Prior to the 19th century only Daniel Schultz and Italian-born Marcello Bacciarelli had the privilege of being recognized abroad. The Young Poland movement witnessed the birth of modern Polish art, and engaged in a great deal of formal experimentation led by Jacek Malczewski, Stanisław Wyspiański, Józef Mehoffer, and a group of Polish Impressionists. Stanisław Witkiewicz was an ardent supporter of Realism, its main representative being Józef Chełmoński, while Artur Grottger specialized in Romanticism. Within historically-orientated circles, Henryk Siemiradzki dominated with his monumental Academic Art and ancient Roman theme.
