The fourth conference of the Avicenna Study Group (ASG) was organised this year by Olga Lizzini (Aix-Marseille Université/CNRS-Iremam) and Andreas Lammer (Radboud University Nijmegen) in Aix-en-Provence. During the three-day event (13-15 September), papers focused on the minor treatises of the famous philosopher, Avicenna (d. 1037). Furthermore, the participants agreed on the new research programme of the research group for the coming years. Our colleague István Lánczky represented our institute at the event.
