This is a new edition of Professor Dillon's 1972 collection and translation of the fragments of Iamblichus' Commentaries on the Platonic Dialogues - it benefits from the translator's amendments to his original edition gathered over the ensuing thirty-seven years of scholarly work. Facing Greek and English text, with extensive commentary by the translator. With Indices, bibliography, etc. This perhaps more than any other English language publication shows how much Iamblichus as a writer deserves to be seen in the light of what might be called mainstream late Platonic philosophy, rather than as solely a "theurgic specialist." This is the first volume of a new Series entitled, "Platonic Texts and Translations"
