Definition

Derived houses are an astrological technique that consists of counting from a natal house to obtain information about loved ones, the finances of others, or events involving a third party in the chart.

Want to understand how derived houses in astrology work? Many astrologers overlook this technique, yet it is essential for reading the events affecting those around you in a natal chart. This complete guide teaches you the counting rule, the fundamental derivations and the full family mapping.

How derived houses reveal a cosmic hologram

Imagine that your natal chart is not merely a map of your own psyche, but a cosmic hologram containing the lives of everyone around you. That is exactly the promise of the astrological technique of derived houses.

Stemming from the Hellenistic tradition and popularised by horary and medieval astrology, this method makes it possible to turn any astrological house into a new Ascendant (House I). The wheel of the zodiac thus pivots to reveal your partner's finances, your mother's career, or even your uncle's secrets.

Though formidably powerful, this technique demands mathematical rigour and great clarity of mind. Let us dive into this celestial mechanism to master all its branches.

Axiom and Definition

Derived houses rest on a fundamental axiom: each astrological House in your natal chart can be regarded as House I of another person.

To use this technique, you count from the 'Pivot' house (the one representing the person studied), always including it as House 1 of that person.

For example, if you want to know your spouse's finances, you take House VII (the spouse) as the starting point. Their finances correspond to their House II. So you count two houses from House VII (VII counts as 1, VIII counts as 2). Your spouse's finances are therefore read in your natal House VIII.

The Golden Rule of Counting

The main mistake astrology students make lies in the calculation. In astrology, counting is always inclusive. There is no 'zero'.

1

The Main Pivot

Identify the house that represents the person concerned. E.g. House III for a brother, House X for the mother, House VI for an employee.

2

The Subject of the Question

What are you trying to learn about this person? Their health (VI), their money (II), their children (V) or their secrets (XII)?

3

Inclusive Counting

Start counting on the zodiac wheel. The Pivot house is ALWAYS house number 1. Turn counter-clockwise.

4

The Derived House

The point of arrival is the Derived House. Analyse its sign, its planetary ruler and the planets it contains in your chart.

The Encyclopaedia of Derivations

Here is a list of the derivations most validated by centuries of astrological practice.

VIII
House II of the VII

The Partner's Finances

House VIII represents your spouse's money. If Jupiter is there, your partner could be financially comfortable. If Saturn is there, they could go through financial crises that will affect your relationship.

XI
House II of the X

The Fruits of the Career

House XI (projects) is also House II of the X. It describes very concretely the money generated by your profession or the bonuses received from your superiors.

XII
House VI of the VII

The Spouse's Health

Your twelfth house (hidden trials) is the sixth house (illness) of your partner. Heavy planetary transits in your XII often coincide with the illness of your beloved.

IV
House X of the VII

The Spouse's Reputation

Your home (House IV) represents your spouse's standing in the world (House X). Your intimate balance often depends on their outer success.

The Great Family Mapping

The natal chart is a coded family tree. Here is how to locate any member, from the ex-wife to the nephew, with mathematical precision.

Ancestry & Uncles

The MotherHouse X

Authority (modern tradition) or House IV (Hellenistic tradition).

The FatherHouse IV

Roots (modern tradition) or House X (Hellenistic tradition).

Maternal Uncles & AuntsHouse XII

The mother's siblings. (House III counted from the X = House XII).

Paternal Uncles & AuntsHouse VI

The father's siblings. (House III counted from the IV = House VI).

Siblings & Descendants

The 1st ChildHouse V

The first child conceived or the first pregnancy.

The 2nd ChildHouse VII

Masterclass: 5 Practical Case Studies

Case Study #1

Case #1: The Ex-Husband's Bankruptcy

Question asked

Will my ex-husband, with whom I am in a financial dispute, go bankrupt?

Celestial Data

House VII in Aries. House VIII (2 of 7) in Taurus, occupied by Uranus afflicted by Saturn.

Astrological Analysis

“ The ex-husband (1st spouse) stays in VII. His finances are read in House VIII (House II derived from the VII). Uranus severely afflicted by Saturn in this house indicates a drastic and sudden restriction of his assets, confirming a bankruptcy that could block your alimony. ”

Case Study #2

Case #2: The Second Child's Success

Question asked

Will my second child finally find their professional path?

Celestial Data

House VII (2nd child) in Sagittarius. Natal House IV (10 of 7) in Pisces with Jupiter at the Midheaven.

Astrological Analysis

“ The second child is signified by House VII. Their career is their own House X (10 of 7), which brings us to your natal House IV. A very strong Jupiter (success, expansion) indicates that this second child will enjoy a spectacular professional rise. ”

Case Study #3

Case #3: The Brother-in-law's Secret

Question asked

Is my husband's brother (my brother-in-law) hiding serious things from us?

Celestial Data

House IX (brother-in-law) in Virgo. Natal House VIII (12 of 9) housing Neptune badly aspected.

Astrological Analysis

“ The brother-in-law (House III from the VII = House IX). His secrets are read in his own House XII (12 of 9), which corresponds to your natal House VIII. Neptune (lies, concealment) is very badly aspected there. The verdict is final: he is hiding a reality (often financial or debt-related given the nature of the 8th house). ”

Case Study #4

Case #4: The Nephew's Inheritance

Question asked

Will my nephew grow rich through his father's estate?

Celestial Data

House VII (the nephew) in Libra. Natal House II (8 of 7) in Taurus with Venus and Pluto conjunct.

Astrological Analysis

“ The nephew (child of the sibling: 5 of 3) is found in House VII. His inheritance is read in his House VIII. Counting 8 houses from the VII, we land on your natal House II. The Venus/Pluto conjunction (extreme wealth) confirms a massive influx of capital for this nephew. ”

Case Study #5

Case #5: The Maternal Aunt's Health

Question asked

Will my aunt on my mother's side recover from her operation?

Celestial Data

House XII (maternal aunt) in Scorpio. Natal House V (6 of 12) with Mars in fall in Cancer.

Astrological Analysis

“ The maternal aunt (the mother's sister: 3 of 10) is House XII. Her health is read in her House VI (6 of 12), namely your natal House V. Mars (surgery, inflammation) in fall indicates that the operation will be complicated and that recovery will require a great deal of time and energy. ”

Warnings and Ethics

Dilution of the symbol: In theory, one could look for 'my uncle's ex-wife's dog'. In practice, beyond two derivations the astrological meaning becomes blurred. Stay focused on direct links.

The ethical question: Prying into your ex-wife's finances or your brother-in-law's secrets without their consent is voyeurism. Astrology demands nobility of soul.

The Natal Chart Always Prevails: A derived house shows YOUR perception of a person through your own chart. It will never replace that person's actual natal chart.

The Integral Matrix

“ Derived houses turn astrology into a breathtaking holographic language. A simple wheel of 12 sectors is enough to tell the story of an entire family. ”

“ To understand this technique is to touch a fundamental spiritual reality: nothing is separate. Your maternal aunt's health and your ex-husband's money are part of the same great celestial algorithm. ”

Frequently Asked Questions (FAQ)

If I have three brothers, how can House III describe them all?

House III describes siblings in general. To individualise, tradition assigns the III to the eldest, then you jump in twos (House V for the second, House VII for the third).

Are the lunar nodes taken into account in derived houses?

Yes. A South Node in the derived house of your ex-spouse's finances may indicate that they are undergoing an inevitable karmic or material loss.

Should you use Placidus or Whole Signs?

Derived houses work better with the Whole Signs system, because the technique was conceived in the Hellenistic era when 1 House = 1 Sign.

Can derived houses be used in synastry?

Yes, derived houses considerably enrich the analysis in synastry. For example, House VIII (derived from the VII) represents the partner's finances, and House IX (3rd derived from the VII) their siblings. This technique lets you read, within your own chart, information about your spouse's loved ones.
