A raw, conceptual work by Dutch artist Anton Heyboer, featuring handwritten text and geometric diagrams on aged paper.

Anton Heyboer, a Dutch artist known for his reclusive lifestyle and idiosyncratic visual language, produced a vast body of work that often blurred the lines between personal diary, mathematical system, and visual art. Papier nummer 43 is a representative example of his practice, which frequently utilised found paper, handwritten text, and schematic diagrams to map his internal philosophy. The work features a central, radiating geometric structure, reminiscent of a star or a compass, which serves as an anchor for the surrounding annotations. Heyboer’s process was deeply personal, often involving the creation of complex, self-referential systems that attempted to quantify human experience, trauma, and psychological states. The inclusion of Dutch text, written in a hurried, cursive hand, provides a narrative layer that invites the viewer to engage with the artist's specific, often cryptic, logic. The use of collage, with a prominent vertical strip of paper obscuring part of the composition, suggests a process of layering and revision, common in his output. The paper itself, aged and textured, acts as a physical record of his environment and his method of working in isolation. This piece avoids traditional aesthetic conventions, favouring a raw, unmediated expression that aligns with the principles of Art Brut. The lines are thin and deliberate, forming a web of connections that feel both scientific and deeply subjective. By presenting his thoughts as a visual map, Heyboer invites an examination of the relationship between language and image. The work functions as a document of his mental architecture, offering a glimpse into a private world where numbers, words, and symbols are woven into a singular, cohesive system of meaning.
