From a Wall Street Journal story by Patrick Mackie headlined “Five Best: Books on Genius”:

Amadeus
By Peter Shaffer (1979)

1. It was a stroke of genius for Peter Shaffer to write a play about genius and feature at its heart a character of mediocre talent. But then the point of his Salieri is the destructive intensity with which the arrival of Mozart in 1780s Vienna exposes that mediocrity. Salieri is sickeningly aware of the tyro’s superiority; “Amadeus” also makes the older composer the most penetrating admirer of Mozart’s music all while becoming his monstrous enemy.
