History

William Lilly's Christian Astrology, published in 1647, presents the Seventh House as the house of marriage, and Lilly calls it the Angle of the West. Lilly's text gives judgement of marriage and describes the person inquired after, so the sector is read mainly through partnership questions. Later modern writers keep the link to partnership but reframe it around balance and negotiation. Each source names its own emphasis, so a first-time reader can compare them directly rather than treat any single list as settled. Seen this way, the seventh house is a sector whose meaning depends on the tradition that reads it, and that difference is useful to notice before judging any single account.⁵

Topics, strength and planetary joy

Number and topics

Seventh house, house 7, is associated with partners, contracts, and open opponents. Topic lists describe a symbolic tradition rather than a measured fact, so each topic is a convention to be studied. The sector is taken as a field for learning about cooperation and conflict.⁵

Cadency

Seventh house is angular; angular, succedent and cadent identify relation to the four chart angles. The seventh house shows the type of mate a native is likely to be attracted to and all partnerships in general, and it is one of the four angular houses where the chart's angles are found.⁵³

Planetary joy

The seventh house has no planet in its traditional joy. This statement describes the traditional rule set, and it helps a reader separate a symbolic rule from a measured quantity.⁵

House-system distinction

The sign opposite the rising sign is the whole seventh house in whole-sign systems, while quadrant systems begin it at the Descendant degree. Naming this choice keeps the convention visible for a first-time reader.⁵

Where astrologers differ

Rudhyar sees the Seventh House as the point where personal identity meets the Other, symbolizing the evolution of self through meaningful connections. Lilly, in Christian Astrology of 1647, treats the same sector mainly as the house of marriage and judgement, calling it the Angle of the West. Arroyo emphasizes committed partnership, harmony, and negotiation. Wikipedia's article on house (astrology) summarizes modern usage as the House of Balance. A reader can compare these accounts side by side: each names a different emphasis, and each is an interpretive tradition rather than a measured astronomical fact.

Worked out from the evidence

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

Because Lilly calls the Seventh House the Angle of the West and also says it is one of the four angular houses, a reader can treat its partnership meaning as tied to the chart's angles, a link no single source states.

Lilly's marriage judgement and the modern House of Balance reading both place partnership at the center of this sector, so the two traditions share a core theme even though they differ in emphasis.
