Fragment of a relief sculture showing one of the Dioscuri (Castor/Pollux). They are called the Dioscuri (dios kouroi) which means the 'Sons of Zeus', although the story of their parentage is confused, as it is for their sisters Helen and Clytemnestra. The Gemini or Gemini twins, known in Roman mythology as Castor and Pollux and in Greek as Kastor and Polydeuces, are the twin sons of Leda and the brothers of Helen of Troy and Clytemnestra.
