What his chart says about him

  1. Who he was

    Sun in Cancer, the Protector

    Tender under a careful shell. Makes a home anywhere and guards the people inside it. He fought hard for what he wanted, and his temper was part of his courage.

    The Sun opposition Mars (close at 1.4°)

  2. What he needed

    Moon in Gemini, the Talker

    Sorts out feelings by putting them into words. Needs company, news and a change of scene.

  3. How he loved

    Venus in Gemini, the Charmer

    Loves with words and wit. Needs a partner to talk with late into the night. Love felt like something to be earned, and he held back until he was sure of it.

    Venus square Saturn (close at 1.8°)

  4. How he thought

    Mercury in Leo, the Storyteller

    Speaks with warmth and confidence and tells a great story. Thinks in big, bold ideas.

  5. What drove him

    Mars in Capricorn, the Achiever

    Determined, controlled and built for the long climb. Works patiently toward the top. Drive and dreams mixed uneasily: the goal was clear to him, and the way to it harder to see.

    Mars opposition Neptune (almost exact at 0.6°)

  6. The shape of his chart

    In his chart, his identity, his optimism and his imagination (the Sun, Jupiter and Neptune) gather in Cancer, and that part of life drew his attention first. Most of his planets are in water signs: feeling and intuition.
