One question on the story: What ever happens to Olga?
Pushkin spends a couple of stanzas on that - she quickly gets over her loss, marries a military man, and leaves to live with him at a military base.
Oh, found it on
Here
BTW, I can't believe how awful the translation is; it conveys nothing of the light and playful nature of Pushkin's writing. Edited to add - OK, I see now, this is the infamous Nabokov translation - extremely accurate and basically unreadable.
I am very ambiguous about Tchaikovsky's Pushkin operas. I do, of course, have to admit - I understand nothing about opera, not too much about music, while I love and understand Pushkin's poetry. My main problem with Tchaikovsky's operas is that the librettos (written by his brother) are overly sentimental. This is especially true of "Queen of Spades" - in the opera, Lisa drowns herself form sorrow, whereas Pushkin had her get over her grief quickly and get married. Pushkin's version is more cynical and more true-to-life; unfortunately, many people (even in Russia, let alone abroad!) only know the opera version. In Tchaikovsky's interpretation of Onegin, I think Lenski is seriously mis-represented. It was popular back then (and, truthfully, still is) to draw parallels between Lenski and Pushkin himself - both poets, killed young on duels over women. IMO, this is absurd. Pushkin never saw Lenski as anything resembling himself! Sure, he didn't take himself too seriously, but he took Lenski even less serious than that. Just take a look
Here - stanza 38 (39). BTW, this translation is much better. Anyway, Pushkin made Lenski into a cliche on purpose; I certainly don't think he saw himself as such.
Anyway, I don't really have any opinion on the opera itself - only the libretto.
Edited to add one more thing - if you have time, buy yourself a copy of Onegin - the Oxford edition translation is very decent. I am sure you will enjoy it. Pushkin had that mix of cynicism and love for his characters that I am sure you will like. Just please - don't base any opinions of Pushkin on the operas.
