The performance is based on the oldest saved text in slovene language written by capuchin Lovrenc Marušič, called Romuald Štandreški in 1721. Štandrež is a village near Gorica where Lovrenc was born. Later on he came to Škofja Loka where he performed his duty as a monk. Here he wrote Škofja Loka Passion Play. His typescript is kept in the Capuchin Convent but the fascimile can be seen only in the convent’s library in Škofja Loka town. Beside the fact that Škofja Loka Passion Play is the oldest slovene drama text, there exsists also the oldest drama directory book in Europe. Passion Play is also the biggest performance in the open air in Slovenia. Because of its origin, importance and richness of slovene language, Škofja Loka Passion Play is declared as a vivid masterpiece of state importance, so we stand as a candidate for the registration on the list of Unesco non-material cultural heritage.
