[3][5] After the early death of his father, Augustinus grew up in the household of his uncle Andreas Ctiborius, who was canon at Olomouc.
[6] Sponsored by Ctiborius and Johann Roth (1426–1506), Bishop of Wrocław, Augustinus studied at the Jagiellonian University at Kraków from 1484 to 1488,[7] where he was graduated as a magister of philosophy[5] and then at Padova.
[9] Augustinus was a stout opponent of the Moravian Church (Waldensians), and in his position at the chancellery he influenced the king to massive repressions against these, in the spirit of Heinrich Institoris.
[9] Augustinus maintained intensive contacts with other humanists of his time, and was also a member of Conrad Celtis' Sodalitas Litterarum Danubiana in Vienna.
[7][11] Augustin offered generous support to fellow humanists, such as to Valentin Eck,[12] whom he housed for some time, or to Johannes Cuspinian, whom he let peruse his large library, or to Celtis and Joachim Vadian, whom he sent copies of manuscripts they otherwise had no access to.
