The Decans or Decanates:
Each sign is divided into three divisions of 10 degrees, each sign has 3 decans, one for each division of 10 degrees. Each decan has a ruler which becomes the sub ruler of the sign or the co-ruler of that sign. Once you are familiar with the Triplicities (fire, earth, air, water), it will be easier for you to determine the sub-rulers of each decan.
Each decan of a sign will be in the same triplicity (fire, earth, air, water) as the sign itself. They are arranged in the same order as they appear in the zodiac. The first decan of Aries is Aries, ruled by Mars. The second decan is Leo, ruled by the Sun, the next fire sign in the zodiac. So the second decan of Aries is ruled by the Sun. The third decan of Aries would be the next fire sign after Leo, which is Sagittarius, ruled by Jupiter. Each decan is of the same Triplicity - the fire element. The first decan of Taurus is Taurus, ruled by Venus. The second decan of Taurus is Virgo, ruled by Mercury. The third decan of Taurus is Capricorn, ruled by Saturn. Each decan is of the same Triplicity - the earth element.
