Cancer

general summary for a strong Cancer placement

What the tradition reads

Cancer is the cardinal sign of water, the sign that opens the season of summer and begins the zodiac's second, maternal trio. Its ruling planet is the Moon, and the tradition reads Cancer as the sign of retention: memory, feeling and attachment held onto long after the moment that produced them has passed. Alan Leo's Astrology For All singles out the sign's remarkable memory as its defining trait, describing Cancer natives as tenacious as the crab that gives the sign its symbol, willing to lose a claw before releasing what it has taken hold of, and notes a corresponding sensitivity to family and home that can become, Leo writes, a kind of brake on a person's own progress when it goes unchecked. The tradition credits Cancer with imagination, loyalty and a protective instinct toward whatever it considers its own, alongside a private, sometimes guarded nature that fears ridicule more than most signs admit to fearing anything. Cancer governs the fourth house in the natural wheel, the house of home, family and emotional roots, and the sign is read as the zodiac's instinct for shelter, the place a person returns to rather than the place a person performs in. Its shadow is a moodiness that clings to old hurt; its gift, matured, is a devotion that does not waver once it is given.

The story

Cancer's crab enters Greek myth in the story of Heracles's second labour, his fight against the many headed Hydra in the marsh of Lerna. As Heracles struggled with the monster, the goddess Hera, who bore him no goodwill, sent a crab, the Karkinos, to distract him by pinching at his feet; Heracles crushed it underfoot without much difficulty, but Hera, in gratitude for its small service against her enemy, placed its remains among the stars as the constellation Cancer. In the Roman retelling it is Juno, Hera's counterpart, who performs the same act for the same reason. The crab's part in the larger story is brief and, on its own terms, a failure: it accomplishes nothing against Heracles and dies for the attempt, yet is rewarded with a permanent place in the sky regardless. Older civilisations read the same patch of stars differently before the Greeks fixed the crab there: the Egyptians saw a scarab beetle in it, and Mesopotamian astronomers a turtle, each culture reaching for its own small, hard shelled creature to mark the same point in the year. The tradition finds something apt in a sign named for a creature that endures by retreat and protection rather than by victory.
