Pevear and Volokhonsky told me that they considered Nabokov’s “Onegin” one of the great triumphs of translation, even though it is nothing like their own work. Nabokov, who regarded “The Gift” and “Lolita” as his best novels, thought that his “Onegin” was perhaps the most important project of his life and, at the same time, like all translation, innately futile.
