The title "Area 125" by Ryszard Winiarski was made in tempera on a fibreboard relief in 1973. The artist's realisations depart from the traditional perception of a painting as an aesthetic object. They are a graphic record of the creative process, the result of choosing a specific method, a rule of conduct. The arrangement of the individual colour fields is not determined by deliberate shaping, but by chance or logic - the toss of a dice, a coin or a programmed computer. The visual effect is generated by a mathematical system. The primary role of the process of creation of the work, situating it within conceptualism, made Winiarski an artist ahead of his time.
