Jan Matejko is often referred to as the "national painter" of Poland. He is  best known for paintings of notable historical Polish political and military events. The Lviv collection presented in Sopot shows the unknown to the wider public side of this great painter - in displayed sketches, often monochromatic, one can see Matejko's sense of humour, certain freedom and sensuality - the features that disappear in his grand finished paintings. Apparent is also his fascination with romantic love in his portrayal of King Stanisław August and Barbara. Jan Matejko , the deeply religious man, is also clearly visible in the works displayed at the exhibition. Lviv collection is enriched by the addition of Matejko's works from the National Museum in Warsaw and private collections.
