Richard III of England comes to mind, but of course Salieri has been treated badly, not in the least by the well-known movie.
What is a historical fact is that Salieri openly and explicitly prevented Mozart's career from going where Mozart wanted it to go. Mozart's talent won in the end, but Salieri did go to great lengths to try and keep Mozart from thriving. He was well-known to have placed many walls in the path of work for Mozart, and this led to the reputation he has -- a product of his own making.
Whether or not he actually killed Mozart we can never truly know. But that there is this "rumor" that he might have is only due to Salieri's own awful behavior in the treatment of Mozart.
Quotes from credible modern historians please. To my knowledge most historians think that there is no concrete evidence of this. There was just competition for jobs. Rest is drama added later.
>Whether or not he actually killed Mozart we can never truly know.
Good example of the false rumor. Salieri seems to even have confessed the murder when he was delirious but nobody believed him even then. Later he took that confession back.
This kind of thing is now a reason to accuse someone of the lowest kind of murder out of jealousy?
As for the rivalry between Salieri and Mozart, it seems that there was a short period of rivalry while Mozart was trying to establish himself in Vienna, and a longer period of amiable relations and collaboration (such as the music piece now discovered). None of this rose above the expected level (given that they had different musical styles), and it certainly doesn't make a composer who was otherwise not known to be involved in murders into a poisoner.
What are you talking about? Salieri was actually REDISCOVERED precisely because of the movie. Before the movie his legacy had gone in complete obscurity.
