I really can&#x27;t tell for certain, but I feel fortunate that Michael Kandel translated Stanislaw Lem&#x27;s works; they read so well to me, I can&#x27;t imagine them not being what the author meant. The fact that the poetry in &quot;Cyberiad&quot; works so well (in English) makes me feel he&#x27;s a good and honest translator. You&#x27;re right on Eco, though: I can&#x27;t name the translator for Pendulum.
