Piotr Dunin Wolski

[1] He was the son of Paweł Dunin-Wolski, the grand crown chancellor, the Poznań bishop (1544-1546) and Dorota Wiewiecka h. Jastrzębiec.

After returning from Italy, he stayed at the court of King Zygmunt August, where he became known as a man especially talented for foreign languages and for service in diplomacy.

After returning to Poland, he was again sent to Spain after the death of Piotr Barzego, the castellan of Przemyśl and a Polish deputy who made wrong decisions in state matters, which required immediate intervention and repair.

Shortly thereafter, he submitted the chancellor's seal to Jan Zamoyski, and having not yet approved the papacy for the diocese of Przemyśl, he was nominated for the bishopric in Płock, where his rule lasted from 5 July 1577 until his death on 28 August 1590.

Accumulated books were donated by the Kraków Academy (about 1000 volumes) and the library of the Płock chapter (130 works).
