This volume is the first edition of Petrus de Alvernia's Sententia super librum 'De vegetabilibus et plantis'. The treatise 'De vegetabilibus et plantis', which goes back to the Peripatetic Nicolaus of Damascus and has an interesting tradition (from Greek into Syrian, from Syrian into Arabic, from Arabic into Latin), was considered to be a work of Aristotle's and was among the subjects prescribed for study in the Facultas Artium in Paris. Petrus de Alvernia's Sententia should primarily be regarded as an exposition of this often problematic work for the students of this faculty.
