The Ara Pacis, or the Altar of Peace, in ancient Rome was not the monochrome stone monument we see today. Originally, it was adorned with vivid colors, reflecting a common practice of the era where color was applied to sculptures and reliefs to bring them to life and convey cultural significance. Traces of blues, reds, and yellows have been found, suggesting that the altar was once a polychromatic symbol of the Pax Romana, the long period of peace initiated by Augustus. The colors likely enhanced the detailed depictions of gods, personifications, and historical figures, making the altar not just a political statement, but also a vibrant piece of public art.
