I read "Mozart and Salieri" in Russian*, and considered the the Salieri film, which achieved some fame, plagiarism. Pushkin begins with Salieri's provocative monolog, 2pp, on his happiness hearing music as a child, the church organ even brought tears, then studying under "old Gluck," working very hard, enjoying his friends' advancement.
As he began writing in secret, Звуки умертвив / музыку я разъял, как труп. Killing the sound, I split open music like a corpse (39). "I was happy, until the holy gift, the deathless genius, without hard work, little paid, without feverish intent, came into the mind of a reveller who listens to fiddlers in bars. O Mozart!"
Whereupon Mozart enters, bringing the bar fiddler, but also filled with respect for Salieri, tells him he's a god, too.
Last of the four short plays, Pushkin translates from John Wilson play on plague (1816) titling his, "The Feast during the Plague," focusing on the best part of the English, and also turning Walsingham, Master of the Revels, into the hero. The main interlocutor is a priest, but at the end a woman's voice in the next room shouts, "He's crazy, he raves about burying his wife." The priest leaves the feast with Walsingham, asking God to forgive "my son."
