A set of sermons believed to date back to the 13th or 14th century will be displayed at the National Library in Warsaw, on Saturday.
The Świętokrzyskie (‘Holy Cross’) sermons are regarded as the oldest pieces of prose writing in Polish. “The Świętokrzyskie sermons are one of the most valuable manuscripts, […] a cultural relic,” the director of the National Library, Tomasz Makowski, said. The manuscript is part of a exhibition that will display a cultural relic for a few hours once a month at the National Library. The exhibition marks the 1,050th anniversary of the baptism of Mieszko I, the first Christian ruler of Poland, marking the beginning of the Christianisation of the nation. The sermons are named after the monastery in south-central Poland where they were found, which is believed by some to house a small piece of wood from the cross on which Jesus Christ was crucified.
