Yanni, believe it or not there are many people who do NOT know that the manufactured career of W.A. Mozart is a plain, verifiable fact. And since they require more than games with multiple personalities and aliases that is what is the priority. But you are free to make a thread of your own on that subject. At any time. This thread is on Mozart, and it is dealing with the music that is attributed to him from the time of his first tour to Italy. On which you (and anyone else) can see documentary and other evidence.
If you wish to provide us with evidence of multiple aliases please do so. Nobody has ever stopped you.
I am well aware of Cowper's relationship to Britain and to the Holy Roman Empire. More than you may realise. (He became an aristocrat of the Holy Roman Empire himself and almost never visited England after his arrival in Italy). And I am well aware of Walpole's correspondence with Horace Mann.
If you wish to tell us about H. Walpole's letter to Horace Mann of 29th May 1786 please do so. Especially if it relates to Mozart and 1770.
What I wish to know is why you don't tell us ? So that we can all see it for ourselves.
