Kogo na sejmie lubelskim reprezentował Augustyn Rotundus Mieleski († 1582), wójt wileński i sekretarz królewski

ENThe Vogt of Vilnius, Royal Secretary Augustinus Rotundus (the Rotund, Mieleski) was present at the Sejm of Lublin in 1569 at the initiative of the Lithuanian Chancellor and Vilnius Voivode Mikołaj "the Red" Radziwiłł. He participated in the Sejm as the Royal Secretary and Counsellor of the Lithuanian delegation, as well as a renowned historian and an experienced lawyer. Rotundus remained in close relations with the Radriwills, perhaps even as a cliens. Likewise, in his capacity of notary public, Rotundus was the proxy of the Bishop of Vilnius Walerian Protasewicz. Thus, the Vogt of Vilnius was not a member of the Lithuanian delegation or a representative of the city of Vilnius. He could not be the latter due to the specificity of the office of the vogt - until the beginning of the 17th century the vogt of Vilnius was not elected by the magistrate; he was the king’s representative in the city. As a Royal Secretary, harbouring aspirations to nobility, Rotundus (originating from a bourgeois family in Wieluń) did not want to be identified with the city. Nevertheless, Rotundus has served Vilnius well through his behind-the-scenes activities to the benefit of the city.
