His writings, consisting of short poems, philosophical essays, grammatical notes and letters, were published after his death by his pupil Jacob Faber.
Here he came under the influence of Jacobus Faber (Stapulensis), on whose recommendation he was appointed professor in the college of Cardinal Lemoine.

He won over the Savoyard Pierre Lefevre (Faber), whose room he shared, and the Navarrese Francis Xavier, who taught philosophy in the college of St Barbara.
