  The interpretation of the Parmenides thus prepares the way for the Platonic Theology, offering the systematic structure for a scientific demonstration of the procession of all the orders of gods from the first principle. As Proclus explains at Theol. Plat. I 2, p. 9.8–19, the Platonic Theology falls into three parts (after a long methodological introduction). The first part (Theol. Plat. I 13–29) is an investigation into the common notions (koinai ennoiai) of the gods as we find them in Plato’s dialogues: it is a treatise on the divine names and attributes. The second part (Theol. Plat. II–VI), which is incomplete, unfolds in a systematic way the procession of the divine hierarchies, from the One, that is the first god, to the ‘higher kinds,’ i.e., angels, daimones, and heroes, while the third part, which is altogether missing, was supposed to deal with the individual hypercosmic and encosmic gods.
