Miller, Mitchell H., Plato's Parmenides: The Conversation of the Soul, University Park, PA: Princeton University Press, 1986.

Excerpt:

Plato’s stage-setting in the Parmenides is remarkably intricate and detailed. This is especially so in the opening pages, in which Plato provides a series of intermediary personae to introduce the conversation proper between Socrates, Zeno, and Parmenides; the structure of this series serves both to warn and to prepare us for the difficult, intensely conceptual, and critical labor of thinking through Parmenides’ hypotheses. In addition, the setting of the conversation proper is carefully established, and there is some deft, pointed characterization of Parmenides and Zeno.
