why has Myshkin been called an idealized version of Don Quixote?

[Don Incognito]

I saw that quotation once. When I read this book seven or eight years ago, I never picked that up. I don't see the similarity.

Although I must admit that I haven't read Don Quixote (I know! I hope to read it this year!), from what I've read second-hand about the character, both Don Quixote and Myshkin seem to have unrelenting faith (although that term might be redundant). Although they have faith in different things, as I'm pretty sure Don Quixote is not a Christian or at least is not in service of relaying Christian values like Myshkin is, in each respective book their commitment to each is so extreme that outsiders, at least in the novels, see them as comically irrational.
