In the Ancient Greek myth, Cancer was a crab sent by Hera to attack the feet of Heracles in an attempt to thwart him as he fought the Hydra. Heracles stomped on and crushed the crab then slew the Hydra. Hera, in gratitude for the creature’s efforts, honoured the crab by placing it in the stars. Sterling silver pendant on a 20 inch (50 cm).
