Reading his textbook, his extracts of Parmenides are much more readable than the other translations I've come across, but he only seems to source them by Diels-Kratz number!
In case anyone recognises the translation of these extracts they are:
What you can call and think must Being be For Being can, and nothing cannot, be
Never shall this prevail, that Unbeing is; Rein in your mind from any thought like this.
Unbeing you won’t grasp—it can’t be done— Nor utter; being thought and being are one.
