Then, the young Mozart came along. He was 14. Listening to the Misere in the Sistine Chapel, he later wrote out the entire score from memory. As everybody now knows, Mozart's memories were extraordinary. Mozart had only to make minor corrections on a second visit to the Chapel. It would have been impossible for anybody else to accomplish this feat.
Through the genius of Mozart, the mysterious music of the Vatican was now out in the world. The Pope, after Mozart was summoned to Rome for investigation, praised his musical genius, instead of excommunicating the charming fellow.
Pondering the significance of this famous episode, I wonder if all creative genius is not like it. Bringing to the world a marvelous gem hidden jealously in some obscure corner of the world, only to be experienced by those who were fortunate enough to be in that location by chance. Genius is about highly strung sensitivities and prodigious memories.

Misere of Gregorio Allegri. Made open by the service of Mozart.
