The names and identities of these twelve elements vary between different zodiacs. In Western astrology, they are of the Aries-Pisces range; in Eastern astrology, they are typically of the Rat-Pig range. One thing does hold in common for both interpretations, however: Every alternating fourth sign is said to be compatible and of the same zodiacal element (or tribune, in the Chinese zodiac), while every alternating sixth sign (that is, polar opposites of the geometric circle) are said to have a more unique relationship (normally explained as bad or poor).
