Native German speaker here and I find the way Zeitgeist is used in English strange sometimes. I feel the word is often used synonymous to fashion or for "things currently popular" in English. A good example is Google's Zeitgeist which gives the popular searches for just one year. This is not something we would call Zeitgeist in German, I think.

In German we would say "Goethe captured the Zeitgeist of his epoch", on the other hand saying "Dark rimmed glass are in the Zeitgeist" would be strange.
