Ara Pacis Augustae (Altar of Augustan Peace)

» Unknown artist(s), Rome

In the summer of 13 BCE, the Roman senate issued a decree calling for the construction of an outdoor altar complex commemorating the emperor Augustus’s successful campaigns in Spain and Gaul and his return to Rome in that year.

The Ara Pacis Augustae, or Altar of Augustan Peace, was completed in 9 BCE.

The altar complex consisted of an interior altar surrounded by a stone precinct wall. The entirety was raised on a marble base with steps leading into the precinct space. Both the altar proper and its enclosing structure were heavily ornamented with relief carving. The iconography of the exterior program included references to fertility and prosperity, such as vegetation and animals, in the lower register and scenes associated with Rome’s mythic past in the upper. Most scholars identify narrative panels on either side of the west entrance to the altar as depictions of Rome’s founding figures—Aeneas to one side, Romulus to the other. These figures, in turn, are seen as prototypes for Augustus himself.

Processional friezes along the north and south sides of the outer wall are thought to represent the sacrificial procession that took place annually at the altar by order of the senate. They have also been interpreted as depictions of the altar’s dedication ceremony. In either case, it has been observed that the movement of the figures in these relief carvings would have echoed that of visitors as they moved around the monument.

Originally, the Ara Pacis stood adjacent to other structures associated with Augustus, namely the emperor’s mausoleum, the largest Roman tomb at the time, and the Horologium-Solarium, a huge sundial marked with references to Augustus’s birth and accomplishments. The three monuments were all situated on the north end of Rome’s Campus Martius. This land just outside the city proper was considered sacred and appropriated by Julius Caesar. As Augustus continued and expanded public works projects initiated under Caesar, power shifted away from old Republican Rome toward the Campus. Situated in this park-like setting beside the Via Flaminia, one of the principal roads into the city, the Ara Pacis celebrated imperial power as part of a larger urban complex declaring the civic largess of Rome’s emperors.
