Tutor
Having studied at Ingolstadt, Vienna, Cracow and Paris, he returned to Ingolstadt in 1507 and in 1509 was appointed tutor to Louis and Ernest, the two younger brothers of William IV, Duke of Bavaria, all three the sons of Albert the Wise, the late duke of Bavaria. Aventinus retained this position until 1517, wrote a Latin grammar (Rudimenta grammaticae latinae; 1512) and other manuals for the use of his pupils, and in 1515 travelled in Italy with Ernest. In his zeal for learning, he helped found the Sodalitas litteraria Angilostadensis, the "literary brotherhood of Inmgolstadt", under the auspices of which several old manuscripts were brought to light; however, it soon ceased to exist (1520).
