how his intercourse with the Devil commenced almost accidentally and
against his intentions:--

"I, Doctor Johann Faust, who apply myself to the Free Arts, having read
many kinds of books from my youth, happened once to light upon a book
that contained various conjurations of the spirits. Feeling some desire
