written during the Occupation of Poland appeared in print only after the conclusion of World War II, including books by Nałkowska, Rudnicki, Borowski and others. The situation began to worsen dramatically around 1949–1950 with the introduction of the Stalinist doctrine by minister Sokorski. Poland had three Nobel Prize winning authors in the later 20th century: Isaac Bashevis Singer (1978), Czesław Miłosz (1980) and Wisława Szymborska (1996). In the early 21st century, yet another writer was awarded the Prize: Olga Tokarczuk. Middle Ages Almost nothing remains of Polish literature prior to the country's Christianization in 966. Poland's pagan inhabitants certainly possessed an oral literature extending to Slavic songs, legends and beliefs, but early Christian writers did not deem it worthy of mention in the obligatory Latin, and so it has perished. Within the Polish literary tradition, it is customary to include works that have dealt with Poland, even if not written by ethnic Poles. This is the case with Gallus Anonymus, the first historian to have described Poland in his work entitled Cronicae et gesta ducum sive principum Polonorum (Deeds of the Princes of the Poles), composed in sophisticated Latin. Gallus was a foreign monk who accompanied King Bolesław III Wrymouth in his return from Hungary to Poland. The important tradition of Polish historiography was continued by Wincenty Kadłubek, a thirteenth-century Bishop of Kraków, as well as Jan Długosz, a Polish priest and secretary to Bishop Zbigniew Oleśnicki. The first recorded sentence in the Polish language reads: "Day ut ia pobrusa, a ti poziwai" ("Let me grind, and you take a rest") – a paraphrase of the Latin "Sine, ut ego etiam molam." The work in which this phrase appeared reflects the culture of early Poland. The sentence was written within the Latin language chronicle Liber fundationis from between 1269 and 1273, a history of the Cistercian monastery in Henryków, Silesia. It was recorded by an abbot known simply as Piotr (Peter), referring to an event almost a hundred years earlier. The sentence was supposedly uttered by a Bohemian settler, Bogwal ("Bogwalus Boemus"), a subject of Bolesław the Tall, expressing compassion for his own wife who "very often stood grinding by the quern-stone." Most notable early medieval Polish works in Latin and the Old Polish language include the oldest extant manuscript of fine prose in the Polish language entitled the Holy Cross Sermons, as well as the earliest Polish-language Bible of
