A Life of Form and Geometry

Born in Amsterdam in 1924, Piet van Mook entered a world shaped by the legacy of his father, the painter Harry van Mook. His early years were marked by a quiet resistance; during the occupation, he refused to sign the loyalty oath required by German authorities, a choice that led him into hiding and away from his initial ambitions in biology. This period of concealment eventually gave way to a formal education at the Gerrit Rietveld Academie between 1946 and 1952. It was here that the foundations for a career spanning sculpture, painting, and graphic arts were laid.

After completing his studies, he settled in Gouda, where he balanced a life of teaching with a restless creative practice. As a drawing teacher at the Sint Antoniuscollege, he maintained a steady presence in the community while his studio work underwent profound shifts. His early output leaned toward expressionism, focusing on figures and landscapes rendered in oil and watercolor. However, as the decades progressed, the weight of the physical world seemed to give way to the logic of mathematics.

The Architecture of Impossibility

By the mid-1970s, a new preoccupation took hold. Van Mook began to move away from traditional representation toward abstract compositions and digital graphics. He became fascinated by the tension between structure and space, often exploring what are known as impossible forms. This fascination was not merely aesthetic but deeply rooted in mathematical principles. Through his involvement with the Ars et Mathesis foundation, he sought to bridge the gap between artistic intuition and geometric precision.

His sculptural work became a study in tensegrity—the principle of structural integrity maintained by a balance of tension and compression. Drawing inspiration from the mechanics of Buckminster Fuller and Snelson, he constructed complex spatial arrangements using tubes and cables. One notable example, the Vijfvoudpiramide, stands in Park Vijversburg, Dwaalster. This work, created in 2001, utilizes three-meter-long tubes and tetrahedrons to create a transparent, geometric presence that appears to float despite its monumental scale.

A Legacy of Precision

The breadth of his technical skill allowed him to navigate various media with equal rigor. Whether working with the digital precision of computer-aided graphics or the tactile nature of oil on canvas, the underlying interest remained the same: the exploration of balance and contrast. His exhibitions at venues such as MuseumgoudA and the Teylers Museum in Haarlem reflected a career that refused to remain static.

In his later years, living in Bergambacht, he continued to refine his investigations into shape and structure. His contributions to the art scene included:

• The creation of Trisquare, a complex puzzle-like sculpture that challenges the viewer's perception of volume and void.
• The development of digital graphic works that translated musical notations into visual patterns.
• The publication of writings on structure and construction, documenting his variations on mathematical forms.

Piet van Mook passed away in 2016, leaving behind a body of work that transitioned from the emotional weight of expressionism to the cerebral clarity of abstract geometry. His life was defined by a persistent effort to find harmony within complex, often contradictory, structures.
