Pax Ring

Pax (Latin word for Peace) was the Roman goddess of peace, the equivalent of the Greek Eirene. It first appeared on coins in the year of Julius Caesar’s death.
She was then recognized as a goddess during the reign of Augustus in order to restore peace to the empire, and an altar, named Ara Pacis, was erected for this purpose.
In Roman mythology, she is the daughter of Jupiter and Iustitia (Justice), and her equivalent in Greek mythology is the goddess Eirene.
