In a classic New Republic essay from 1941, Vladimir Nabokov expounds on the necessary qualities of the good translator:
We can deduce now the requirements that a translator must possess in order to be able to give an ideal version of a foreign masterpiece. First of all he must have as much talent, or at least the same kind of talent, as the author he chooses. In this, though only in this, respect Baudelaire and Poe or Joukovsky and Schiller made ideal playmates. Second, he must know thoroughly the two nations and the two languages involved and be perfectly acquainted with all details relating to his author’s manner and methods; also, with the social background of words, their fashions, history and period associations. This leads to the third point: while having genius and knowledge he must possess the gift of mimicry and be able to act, as it were, the real author’s part by impersonating his tricks of demeanor and speech, his ways and his mind, with the utmost degree of verisimilitude.
What not to do:
The … sin of leaving out tricky passages is still excusable when the translator is baffled by them himself; but how contemptible is the smug person who, although quite understanding the sense, fears it might stump a dunce or debauch a dauphin! Instead of blissfully nestling in the arms of the great writer, he keeps worrying about the little reader playing in a corner with something dangerous or unclean. Perhaps the most charming example of Victorian modesty that has ever come my way was in an early English translation of “Anna Karenina.” Vronsky had asked Anna what was the matter with her. “I am beremenna” (the translator’s italics), replied Anna, making the foreign reader wonder what strange and awful Oriental disease that was; all because the translator thought that “I am pregnant” might shock some pure soul, and that a good idea would be to leave the Russian just as it stood.
