Jerzy Nowosielski was a painter, graphic artist, scenographer, and illustrator, joint member of the Tadeusz Kantor circle and a member of the Kraków Group II. His practice could be described as an investigation of human spiritual states, mental processes, and desires through clean and very distinctive minimalist forms. Jerzy Nowosielski 's works have been part of many exhibitions and collections in Poland and abroad, such as the Venice Biennial, Italy; Sao Paulo Biennial, Brazil; Museum of Modern Art, New York, USA; Neue Nationalgalerie, Berlin, Germany; Musée d'Art Contemporain, Lyon, France; Kunsthaus, Nürnberg, Germany; Solomon R. Guggenheim Museum, New York, USA; Museum of Modern Art, Warsaw, Poland; Muzeum Sztuki, Łódź, Zachęta National Gallery of Art, Warsaw, Poland Poland; PGS - Państwowa Galeria Sztuki, Sopot, Poland, and many others.

Nowosielski’s most well-known works combine the tradition of Orthodox icon painting and the tendencies of the Western historical avantgarde. In the 1950s, Nowosielski dedicated his artistic practice to research and experiments, from figuration to geometric abstraction, like other representatives of the post-war Krakow avant-garde. Although the artist's style changed over time, it is usually easy to identify his works. The most characteristic elements of Nowosielski's work were elongated figures, mainly feminine, clear contours, clear colours, and flatness, reminiscent of early 20^th century avant-garde paintings. The work Abstract is part of the series of paintings in which he skillfully combined a thin black line outlining of squares, triangles, or, less often, circles, with pure, luminous colour, whose intensity often produces the effect of glowing forms.
