Legendary horseman in the Roman Empire.

So here we have the Roman Empire Didrahma (Kvadrigat). The year of issue of this coin is 225 – 215 century BC.

Dioscuri, in Greek and Roman mythology, twin deities who succoured shipwrecked sailors and received sacrifices for favourable winds. They were the children of Leda and either Zeus, the king of the gods, or Tyndareus, Leda’s mortal husband and the king of Lacedaemon. According to the usual version, Castor was the son of Tyndareus and thus was mortal, while Pollux was the son of Zeus.

Both brothers were fine horsemen, and Pollux was an unrivaled boxer. They took part in the hunting of the Calydonian boar and in the voyage of the Argo. When their sister Helen was abducted by Theseus, they invaded Attica and recovered her. They carried off the daughters of Leucippus, Phoebe and Hileira, and were confronted by Leucippus’s nephews, Idas and Lynceus.

Castor was murdered by Idas, but Pollux killed Lynceus; in retribution Zeus killed Idas with a thunderbolt. Zeus then gave Pollux 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. Pollux elected to share his immortality. In one version of the story, they became the constellation Gemini.
