For a while now I have been reading about Ophiuchus the snake bearer. Ophiuchus is supposedly the 13th zodiac sign. I have never read of Ophiuchus in any serious astrology book and I have never heard of an astrologer who uses it.
If Ophiuchus does exist it is the ruling sun sign during, Nov 30 to Dec 17. However this messes up all other things in the zodiac that means many people who think they are one sign may actually be another. Ophiuchus would also make it so an astrology chart shows 27.692308 degrees for every sign. 13 cannot be divided evenly into 4 and Ophiuchus would be a fire sign but that would mean 5 fire signs, and 4 of every other element.
For me the existance of Ophiuchus would mean I would be a Pisces but my qualities are much more of an Aries. I was just wondering if anyone followed this system or not.
