JENZENSTEIN (JENSTJEN), JANA of. – Archbishop of Prague, b. 1350, d. 1400. After studies completed at Padua, Bologna, and Paris (1370–75), J. became in 1376 Bishop of Meissen and in 1378 succeeded his uncle Cardinal Giovanni Očko of Vlašim on the archiepiscopal see of Prague.
J. supported the Roman Popes (Urban VI, Boniface IX) against the Avignonese claimants and also induced King Wenceslaus IV, of whom he was chancellor from 1380–84, to do the same. He vigorously opposed any interference by laymen in the sphere of his archiepiscopal jurisdiction. Because of this, J. frequently clashed with King Wenceslaus, most acutely in 1393, which cost the life of his vicar general St. John Nepomucene (v.). In 1396 J. abdicated in favor of his nephew Wolfram of Skvorec and retired to Rome, where he died as titular Patriarch of Alexandria and was buried at S. Prassede. Besides some relics, he left behind theological treatises, especially on the Visitation of the Blessed Virgin Mary, whose feast he introduced into his diocese. While living in the monastery of S. Prassede, he revised and corrected his works, the original manuscript of which is preserved in cod. Vat. lat. 1122.
