What's the origin and real meanings of the 'black zodiac'?

While browsing for zodiac information a link for the black zodiac came up (actually several). That's that movie 13 Ghosts was based off of (although the original names were changed in the movie). What the origin of this 'black zodiac' and it's meanings? Thanks in advance.|||I looked up the same thing and basically it's like your orignal horoscope (where it tells you all the good things about you) but Black Zodiac is about all the bad stuff about you. I went onto this quiz (on the link below) and I found out my black zodiac - I am originally the cancer star sign and it came up that cancer in black zodiac is a snake and is the reason that Eve ate the apple.
