Houses in Astrology

What are the houses in astrology?

The houses are the twelve sectors of a birth chart, each describing one area of life and calculated for the time and place of birth. In Placidus the first house begins at the ascendant degree on the eastern horizon; in whole-sign houses it covers the entire rising sign. The count runs counter-clockwise around the wheel from the first house to the twelfth.

Houses are easy to confuse with signs, but they come from different movements. The twelve signs divide the Sun’s yearly path, so everyone born in the same few weeks shares a Sun sign. The twelve houses divide the local sky as the Earth turns each day, so they change with the hour and the town. In a chart, a planet is the actor, its sign is the way it plays the part, and its house is the stage. Venus in Taurus in the second house brings a Taurus taste for comfort to money and possessions; the same Venus in the seventh house brings it to partnership.

House	Area of life	Type	Natural sign
1st house	self, body, approach to life	angular	Aries
2nd house	money, possessions, self-worth	succedent	Taurus
3rd house	siblings, communication, short trips	cadent	Gemini
4th house	home, family, roots	angular	Cancer
5th house	creativity, romance, children, play	succedent	Leo
6th house	daily work, routines, service	cadent	Virgo
7th house	partnership, marriage, open rivals	angular	Libra
8th house	shared resources, intimacy, endings	succedent	Scorpio
9th house	beliefs, higher study, long journeys	cadent	Sagittarius
10th house	career, reputation, public role	angular	Capricorn
11th house	friends, groups, hopes	succedent	Aquarius
12th house	retreat, the hidden, inner life	cadent	Pisces

The type column matters. In quadrant systems, angular houses begin at the four angles: ascendant, IC, descendant and Midheaven. They describe prominent areas of experience. The table’s natural signs are a modern sign-house analogy, not the signs on your own house cusps. Succedent houses follow them and hold what the angles start: money, children, shared resources, allies. Cadent houses “fall away” from the angles and describe learning, adjusting and preparing.

The history of the houses

Hellenistic astrologers, writing in Greek from about the second century BC, called the houses topoi, “places”, and counted twelve of them from the rising sign. The places had traditional names, and seven of them were assigned a classical planet that rejoiced there: Mercury in the first, the Moon in the third (“the Goddess”), Venus in the fifth (“Good Fortune”), Mars in the sixth (“Bad Fortune”), the Sun in the ninth (“the God”), Jupiter in the eleventh (“Good Spirit”) and Saturn in the twelfth (“Bad Spirit”). These joys still explain much of each house’s tone.

Medieval Latin astrology renamed the places domus, “houses”, and students memorised them in a single verse: vita, lucrum, fratres, genitor, nati, valetudo, uxor, mors, pietas, regnum, benefactaque, carcer: life, gain, brothers, father, children, health, spouse, death, piety, kingdom, benefactors and prison.

The question of where each house begins produced the house systems. The earliest texts used whole-sign houses, where the rising sign is the whole first house. Quadrant systems divide the space between the angles instead: Porphyry in late antiquity, Regiomontanus in the fifteenth century and Placidus, named after the seventeenth-century monk Placidus de Titis, who helped popularise it; printed tables of houses later made it a widely used system. Twentieth-century psychological astrology then read each house as a field of experience rather than a list of events.

Where to begin with the twelve houses

Start at the angles. Locate the ascendant, IC, descendant and Midheaven. In Placidus they form the cusps of the first, fourth, seventh and tenth houses; other systems place the angles within houses. A planet close to an angle adds emphasis to its theme, whatever house it occupies.

Count where the planets gather. Most planets above the horizon (houses 7 to 12) point to a life lived outward, among others; most below it (houses 1 to 6), to a life built from the inside. Most in the east (houses 10 to 3) favour self-direction; most in the west (houses 4 to 9), meeting others halfway. A house holding three or more planets becomes a theme of the chart.

Read the cusp sign, then its ruler. The sign on a house cusp gives the style of that area. The planet ruling that sign shows where the area connects: with Scorpio on the second-house cusp, look at Mars, and at Pluto if you use modern rulers.

Pair each house with its opposite. The houses work in six axes: self and partner (1–7), mine and ours (2–8), near and far (3–9), roots and reputation (4–10), personal joy and the group (5–11), daily duty and quiet retreat (6–12).

Don’t read a house as an event. A planet in a house describes an area that matters, not something fixed to happen there. Saturn in the seventh describes taking partnership seriously, not a delayed or unhappy marriage.

The Larisa app’s Birth Chart lays out all twelve houses in the Placidus system from your birth date, time and place. With no known time the app sets the chart for about 12:00 noon to give you a result; the cusps can then be off by several signs, so treat the houses as a sketch until the time is confirmed.

One chart at a time: houses in action

A crowded tenth house. The Sun, Mercury and Saturn all in the tenth: career and reputation sit at the centre of the story. The person may feel judged by results and measure each year by what they built. The opposite fourth house, empty here, is read through its ruler, and that is where the question of rest and belonging lives.

Venus in the third house versus the eleventh. Two people with the same Venus sign. With Venus in the third, affection runs through conversation, letters and siblings; love begins with a good talk. With Venus in the eleventh, it runs through friendship and shared causes; many partners begin as friends.

Planets mostly below the horizon. Seven of ten planets in houses 1 to 6. The emphasis falls on private experience: study, home life, craft and daily routine. Read it as a question about where the person puts their attention and effort, rather than a timetable for entering public life or a fixed description of shyness.

An empty seventh house. No planets in the seventh does not mean no partner. With Gemini on the cusp and Mercury in the ninth, partnership is lived through ideas, travel and a partner who widens the person’s world.
