Henryk Hektor Siemiradzki (1843 ? 1902) was a Polish 19th-century painter active in the period of foreign Partitions of Poland, and best remembered for his monumental Academic art. He was particularly known for his depictions of scenes from the ancient Graeco-Roman world and the New Testament, owned by national galleries of Poland, Russia and Ukraine. Many of his paintings depict scenes from antiquity, often the sunlit pastoral scenes or compositions presenting the lives of early Christians. He also painted biblical and historical scenes, landscapes, and portraits. His best-known works include monumental curtains for the Lwów Theatre of Opera and for the Juliusz Słowacki Theatre in Kraków. Henryk Siemiradzki's large-scale canvasses, influenced by the French Académie des Beaux-Arts, are on display at the national museums of Poland, Russia and Ukraine; notably, at the Sukiennice Museum, the National Museum, Poznań, Lviv National Art Gallery, Tretyakov Gallery and others.
