Description:This denarius coin was minted in Rome by moneyer L. Procilius in 80 BC. In ancient Roman religion, Jupiter was the king of the gods and the god of sky and thunder. He was the equivalent of Zeus to the Greeks. With his wife Juno, he ruled over laws and social order. Juno is depicted on the reverse of this coin holding a shield and spear with a serpent by her feet. Juno could also throw lightning bolts like Jupiter. Her Greek equivalent is Hera and she was called Regina "queen". As “the protector” she guarded over the finances of the empire and had a temple in Rome which was also the mint. Juno was the patroness of marriage and many people believe that the most favorable time to marry is June, named after her.
Beginning in 509 BC, the largest temple in Rome was that of Jupiter on the Capitoline Hill. Here, Romans worshipped him alongside Juno and their daughter Minerva. On the roof was a chariot drawn by four horses with Jupiter himself as the charioteer. Temples to Jupiter and Juno were commonly built by the Romans at the center of new cities in their colonies. Jupiter remained Rome's “king of the gods” until the era of Christianity.
