A temple to Castor and Pollux is seen within the forum at Rome.  Tempio dei Dioscuri   It is marked by three remaining columns supporting a friezework. Other sites mark these roman champions,  like the one pictured above near government house in Rome.  The temple was constructed in 117BC by Lucius Caecilius Metellus Damacticus after his victoryover the Dalmation peninsula. The temple was considered the secret planning place of  the senate (E Gibbon Delcine and fall of the roman empire vol 1 pg 323) amd used to plot the action against Emperor Maximian (Marcus Aurelius) in April 307. This was the military expert that ruled in conjunction with Diocletian, (the thinking party of the union!)

Castor and Pollux were the mythical champions of the battle of Lake Regilius 495BC appearing as charging horseman, the twins of Zeus. They became known as the horsetrainers, and teh guardians of the mariners. They are the sons of Leda and the brothers of Helen of Troy and Clytemnestra. According to Liddell and Scott’s Lexicon, kastor is Greek for “he who excels”, and poludeukeis means “very sweet”.

Paul was to set ship on a ship of Alexandria which sailed under the sign of Castor and Pollux Acts 28:11

The twin gods became features of numerous other locations or geographical features such as the twin peaks of Zermatt, Valais, Switzerland, monuments in the gardens of the Chateau deVersailles, and in mosaics of Paphos Cyrus.
