What is First house in Western astrology?

Definition

First house is the first of the twelve houses in a Western astrological chart, tied to the Ascendant, the sign rising on the eastern horizon at birth, and to the person's life, stature, complexion, and form in William Lilly's Christian Astrology.

In plain words

The First House is the first of the twelve houses in a Western astrological chart and is usually linked to the Ascendant, the sign rising on the eastern horizon at birth. William Lilly, in Christian Astrology, tied this house to the life of a person and to their stature, complexion, and form. The Wikipedia article on House (astrology) extends the reading to self-identity, physical appearance, and the persona, meaning the outward expression of one's inner world.

History

The First House appears in the classical astrological tradition through William Lilly, whose Christian Astrology lists what the house signifies. Lilly states that the first house signifies the life of man, along with the stature, colour, complexion, form and shape of the person who propounds the question or is born. In his account the house is the starting point for reading a person's bodily life and outward make-up, so it anchors the chart's reading of the self. Lilly also ties Mercury to this house because Mercury represents the head, the tongue, fancy and memory. He adds that a well-dignified Mercury posited there produces good orators.⁶

Topics, strength and planetary joy

First house, house 1, is associated with life, body, appearance. Topic lists describe a symbolic tradition, so the house is read as a set of themes rather than a fixed rule. Lilly's list is the older anchor for these associations.⁶

First house is angular, meaning it sits at one of the four chart angles. Angular, succedent and cadent identify a house's relation to those four angles, which helps a reader place it within the wider chart structure.⁶

Mercury has its traditional joy in this house. Lilly ties this to the head, the tongue, fancy and memory, so a reader can see why Mercury features in first-house interpretation.⁶

The rising sign is the whole first house in whole sign systems. Quadrant systems begin the first house at the Ascendant degree, so the boundary of the house can shift between methods.⁶

The astronomy

Skyscript's House Ruler entry gives a worked example from the nativity of Orson Welles, where the first house cusp falls in the 25th degree of Gemini. Because Mercury is the planetary sign-ruler of Gemini, Mercury becomes the principal ruler of the first house in that chart.⁵

The Wikipedia article on House (astrology) explains that in whole sign houses the first house cusp is the beginning of the sign containing the ascendant. In equal houses the degree of the ascendant is itself the first house cusp, so the same rising point gives two different cusp positions depending on the system.³

Where astrologers differ

The Wikipedia House (astrology) article explains that in whole sign houses the first house cusp is the beginning of the sign containing the ascendant, while in equal houses the ascendant degree itself is the first house cusp. It also notes that quadrant systems place the ascendant on the first house cusp and the midheaven on the tenth, and that the Placidus and Koch systems can generate undefined results in the polar circles. Skyscript's House Ruler entry illustrates the ruler question with Orson Welles's nativity, where the first house cusp falls in the 25th degree of Gemini, making Mercury the principal ruler of the first house.

Worked out from the evidence

Reasoned from the cited facts, not stated outright by any one source.

Because Lilly's account of the first house ties it to the body and the Wikipedia account ties it to the persona, a reader can treat the house as the point where the chart's bodily reading and its outward self-presentation meet.

Because the Wikipedia angular-houses entry says the Ascendant is often but not always the first house cusp, and the House (astrology) article says whole sign and equal systems place the cusp differently, the first house's exact starting degree depends on the house system chosen.

Not yet confirmed

• Whether the first house should always be read as the Ascendant sign when a chart uses a house system that places the cusp elsewhere is a question the cited sources leave open.
• How the first house's themes of body and persona should be weighed against a Sun sign that the Ascendant overshadows is not settled by the cited sources.
