As Helmut Keipert (2001) has shown, the anonymous and undated manuscript titled Rozmova and Besěda (which linguists so far wrongly attributed to the end of the 16th century) is also an autograph by Ivan Uzhevych.
The manuscript was published in a scholarly edition in 2005 together with the Latin original from 1613 and a translation of the same text into Polish from a print of 1646.
