Castor and Pollux Castor and Pollux Castor and Pollux (or in Greek, Polydeuces) were twin half-brothers in Greek and Roman mythology, known together as the Dioscuri. Their mother was Leda, but they had different fathers; Castor was the mortal son of Tyndareus, the king of Sparta, while Pollux was the divine son of Zeus, who seduced Leda in the guise of a swan. Though accounts of their birth are varied, they are sometimes said to have been born from an egg, along with their twin sisters Helen of Troy and Clytemnestra. In Latin the twins are also known as the Gemini (literally "twins")
Castor et Pollux Castor et Pollux Castor et Pollux ("Castor and Pollux") is an opera by Jean-Philippe Rameau, first performed on 24 October 1737 by the Académie royale de musique at its theatre in the Palais-Royal in Paris. The librettist was Pierre-Joseph-Justin Bernard, whose reputation as a salon poet it made. This was the third opera by Rameau and his second in the form of the "tragédie en musique" (if the lost "Samson" is discounted). Rameau made substantial cuts, alterations and added new material to the opera for its revival in 1754. Experts still dispute which of the two versions is superior. Whatever
