The article analyzes the punctuation in the Life of St. John of Rila by Patriarch Euftimius according to the earliest copy in the so-called Zografski Sbornik (No. 172, 14th century, monastery St George, Mount Athos). By comparison with certain earlier and later texts, several features stand out - punctuation has strictly distinguishing functions and the dots in the line separate phrases longer than in other manuscripts. This construction agrees quite well with the ancient theory of ‘period’, as it is divided into ‘kolons’ by commas and dots in the row, and the middle point graphically means its end.
