or Castor and Pollux
(from Greek dioskouroi , "sons of Zeus") Twin gods of ancient Greece and Rome.
They aided shipwrecked sailors and accepted sacrifices for favorable winds. Castor was mortal and Pollux was immortal; when Castor was killed, Pollux disowned his immortality to join his brother. Zeus later changed them into the constellation Gemini . They were believed to have aided the Romans in an important battle early in their history, and a temple in their honour was built in the Roman Forum.
