Astrology to the novice can seem quite confusing and overly complicated, this is because there are several different methods. While the approach to Decanates and Rulership in each of the methods remains much the same, the Decanates themselves are different. In the above chart, (from the outer, working inward) for each sign an element is assigned. If we look at Aries we can see it has a fire sign, it is assigned the numbers 1,2 and 3 because Aries is the first sign and the Horoscope begins here. Aries is Ruled by Mars and the three Decanates are Mars, the Sun and Venus. If we now move to Taurus, the second astrological sign we see that Taurus is assigned an Earth symbol, numbers 4, 5, and 6 and has Mercury, the Moon and Saturn assigned as Decanates. In the Chaldean Method, the Rulers of the Decanates follow the order of the Chaldean Planetary Order which were derived from the geo-centric speeds of the Planets, they are: Saturn - Jupiter - Mars - Sun - Venus - Mercury – Moon. This order is followed from the first Decanate to the thirty sixth and final Decanate in Pisces.
