Provenance Galleria Cadario, Milan Private collection, Italy (acquired from the latter) Then by descent to the current owner 11 April 1957: the first "one-night exhibition" took place, becoming the founding act of the ZERO group. A veritable artistic and spiritual revival committed to redefining art in the ashes left by the war, this group envisaged intellectual reconstruction driven by an ideal: to transcend the boundaries of the visible in order to reveal the infinite. Otto Piene and Heinz Mack, the theoreticians and founders of this group, played on the perception of space, inviting the viewer to immerse themselves in their creations. Their new aesthetic paradigm is based on light and its dynamics. "Light is my brush and the sky my canvas", said Otto Piene. A year later, in 1958, the eponymous magazine was launched, confirming the strong commitment of these two artists, joined by Gunther Uecker in 1961, to the primacy of the mind over the hand. The Alfred Schmela gallery in Düsseldorf, the real home of this group, was the venue for a number of exhibitions in which Yves Klein took part, notably in April 1958. A spiritual father, he was, along with Fontana, ZERO's major point of reference. These artists shared with the NUL group, the Gruppo Nucleare and Gutaï the desire to make the intangible tangible, because "in every shadow lies the promise of light" (Heinz Mack). (Heinz Mack). The two works we are presenting, dating from the early 1960s, were both acquired from Galleria Cadario (Milan). Never shown on the market since, they have remained in the collector's family to this day. 11 April 1957, a first "pop-up exhibition" took place; it would lead to the founding of the ZERO Group. A radical artistic and spiritual movement committed to reinventing art from the ashes and rubble left by the war. The only authentic intellectual reconstruction the group could envisage had to reflect a concept: escaping the boundaries of the visible in order to reveal the infinite. Otto Piene and Heinz Mack, the theoreticians and founders of the group, toy with the perception of space, thus inviting the viewer to immerse themselves into their creations. Their new aesthetic paradigm is driven by light and its dynamics. "Light is my brush and the sky my canvas", said Otto Piene. A year later, in 1958, the eponymous magazine was launched, confirming the two artists' strong commitment-joined in 1961 by Gunther Uecker-to the primacy of the mind over the hand. The Alfred Schmela Gallery in Düsseldorf-actually the group's haunt-was the venue for various exhibitions in which notably Yves Klein took part, in April 1958. He was, along with Fontana, a spiritual father, ZERO's major point of reference.
