Hanne Darboven’s 1966/67 Konstruktionen New York [Constructions New York] are at the point of transition from her early perforations to the more rigorously conceptual sequences of drawings. Individual sheets from the Konstruktionen drawings show punctures on the construction lines — these perforations are variations on the dot grid of Almir Mavignier’s pictures — Mavignier was Darboven’s teacher in Hamburg — and the reliefs of the ZERO group. The monochrome material pictures in which she worked among other things with needles and screws on hardboard sheets are predecessors from Darboven’s time as a student in Hamburg. Here the fine graph paper squares form a reference structure for the drawn outlines. Various redeployments in the sequence of certain elements are played out within the line formations, which are usually diagonal. These are based on previously noted numerical process sequences and symmetrical/ mirror-symmetrical arrangement systems.
