Greek & Roman Mythology
- the twins Castor and Pollux, born to Leda after her seduction by Zeus. Castor was mortal, but Pollux was immortal; at Pollux’s request they shared his immortality between them, spending half their time below the earth in Hades and the other half on Olympus. They are often identified with the constellation Gemini.
from Greek Dioskouroi 'sons of Zeus'
