To make up for last week's absence, we're going for two quizzes today. Here's how it'll go: when we get the correct answer to part one (below), I'll post the second question, and we'll play that one out in a new string of comments? Exciting? Of course not. But it's all I have to offer. Anyway, here's part one:

Estimates of the number of worshippers in this religion range between 100,000-800,000. According to its doctrines, the most powerful angel in heaven rebelled and was cast out for his transgression. Repenting, in the form of a peacock he re-created the world. He also quenched the fires of Hell with his tears. Holy texts include the "Book of Revelation" and the "Black Book." The latter forbids lettuce, certain beans, and the wearing of dark blue. The holy day is Wednesday; practitioners do not bathe on Wednesday evenings, so as to preserve water for the dead, who use that day for washing.They have been accused of being "devil-worshippers" by adherents of other religions --although aspects of these other religions are incorporated into their doctrines. Some details about the religion (accurate or otherwise) have informed the writings of H. P. Lovecraft and Alan Moore.

Adherents of this religion belong exclusively to one ethnic group, although they make up a very small minority within that group.

To what ethnic group do these worshippers belong? For super-bonus points, name the religion itself.

The first correct answer posted to comments wins a box of Sun Maid's new Crunky Craisins(TM) -- "The Healthy Snack from the Dirty South." No Googling or digging out The Golden Bough. One guess per comment, but comment as often as the peacock angel moves you.
