Story Behind Gemini Constalletion: Gemini is the sign of the twins is represented by the ancient Greek brothers Castor and Pollux. Born to Leda of Sparta, Pollux, a powerful boxer, was the immortal son of Zeus while his twin brother, Castor, a great horseman, was the mortal son of a Spartan King. Castor and Pollux had many adventures together, until one day when Castor was mortally wounded in battle. Pollux was sad and did not wish to go on without his loving brother. But because he was immortal, Pollux had little choice. He went to his father Zeus and asked to share his immortality with his brother. Although Zeus was the king of the gods, even he had limitations. But because he loved his son Pollux so much, Zeus arranged a deal with his brother Hades. Hades agreed to release Castor for part of the year, provided Pollux would take his place in the underworld during that time. So each brother spends half of his time in the Underworld and half on Olympus forever. Even though they could not be together, Pollux was consoled by the fact that his brother, like he, would be immortal. Eventually, as sign of their deep commitment to each other, Castor & Pollux were placed in the sky as the constellation Gemini, where they will be together for eternity.
