ENDuring the second half of the 15th and 16th centuries in Chancellery of the Grand Duchy of Lithuania as Tatar scribers and interpreters worked about twenty members of the Juszinski’s duke clan. It’s approximately half of the Tatar scribers and interpreters directly related to the Vilna Chancellery, from whom we can identify today, based on the sources’ state. Language competence, capacity for translation and simultaneous interpretation, diplomatic talents and intelligence skills formed the basis of the cultural fund of the Family, which the Juszinski dukes transformed into the economic, social, and sometimes even in political capital with great success. The cultural values were handed down for at least five generations. [From the publication]
