  In his Proclus Commentary, Joane Petrizi analyses the dialectic hidden in the ‘cause’ and the ‘caused’ more thoroughly and in more detail than does Proclus himself in the corresponding chapters of his Elementatio theologica. In Petrizi’s exegesis, the abstract, mathematical style of this work is augmented in content with a wealth of material. Petrizi operates very often with visually illustrative examples, and is careful to illuminate the theorems set forth in the Elementatio theologica by means of human experience. This resulted from the goals of his Interpretation. It primarily addressed a broad public and served the study of this significant work from Greek antiquity.
