The origins of Polish literature written in Polish go back beyond the 14th century. In the 16th century the poetic works of Jan Kochanowski established him as a leading representative of European Renaissance literature. Baroque and Neo-Classicist belle letters made a significant contribution to the cementing of Poland's peoples of many cultural backgrounds. The early 19th century novel "Manuscrit trouvé à Saragosse" by Count Jan Potocki, which survived in its Polish translation after the loss of the original in French, became a world classic. Wojciech Has's film based on it, a favourite of Luis Buñuel, later became a cult film on university campuses. Poland's great Romantic literature flourished in the 19th century when the country had lost its independence. The poets Adam Mickiewicz, Juliusz Słowacki and Zygmunt Krasiński, the "Three Bards", became the spiritual leaders of a nation deprived of its sovereignty, and prophesied its revival. The novelist Henryk Sienkiewicz, who won the Nobel Prize in 1905, eulogised the historical tradition. It is difficult to grasp fully the detailed tradition of Polish Romanticism and its consequences for Polish literature without a thorough knowledge of Polish history.
