution’s mid‑20th‑century graphic art collection. Its acquisition reflects the museum’s interest in works that explore cultural and biological themes through abstract visual language.
