 In the history of culture of Lithuania, unfortunately, is still dominated by traditional monoparadigmatic method of research with catholic hierarchization, continuing the line of the Polish historiography of the 19th - 20th centuries.In 2012, Bučys published "History and Anthology of Ancient Lithuanian Literature" with 13 texts in old Slavonic and Church Slavonic languages, most of them were sacred and were never presented in the context of Lithuanian culture.Among them – medieval “Vita of Vaishvilkas”, the son of king Mindaugas, who founded in the middle of the 13th century one of the oldest monasteries of the Greek rite on the bank of the Nemunas river, and other sacred texts, devoted to forgotten or completely unknown in modern Lithuania the Orthodox saints St. Charitina of Lithuania († 1281) and St. Timothy Daumant († 1299).
