We discuss Proclus' titanic labours in the field of commentary – on many Platonic dialogues, but also on the Chaldæan Oracles, the Homeric poems, and a number of other texts – with Graeme Miles, an acute reader of Platonist philosophy and part of the team translating Proclus' Republic commentary into English. Come for Platonic commentary as spiritual practice, stay for the kosmic-astrological reading of the Myth of Er.
