Goodreads shoves all the different translations of Medea into a single entry, apparently. THIS one has some very interesting introductory text, but the text (including when quoted in introduction and the entire commentary) is written entirely in Greek.
Had fun, learned a little Greek spelling, especially loved the part where it said, basically, "someone made an argument for x, but I think that so-and-so refutes it well in their essay so I don't need to talk about why it's wrong here." I haven't the foggiest idea what the controversy was.
Great obscure book for the Greek scholar in your life, perhaps.
