Exegetical work on philosophical systems requires not only that one give an account of the structure of a system’s assumptions and arguments, but also of its forms, such as the form of expression (or genre: dialogue, poem, aphorisms, and so on), or its form of argumentation (clear cut dis- cursive exposition, logical formalization, metaphorical, allegorical discourse, and so forth). These formal considerations may seem to be secondary, merely ornamental issues, but they can raise unexpected questions. The literal reading of a (...) text has its counter-part in allegorical interpretation. This way of reading, which must have started with the first readers of Homer and found a fertile ground in Philo’s allegorical commentaries on the Bible, was amazingly natural for Proclus (c. 411– 485), whose writings and commentaries represent the last phases of late antique philosophy, and particularly of the relation between philosophy and rhetoric.
