He was born on 6 September 1597 in
Győr. He was the son of a Feldzeugmeister and Hofkriegsrates from the Austrian noble family Breuner. From 1617 to 1621 he studied in the
Collegium Germanicum at the
Pontifical Gregorian University in
Rome and graduated with a doctorate. On 8 December 1621, he was ordained a priest in Nikolsburg and was appointed on 9 September 1630 auxiliary bishop in Olomouc and titular bishop of Ioppe. The episcopal ordination was received on 5 September 1635. He was also a canon in
Olomouc,
Wrocław and
Regensburg, and Provost in
Brno. Emperor
Ferdinand III appointed him Prince-Bishop of Vienna on 5 May 1639,
Pope Urban VIII confirmed it on 5 September 1639. On 26 December 1639, he was installed in
St. Stephen's Cathedral. He is described as a pious bishop, concerned with pastoral care and the preaching activity of priests. For the growing suburbs of Vienna, he redefined the parish boundaries. He was able to complete in 1641 the new building of the Episcopal Palace, begun by Prince-Bishop Anton Wolfradt in 1632 according to the plans of
Giovanni Coccapani. The Prince-Bishop erected the monumental high altar in St. Stephen's Cathedral and concluded a contract with the stonemason and sculptor Johann Jacob Pock from Constance on 1 March 1641. His first master builder was Simon Humpeller, followed by Hans Herstorffer in 1641, followed by Adam Haresleben in 1654. The large altarpiece was painted by
Tobias Pock, brother of the sculptor. After some delays, he was able to solemnly dedicate this work on 19 May 1647. His marble coat of arms was attached to the altar, and he also had the new cathedral stalls carved. On 18 May 1647, he consecrated the column, crowned by the statue of the
Immaculate Conception in front of the church on the courtyard (model of the Marian Column of Munich in front of the town hall). Emperor Ferdinand III resolved to celebrate the feast of the Immaculata Conceptio on 8 December in his dominions. Prince-Bishop Breuner died on 22 May 1669 in
Vienna. He is buried in the women's choir of St. Stephen's Cathedral in Vienna. ==References==
