re: it being Odysseus' idea in The Trojan Women: right you are. Incidentally, "no survival for even an infant prince of Troy" reminds me that Virgil had to do some retconning to explain the survival of Aeneas and son in classic fanfiction fashion...

I once saw The Trojan Women staged at Salzburg, by a Romanian ensemble, performing in their language. Very powerful experience, despite this being before the age of subtitles; the acting was this good.
