Paisius was a monk who gathered accounts of rulers, saints and the Bulgarian past. He wrote to persuade readers to know their language and history. The book combines older sources with its author’s position; it is not a modern research textbook. Hand copying brought it to readers far from its place of creation. Completed Slav-Bulgarian History in 1762. Worked within the monastic world of Athos. The text circulated through handwritten copies. The history of its copies shows how one book became a public event.
