[2] He was a reforming medical teacher, replacing the older curriculum based on the Articella by a new Galenism.
[4][5] His work on the Poetics is noted for its sympathy with mimesis as a poetical function, and so an opening towards classical drama[6] (the original work of Aristotle not being available at the time in Western Europe, the basis was a Latin translation by Hermannus Alemannus from Averroes, the Commentaria Media).
[7] He engaged in controversy with John of Jandun on the sensus agens, an active perceptive faculty of the soul.
[9] At the University of Montpellier he wrote also on the Ars Medicine.
[10] Some of the medical works that were attributed to him are considered to be by Bartholomew of Salerno instead.
