Column of Antoninus Pius in the context of "Roma (goddess)"

In ancient Roman religion, Roma was a female deity who personified the city of Rome and, more broadly, the Roman state. She was created and promoted to represent and propagate certain of Rome's ideas about itself, and to justify its rule. She was portrayed on coins, sculptures, architectural designs, and at official games and festivals. Images of Roma had elements in common with other goddesses, such as Rome's Minerva, her Greek equivalent Athena and various manifestations of Greek Tyche, who protected Greek city-states; among these, Roma stands dominant, over piled weapons that represent her conquests, and promising protection to the obedient. Her "Amazonian" iconography shows her "manly virtue" (virtus) as fierce mother of a warrior race, augmenting rather than replacing local goddesses. On some coinage of the Roman Imperial era, she is shown as a serene advisor, partner and protector of ruling emperors. In Rome, the Emperor Hadrian built and dedicated a gigantic temple to her as Roma Aeterna ("Eternal Rome"), and to Venus Felix ("Venus the Bringer of Good Fortune"), emphasising the sacred, universal and eternal nature of the empire.

Roma's official cult served to advance the propagandist message of Imperial Rome. In Roman art and coinage, she is usually depicted in military form, with helmet and weapons. In Rome's eastern provinces, she was often shown with mural crown or cornucopia, or both. Her image is rarely found in a commonplace or domestic context. Roma was probably favoured by Rome's high-status Imperial representatives abroad, rather than the Roman populace at large. She was depicted on silver cups, arches, and sculptures, including the base of the column of Antoninus Pius. She survived into the Christian period as a personification of the Roman state. Her depiction seated with a shield and spear later influenced that of Britannia, personification of Britain.
