Jerzy Nowosielski was one of the premier 20th-century Polish artists—a painter, draftsman, stage designer, and iconographer. In his artistic output, he uniquely fused Byzantine artistic tradition with the modern language of contemporary painting. He created sacred icons and polychromies as well as nudes, landscapes, and abstract compositions, consistently maintaining a synthetic form and profound spiritual resonance. His works grace major museums and private collections, remaining among the most valued pieces of post-war Polish art on the market.
