Salieri was incensed that God would bless so vulgar and obnoxious a young snipe as Mozart with divine genius. Why was Salieri -- so disciplined, so devoted to his art, and so willing to toady to his superiors -- not touched by God? Unable to match Mozart's talent, Salieri uses his influence in court to sabotage the young upstart's career. Disguising himself as a mysterious benefactor, Salieri commissions the backbreaking Requiem, which eventually costs Mozart his health, wealth, and life.
