Cross section of the human head

Wetselaar employed fine linework, stippling, and cross-hatching to model volume and texture. Bone surfaces are rendered with dense, angular strokes to suggest density, while soft tissues like the tongue and brain use smoother gradients. The precision of shadowing creates a three-dimensional effect, grounding the illustration in scientific observation rather than imagination.

The drawing was produced in the early 1970s and entered the Museum of Ethnography’s holdings shortly thereafter. It was likely used in teaching or public education, reflecting mid-20th century efforts to make human anatomy accessible through visual media. No record of prior ownership or exhibition exists beyond its institutional acquisition.

During the 1970s, anatomical illustrations remained vital in medical education, especially where photography was limited or impractical. Wetselaar’s work aligns with a tradition of hand-drawn dissection plates, bridging art and science. Its inclusion in an ethnographic museum suggests an interest in the human body as a cultural and biological artifact.

Though not widely published, the drawing exemplifies mid-century anatomical illustration techniques that prioritized clarity and detail. It remains a reference for understanding how pre-digital methods conveyed complex biological structures. Its presence in an ethnographic context invites reflection on how societies visualize and interpret the human form.
