for star sign compatibility with the person you love has become a common practice powered by the multiple columns you find in all sorts of magazines about the importance to make great zodiac matches. In ancient cultures the determination of astrological compatibility was a serious task that relied on the interpretation of cosmic facts and events. Thus, every person is born under a star sign and all his/her life unfolds in close connection with the cosmic energy of the moment of birth. According to the Chinese interpretation, compatibility involves the study of the basic elements: water, air, fire and earth.
