Yes, worth reading. Not much on lexical semantics however. Aeschylus gets faulted for using known words in unknown ways but on several occasions I have seen Pindar listed in LSJ under the same gloss with Aeschylus and no one else. While we always need to use LSJ with caution, there seems to be some basis for claiming that Aeschylus was not always alone when he employed a known word in an unusual manner. As far as Aristophanes criticism goes to find fault with Aeschylus' word choice, one should keep in mind that lexical semantics never stands still. English usage of fifty years ago is now archaic.
