What her chart says about her
Who she was
Sun in Sagittarius, the Explorer
Restless in the best way. Wants to see more, learn more and say exactly what is on her mind. She took in moods, music and other people’s hopes, and gave them back as something new.
The Sun conjunction Neptune (close at 1.9°)
What she needed
Moon in Aries or Pisces, the Quick Flame
Quick to feel and quick to forgive. Needs to say it, do something about it and move on. Her feelings liked freedom: she needed space in close ties and gave it back just as easily.
The Moon trine Uranus (close at 2.6°) · For a birth before 1:46 a.m., her Moon was in Pisces.
How she loved
Venus in Scorpio, the Devotee
Loves fiercely, privately and for keeps. Wants complete trust and a bond that goes beneath the surface. A generous heart: love and good company came to her easily, and she shared both.
Venus conjunction Jupiter (almost exact at 0.7°)
How she thought
Mercury in Sagittarius or Scorpio, the Philosopher
A wide-ranging mind. Learns by asking, travelling and following a question as far as it goes.
For a birth before 4:06 a.m., her Mercury was in Scorpio.
What drove her
Mars in Aries, the Trailblazer
All drive, courage and quick starts. Goes first, acts fast, and is at her best when something needs doing now. She worked for ideals: her drive came alive for a cause, a role or a dream.
Mars trine Neptune (almost exact at 0.8°)
