🜂 House Description

The 1st House represents personal identity and how one meets the world. It governs how you initiate action, present yourself, and the instinctual way you approach life. Planets here have a powerful influence on your outward personality, vitality, and physical body. The Ascendant (Rising Sign) is located here, making this house central to the way others perceive you — and how you come to know yourself.

Cusp arithmetic. In whole-sign houses the 1st house is the entire 1st sign counted from the rising sign: sign(H1) = (sign(ASC) + 0) mod 12. In equal houses its cusp is ASC + 0°. In quadrant systems (Placidus, Koch, Porphyry, Regiomontanus, Campanus) the cusp is computed from RAMC, obliquity and latitude — see House Systems.

Hellenistic names, joys and Lilly’s significations are optional correspondences beneath the vault’s own house definition above.
