We should have a little respect for astrology. Our forebears first accurately mapped the stars and planets for astrological reasons. Astrology is the baby that grew up to become astronomy. Humans believed in astrology because the sun, moon and planets move regularly through part of the starry sky called the Zodiac. The planets were gods in those days, and the gods certainly influenced people's lives.

The star farthest to the north and most nearly overhead is the right claw of the crab. I think you know what end we're talking about here. Remember, if your birth sign is Cancer, you must be, well, crabby. Cancer, I am sorry to report, was not a pleasant figure, if the old stories about it are to be believed. The Crab is one of several constellations that are connected with the twelve labors of Hercules.
