  The center of Proclus’ extensive oeuvre is without doubt his exegesis of Plato, as is shown by the large commentaries he devoted to major dialogues. This Platonic focus is also evident in the composition of his systematic works. The Platonic Theology offers a systematic exposition of theology based on an interpretation of all relevant sections on the gods and their attributes in Plato’s dialogues, and in particular on the Parmenides, considered as the most theological of all dialogues. Proclus probably commented on all dialogues included in the curriculum of the school since Iamblichus. In addition Proclus wrote the commentary on the Republic mentioned above. The curriculum consisted of altogether 12 dialogues distributed into two cycles. The first cycle started with Alcibiades (on self-knowledge) and ended with the Philebus (on the final cause of everything: the good), comprising two dialogues on ethics (the Gorgias and the Phaedo), two on logic (the Cratylus and the Theaetetus), two on physics (the Sophist and the Statesman), and two on theology (the Phaedrus and the Symposium). The second cycle included the two perfect dialogues that were considered to encompass Plato’s whole philosophy (In Tim. I 13.14–17), namely, the Timaeus (on physics) and the Parmenides (on theology).
