Gemini
The mortal Castor and immortal Pollux, the Heavenly Twins of Gemini, stood for Life and Death in ancient Rome and are a symbol of the coexistence of the mortal and immortal parts of man. They also calmed rough seas for sailors; twin balls of lightning in the rigging, now known as St. Elmo's fire, were a guarantee of safety from the storm. They are also said to have led the Roman cavalry to victory in a great historic battle. That evening, they appeared, both dressed in purple, watering their white horses at the fountain in Rome's forum. The two bright stars, Castor and Pollux, which have also been seen as twins in Asia, Australia and Polynesia, lie next to Taurus on the zodiac band, above the Great Hunter, Orion.
