The mythology of the constellation of Cancer
The mythology of the constellation of Cancer, also known as the “Crab,” can be traced back to ancient Greek and Roman times.
In Greek mythology, Cancer is associated with the story of Hercules and the Hydra. According to legend, the Hydra was a multi-headed serpent that terrorised the countryside. Hercules was tasked with killing the Hydra, but every time he cut off one of its heads, two more grew back in its place. As Hercules fought the Hydra, the goddess Hera, who was a sworn enemy of Hercules, sent a giant crab to attack him.
The crab, known as Karkinos, latched onto Hercules’ foot with its powerful claws, hoping to distract him from the fight with the Hydra. But Hercules crushed the crab with his foot, killing it instantly. In recognition of the crab’s bravery, Hera placed the crab in the sky as a constellation.
In Roman mythology, the Cancer constellation is associated with the goddess Juno, who was the wife of Jupiter. Juno was often depicted holding a crab, which was said to represent the constellation. In some versions of the myth, the crab was sent by Juno to distract Hercules during his battle with the Hydra, rather than by Hera.
In Egyptian mythology, the Cancer constellation was associated with the scarab beetle, which was believed to symbolise resurrection and immortality. The scarab beetle was thought to roll the sun across the sky, just as the Cancer constellation was thought to mark the path of the sun during the summer solstice.
In Chinese mythology, the Cancer constellation is part of the larger constellation known as the “Black Turtle,” which is associated with the north and the element of water. The Black Turtle is one of the four symbols of the Chinese constellations and is often depicted as a turtle with a snake coiled around its back.
In Celtic mythology, the Cancer constellation was associated with the goddess Cerridwen, who was known as the keeper of the cauldron of knowledge. According to legend, Cerridwen used the cauldron to brew a magical potion that could grant wisdom and enlightenment. The Cancer constellation was said to represent the cauldron and the stars within it, the sparks of wisdom that emanated from it.
Throughout history, the Cancer constellation has been associated with a variety of myths and legends. Today, it is recognized as one of the twelve zodiac signs and is associated with the element of water, the moon, and the qualities of nurturing, empathy, and intuition.
