🏛️ Mythology – The Crab and Hercules:
In Greek mythology, Cancer represents the giant crab sent by Hera, queen of the gods, to distract Heracles (Hercules) during his battle with the multi-headed serpent Hydra.
The crab tried to attack Hercules, but he crushed it underfoot.
As a reward for its efforts, Hera placed the crab among the stars, though in a less prominent position to reflect its defeat.
This is why Cancer is faint compared to other zodiac constellations.
🧭 How to Find Cancer:
