Cancer is 1 of 12 Zodiacs. Cancer is Latin for Crab. Cancer was Introduced in The 100's AD by The Roman Astronomer Ptolemy who named it Karkinos which is Almagest (100 AD Greek Astronomical and Mathematical Language) for Giant Crab. In The Classical World Tradition, Cancer is the crab which pinched Hercules's foot while Hercules (Heracles) was in battle with The Hydra during his 12 labors. Hercules killed Cancer after the foot bite. Hera, who hated Hercules, placed the Crab in the night sky in honor of it attacking her enemy Heracles.
