Career
He served as crown deputy chancellor from 1472, bishop of Kuyavia from 1472, and bishop of Gniezno and primate of Poland from 12 October 1481. During the absence of King Casimir IV Jagiellon he was deputized in several state matters including dealing with the Prussians. However, by the end of Casimirs reign their relationship had soured, probably due to a rivalry with Fryderyk Jagiellończyk, the Bishop of Krakow and Casimir’s relative.
After the death of Casimir, he was a strong supporter for the election of Janusz III of Masovia to be the new king.
He died 2 February 1493, in Łowicz, and was buried in the Cathedral of Gniezno, where his tomb was built with red marble by Veit Stoss.
