He was born at Oberehnheim near Strasbourg. In 1490 he entered the Franciscan order, and in 1495 began travelling, studying and then teaching and preaching in Freiburg-in-Breisgau, Paris, Cracow and Strasbourg itself. The emperor Maximilian I crowned him in 1505 poeta laureatus; in 1506, he was created doctor ikeologiae, and in 1513 was appointed custodian of the Franciscan monastery in Strasbourg, an office which he was forced to vacate the following year for having published a scurrilous book. Later in life, in 1518, he began the study of jurisprudence at the University of Basel, and in 1519 took the degree of doctor juris.
After journeys in Italy and England, he again settled in Strasbourg, but, disturbed by the Protestant Reformation, went into exile at Lucerne in Switzerland in 1526. In 1533 he was appointed priest of Oberehnheim, where he died in 1537, or, according to some accounts, in 1536.
Murner was an energetic and passionate character, but made enemies wherever he went. There is little human kindness in his satires, which were directed against the corruption of the times, the Reformation, and especially against Martin Luther. His most powerful satire--the most virulent German satire of the period--is Von dem grossen Lutherischen Narren wie ihn Doctor Murner beschworen hat. Others included Die Narrenbeschwörung (1512); Die Schelmenzunft (1512); Die Gäuchmatt, which treats of enamoured fools (1519), and a translation of Virgil's Aeneid (1515) dedicated to the emperor Maximilian I. Murner also wrote the humorous Chartiludium logicae (1507) and the Ludus studentum Friburgensium (1511), besides a translation of Justinian's Institutiones (1519).
