Temple of Castor and Pollux Temple of Castor and Pollux The Temple of Castor and Pollux () is an ancient temple in the Roman Forum, Rome, central Italy. It was originally built in gratitude for victory at the Battle of Lake Regillus (495 BC). Castor and Pollux (Greek Polydeuces) were the Dioscuri, the "twins" of Gemini, the twin sons of Zeus (Jupiter) and Leda. Their cult came to Rome from Greece via Magna Graecia and the Greek culture of Southern Italy. The Roman temple is one of a number of known Dioscuri temples remaining from antiquity. The last king of Rome, Lucius Tarquinius Superbus, and
Leda and the Swan were derivative of the compositions mentioned above. The subject remained largely confined to Italy, and sometimes France – Northern versions are rare. After something of a hiatus in the 18th and early 19th centuries (apart from a very sensuous Boucher,), Leda and the Swan became again a popular motif in the later 19th and 20th centuries, with many Symbolist and Expressionist treatments. Also from that era were sculptures of the theme by Antonin Mercié and Max Klinger. Cy Twombly executed an abstract version of "Leda and the Swan" in 1962. It was purchased by Larry Gagosian for $52.9 million at
