In Dostoevsky's original notes, Prince Myshkin wasn't a figure of Incorruptible Pure Pureness, but a proud and passionate villain who would have undergone a complete regeneration by the novel's end.
At the time Dostoevsky finished Part One, he was still planning on a very different ending in which Myshkin would redeem both Nastasya and Rogozhin.
Write What You Know: Myshkins epilepsy, his reaction to Hans Holbein the Youngers painting Christs Body in the Tomb, his thoughts on Catholicism: all modeled on Dostoyevkys own thoughts and experiences. Myshkin recounts via hearsay the thoughts of a condemned criminal awaiting execution; Dostoyevsky had himself been condemned, run through a mock execution, and only informed at the last second that his sentence had been reduced.
For the album:
Black Sheep Hit: The album as a whole is considered this for Iggy Pop. While it sold well and has received plenty of critical acclaim over the years, the general consensus is that it is very much unrepresentative of Pop's sound, especially compared to his later solo albums. This is mainly due to the fact that the album was produced by David Bowie, whose work as a producer typically features him adding in prominent elements of his own musical style, The Idiot being no exception.
