„Wagner exploited all forms of expression at a composer's disposal -- harmony, dynamics, orchestration -- to the extreme. His music is highly emotional, and at the same time Wagner has extraordinary control over the effect he achieves. That's why there is also something manipulative about Wagner's music, which is not to say that it's not honest. In fact, I believe that it's totally honest, but it also happens to be manipulative.“

To Leon Goldensohn, February 12, 1946, from "The Nuremberg Interviews" by Leon Goldensohn, Robert Gellately - History - 2004

Original text:
Tutti gli innovatori sono stati logicamente futuristi, in relazione ai loro tempi. Palestrina avrebbe giudicato pazzo Bach, e così Bach avrebbe giudicato Beethoven, e così Beethoven avrebbe giudicato Wagner.
Rossini si vantava di aver finalmente capito la musica di Wagner leggendola a rovescio! Verdi, dopo un’audizione dell’ouverture del Tannhäuser, in una lettera a un suo amico chiamava Wagner matto.
Siamo dunque alla finestra di un manicomio glorioso, mentre dichiariamo, senza esitare, che il contrappunto e la fuga, ancor oggi considerati come il ramo più importante dell’insegnamento musicale...

Kontext: They say I was the greatest natural hitter of all time. Well that's saying a lot with hitters like Wagner, Cobb, Speaker and Ruth around. I had good eyes and I guess that was the reason I hit as well as I did. I still don't use glasses today.

Jitterbug Perfume (1984)

But I [Renoir] was very happy it wasn't too much of a flop: There is something of that admirable face in it'
Quote of Renoir, in his letter to a friend, 15 Jan. 1882; as cited in 'Pierre Auguste Renoir - Richard Wagner', text of museum D'Orsay http://www.musee-orsay.fr/en/collections/works-in-focus/search/commentaire/commentaire_id/richard-wagner-11042.html?no_cache=1
At the beginning of 1882, Renoir was travelling in the south of Italy and visited Palermo where Wagner was staying. Renoir proposed a short sitting for the following day and Wagner agreed; he had just finished his 'Parsifal'.
