Need I repeat myself, questioning truth's "quality" once more, to teach you?
If Thomas Jefferson decided to "alter" truth to protect my ancestor-hero and his legacy, if, today, at this absolutely "american literature" site, my revelations on his relations to the first three US presidents remain unchallenged, what makes you think that only "your" Mozart was "manufactured" and other truths of the era that created him were not?
Google for "abbe Raynal+Jefferson" and read (again) my last thread on "abbe Raynal-Rousseau" (it appears as #1 of 28300).
...and do try avoiding quick conclusions: If the foundations of this "house" need "strenghtening", after two centuries and a half, a good, learned, honest, architect must first be found.
(The similarities between Mozart's Bastien and Rousseau's Le Devin du Village have already been discussed elsewhere, see
