Saint Sophronius of Vratsa (1739–1813), a Bulgarian bishop and disciple of the Venerable Paisius of Hilandar, is regarded as the founder of literature and printing in the modern Bulgarian language, through his book of sermons and moral teachings, Kiriakodromion, printed in Râmnicu-Vâlcea in 1806. His spiritual, educational and philanthropic work made a decisive contribution to the Bulgarian Renaissance, to the education of the clergy and the people, and to paving the way for the struggle for an autonomous Bulgarian Orthodox Church.
