The star is the ancient Sumerian symbol for divinity and the stars that filled the skies in that part of the world were the real founders of astrology. In their records that still survive we find the idea that planets represented gods. The writings show that these gods had the power to intervene or direct. Mercury was considered a quick, cunning, bisexual god, with calculating wisdom. Jupiter was a ruler of men and considered regal and Saturn thought of as quick tempered and cruel. As these descriptions took hold so too evolved the basis of astrological lore.
