I have serious reservations about harry potters' books. One could read it but for the depth of incantations and voodoo/magic involved.
Yes, Yes it is fiction, but one wonders whether those things written about in such detail are sincerely the figment of the writers imagination!
They're not. Rowling has admitted in interviews that she's done a great deal of research into historical beliefs about magic, and that a fair portion of that has ended up in her works. I think the minimum estimate was something like a third of the stuff in the books was believed to be real at some point...and how do we know it isn't?
