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'.
