Area which the Sun transits on average between October 23 and November 22 each year, linked to the constellation of Scorpius. In Ancient Egypt, Scorpio was the equivalent of the Serpent.[2] Serpents were worshiped by ancient Egyptians. In Egypt not only are there serpents of the houses, but each quarter in Cairo had a serpent-guardian (Lane).[3] Before the discovery of Pluto in 1930, the planetary ruler of Scorpio was Mars, but modern astrologers tend to use Pluto as the sole ruler.
