"4 Parts" and "Z.K." are harbingers of Aroch's later works. Both are ostensibly abstract, but the concreteness of 4 Parts is no less than that found in the Tzakpar series and the broken lines in Z.K. reproduce, as testified by the artist, an associative link with the measurements drawn by the tailors of Aroch's childhood.
From here to Aroch's expanding interest in the craftsmanship involved in making the painting, the way is short. (Yona Fischer, Catalogue: "Itineraries and Forms")
