Any opinions or ideas about the authorship of Prometheus Bound? In my understanding of the matter: Aeschylean authorship was never questioned in ancient times, but Mark Griffith's study has provided quality statistics which seem to show that the language of the play differs significantly from the other Aeschylean works. But (and even Griffith admits this) we have only seven of Aeschylus' plays, and three of them comprise a trilogy, and are therefore likely from the same period in his career. There was an article in 2003 by H.L. Jones which argued for Aeschylean authorship, while still respecting the results of Griffith's study.
I can't offer any insights, but I'm curious to know what others think. I think it is important that the ancients seem never to have doubted its authorship, especially because they had access to many many more dramas than we do today. But the structure of the play did seem strange to me: it is very static, even if we expect it to unfold in the rest of the trilogy.
