The Chart Ruler Complex
Planets as Chart Rulers
Definition
The chart ruler is the planet which rules the sign on the Ascendant.
As the Earth rotates every planet gets to rule a chart as its own sign takes up the Ascendant position.
When a particular sign is on the Ascendant, we can see that the signs will be on the other house cusps in sequence.
Each sign lies on a house cusp in order but not if there are intercepted signs see below.
Chart Planetary Ruler
Note: If there are two chart rulers, each one will be interpreted separately.
Sign Rulers
Planets Ruling the Signs
Each sign has a planet that rules the sign.
This planet is known as the sign ruler.
Most planets rule two signs except the Sun and Moon which only rule one sign each.
Additionally, three signs have two rulers.
Traditional Rulers
The traditional or visible planets are the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn.
The traditional rulers are:
Aries – Mars
Taurus – Venus
Gemini – Mercury
Cancer – Moon
Leo – Sun
Virgo – Mercury
Libra – Venus
Scorpio – Mars
Sagittarius – Jupiter
Capricorn – Saturn
Aquarius – Saturn
Pisces – Jupiter
Modern Rulers
When the three outer planets Uranus, Neptune and Pluto were discovered they were allocated to three signs.
The modern rulers are:
Scorpio – Pluto
Aquarius – Uranus
Pisces – Neptune
Chart Overlay
A chart overlay will indicate that certain signs will be on the house cusps and we can discuss them in relation to the chart ruler.
When the chart ruler is in the different houses its drive is modified in line with the house.
Very often the meaning of this planet by its placement and complex is the main thrust of a person’s life.
Intercepted Signs
House Systems
If you use Placidus cusps, or some of the other house systems, you may have an intercepted sign.
An intercepted sign is a sign that is fully engulfed in a house.
The intercepted sign will not lie over a house cusp.
An intercepted sign’s planetary ruler, (the planet that rules the sign), may not have a house to rule.
This makes the planet weaker.
Intercepted signs come in pairs which are opposite each other in the chart.
There will either be two intercepted signs or none.
House Rulers
House Cusps
Always check which sign is on the cusp of each house and adjust your interpretations accordingly.
For example, if Libra has no house cusp, then typically Scorpio may have two house cusps in a row.
David Bowie
Virgo and Pisces Intercepted
In the birth chart for David Bowie shown below, he has Virgo and Pisces as intercepted signs.
Note that his intercepted signs are a pair of opposite signs.
Virgo Intercepted
The sign of Virgo is not on any house cusp.
Mercury, the ruler of Virgo, has no Virgo house to rule.
However, Mercury still rules the 4th and 5th houses through its rulership of Gemini and therefore has some influence house-wise.
Pisces Intercepted
The sign of Pisces is not on any house cusp.
Jupiter does not rule any Pisces houses as Pisces is not on any house cusp.
Although Jupiter does have two houses to rule which are the 10th and 11th houses with have Sagittarius, Jupiter’s traditional sign, on the cusp.
However, Neptune, the modern ruler of Pisces, has no house to rule because it only rules Pisces, and therefore has no influence house-wise in Bowie’s chart.
This makes Neptune slightly weaker in his chart.
Consecutive Houses Same Sign
Double Tap
In Bowie’s birth chart, the signs of Gemini and Sagittarius (opposite pairs) are on two consecutive houses.
Gemini Cusps
Gemini is on the 5th and 6th houses and so Mercury rules the Gemini houses (and not the Virgo houses because there are none).
Sagittarius Cusps
Sagittarius is on the 10th and 11th houses.
This indicates that Jupiter has more influence through Sagittarius being on two house cusps.
Luminaries Signs Intercepted
Sun and Moon
If the intercepted sign is Cancer or Leo, it means that the Moon or the Sun do not have houses to rule.
This makes them weaker which is unfortunate, but typically another planet will step forward as the most influential in the chart.
Sylvester Stallone
Cancer and Capricorn Intercepted
In the birth chart for Sylvester Stallone shown below, it has Cancer and Capricorn as intercepted signs.
Note the intercepted signs are a pair of opposite signs.
Cancer Intercepted
The Moon as the ruler of Cancer has no house to rule!
This make the Moon weaker in this chart.
Additionally, all planets in Cancer (the intercepted sign), that is the Sun and Saturn, will take a step backwards as well and they will struggle to be prominent in his chart both natally and by transit.
By the way, the Moon is the most elevated planet (nearest to the Midheaven), so this is a slightly redeeming factor for the Moon.
Capricorn Intercepted
Saturn the ruler of Capricorn, as the traditional ruler of Aquarius still rules the 2nd house.
So Saturn does have a house to rule but not through Capricorn only through Aquarius.
Consecutive Houses Same Sign
In Stallone’s birth chart, the signs of Gemini and Sagittarius (opposite pairs) are on two consecutive houses.
Gemini is on the 6th and 7th house cusps and Sagittarius is on the 1st and 12th house cusps.
This indicates that both Mercury and Jupiter will have influence through Gemini and Sagittarius.

Now let’s look at each planet as the chart ruler.
Many planets have two distinct styles of expression as the chart ruler because they rule two different signs.
