The Offering of the Dioskouri.

The divine twins, Kastor and Polydeuces (Castor and Pollux to the Romans) were the brothers of Helen of Troy and Clytemnestra.

Despite one being mortal and one being immortal, they were devoted to one another. When Kastor was killed, Zeus gave Polydeuces the choice between spending all his time on Olympus or giving half of his immortality to his mortal brother, so that they could alternate realms together. Polydeuces elected to share his immortality.

My rendering of "Castor and Pollux" is inspired by the marble statue of them in the sculpture court of the V&A museum, London.
"This marble group is a close copy of a heavily restored antique group originally excavated in Rome (it was recorded in the Ludovisi Collection in 1623), and later in the collection of Queen Christina of Sweden in Rome. The antique group was sold to Philip V of Spain in 1724, and is now in the Prado, Madrid. Joseph Nollekens (1737-1823) probably made his marble version from the plaster copy kept at the French Academy in Rome." (text courtesy V&A)

The arcadian landscape in which the brothers stand, is inspired by a landscape by Nicolas Poussin of St John on Patmos.
