What his chart says about him

  1. Who he was

    Sun in Leo, the Bright One

    Warm, generous and made to be seen. Makes a room feel brighter and wants the people in it to shine too. More sensitive to criticism than it looks. He reached for more than one life could hold: big plans, big promises, and a habit of saying yes before counting the hours.

    The Sun opposition Jupiter (wide at 9.0°)

  2. What he needed

    Moon in Taurus, the Hearth

    Settled by simple, solid comforts: a good meal, a quiet evening, the same people year after year.

  3. How he loved

    Venus in Cancer, the Nurturer

    Loves by caring and protecting. Wants a partner who feels like home. Romance without limits: he fell for ideals as much as people, and his taste ran to the dreamy and the beautiful.

    Venus conjunction Neptune (almost exact at 0.8°)

  4. How he thought

    Mercury in Cancer, the Remembering Mind

    A mind tuned to people. Hears what sits under the words and answers it gently. Ordinary logic and sudden insight needed constant translating, and he spent time explaining how he got there.

  5. What drove him

    Mars in Cancer, the Defender

    Driven by feeling. Goes the furthest for something personal, and guards home fiercely. Magnetic: affection and desire came together in him, and people noticed.

    Venus conjunction Mars (close at 2.0°)

  6. The shape of his chart

    In his chart, his mind, his heart, his drive and his imagination (Mercury, Venus, Mars and Neptune) gather in Cancer, and that part of life drew his attention first. The weight of his chart sits in water signs: feeling and intuition.
