Rowling has also written "Fantastic Beasts and Where to Find Them", a guide to the magical beasts found in the series.  Many of these are derived from folklore, primarily Greek mythology, but also British and Scandinavian folklore.  Many of the legends surrounding mythical creatures are also incorporated in the books.  "Children ... know that I didn't invent unicorns, but I've had to explain frequently that I didn't actually invent hippogriffs," Rowling told Stephen Fry in an interview for BBC Radio 4.  "When I do use a creature that I know is a mythological entity, I like to find out as much as I can about it.  I might not use it, but to make it as consistent as I feel is good for my plot."
