Confusions about derived houses Part 1

There is a lot of confusion about how to identify the planet representing someone or something belonging to a series. Examples include:

  • The 2nd husband,
  • 3rd property on offer for purchase,
  • 2nd in a choice between 2 schools, and
  • the 3rd sibling.

One theory concerns derived houses. However in order to explain derived houses it is necessary to understand the astrological convention for counting the houses.

Counting the houses

We count the house we are starting with as house number 1 and count in an anti-clockwise direction.
Derived HousesExample 1
Identifying which house represents the sister-in-law. The 3rd house represents siblings. The 7th represents the spouse. Therefore the 3rd house from the 7th house represents the spouse’s sister (sister-in-law).
Count 1 for the 7th house, count 2 for the 8th house, and 3 for the 9th house. The 9th represents the sister-in-law.
Example 2

A client asks “Where is my child’s bicycle?”. Their child is the 5th house, and the bicycle is the 2nd from the 5th. Count 1 for the 5th house and 2 for the 6th house. This is the radical 6th house. The ruler of the 6th house represents the child’s bicycle.

Derived houses

These are alternatively called ‘turned’ or ‘rotated’ houses, are used in both horary and natal astrology. A derived house has a special relationship to something or someone in the client’s life. The use of derived houses enables us to identify the planetary significator of almost anything or anyone.

Generally the meanings of the houses are considered relative to the 1st house, which represents the client. The principle of derived houses takes these meanings and applies them to the house representing whatever is asked about. The house which represents the person or thing asked about is counted as number 1 and the meaning of all the other houses are considered relative to this house.

Siblings – The classic case

The concept of the 3rd from the 3rd is based on the idea of siblings where sibling 1 is Lord 3, sibling 2 is the 3rd from the 3rd house = the 5th house, sibling 3 is the 3rd from the 5th house = the 7th house; and so on. This makes sense because each sibling is a sibling of the other.

However some astrologers have made the mistake of extrapolating to people or things belonging to a series where successive person or thing is unrelated to the previous person or thing.
For example if you went to 2 primary schools the 1st would be represented by the ruler of the 3rd house but the second would not be represented by the 3rd from the 3rd house. The 2nd school is not the school of the previous school. It doesn’t make sense.

Neither can we extrapolate this principle to children. Your second child is not represented by the 5th house from the 5th house. It does not make sense that the 2nd child is the child of the 1st child. Unless of course you partnered with your first child to have another child, which is exceptionally rare and considered morally reprehensible in modern society.

Neither can we apply the this principle of derived houses in a related series to determine which planet represents a specific spouse. Example questions include:

  • Which house represents my 2nd wife?
  • Which house represents my 3rd husband?

In the first example the 2nd wife cannot be represented by the 7th house from the 7th house because she is not the wife of the first wife. She is not related to the 1st wife as a wife. In does not make sense and does not reflect reality.

I will cover how to identify the ruler of people or things in an unrelated series in a future post.
