Jo Niemeyer: Untitled - Archival n°468 (1992) An original painting by Jo Niemeyer, a central figure of contemporary Concrete and Constructive art. On a tall white vertical field, a sequence of pure colour elements descends in measured intervals: a solid blue band set high near the top, then a long, deliberate expanse of white, and lower down a quiet constellation of three smaller blocks — black at the right edge, red to the left, and a yellow rectangle stepped down beneath them. The primary triad and black are deployed without gradient, shadow or gesture; white is not a background but an active, dominant interval. The eye is made to measure distance, proportion and pause. This ordering is the core of Niemeyer's work. Since the 1960s he has built his compositions on mathematical systems, and above all on the Golden Section (phi), using proportion as a generative rule rather than a decorative effect. His subject is perception itself — of space, time, distance and proportion — and through it a synthesis of art and nature: a structured dialogue between mathematical order and the order observed in the natural world. The present canvas is a concentrated example, the intervals between the colour fields functioning as the true content of the picture. A unique work, acrylic on canvas laid on wood, hand-signed in pencil on the reverse and recorded in the artist's archive under no. 468. In pristine condition, the colours fresh and unfaded. The work is accompanied by a certificate of authenticity (COA) and a provenance report. Technique: Acrylic on canvas, laid on wood (unique work) Signature: Hand-signed in pencil on the reverse; archive no. 468 Dimensions: 80 × 36 × 4.5 cm Condition: Good condition with minimal signs of handling Provenance: Swiss private collection Accompanied by: Certificate of authenticity (COA) and provenance report Jo Niemeyer (born 1946) is a German-based Concrete artist, designer and mathematician. Working within the tradition of Concrete Art — the movement defined by Theo van Doesburg's Manifesto of Concrete Art of 1930 — he has made the Golden Section and mathematical proportion the generative basis of a body of work concerned with the perception of space and the relationship between art and nature. His paintings, prints and projects (among them Modulon and the land-art work 20 Steps Around the World) are held in public and private collections including the Museum of Modern Art, New York, the Pinakothek der Moderne in Munich, the Bauhaus-Archiv Berlin, the Stedelijk Museum Amsterdam and the Louisiana Museum of Modern Art, Humlebæk.
