Arch of Constantine
The Arch of Constantine is a triumphal arch in Rome, situated between the Colosseum and the Palatine Hill. It was erected by the Roman Senate to commemorate Constantine I's victory over Maxentius at the Battle of Milvian Bridge in 312. Dedicated in 315, it is the largest Roman triumphal arch. The arch spans the Via triumphalis, the way taken by the emperors when they entered the city in triumph.
Though dedicated to Constantine, much of the decorative material incorporated earlier work from the time of the emperors Trajan (98–117), Hadrian (117–138) and Marcus Aurelius (161–180), and is thus a collage. The last of the existing triumphal arches in Rome, it is also the only one to make extensive use of spolia, reusing several major reliefs from 2nd century imperial monuments, which give a striking and famous stylistic contrast to the sculpture newly created for the arch. This earned it the derisive nickname of Cornacchia di Esopo Aesop's Crow.
The arch is 21 m high, 25.9 m wide and 7.4 m deep. It has three archways, the central one being 11.5 m high and 6.5 m wide and the lateral archways 7.4 m by 3.4 m each. Above the archways is placed the attic, composed of brickwork reveted (faced) with marble. A staircase within the arch is entered from a door at some height from the ground, on the west side, facing the Palatine Hill. The general design with a main part structured by detached columns and an attic with the main inscription above is modelled after the example of the Arch of Septimius Severus on the Roman Forum.
Symbolism
Whatever the faults of Maxentius, his reputation in Rome was influenced by his contributions to public building. By the time of his accession in 306 Rome was becoming increasingly irrelevant to the governance of the empire, most emperors choosing to live elsewhere and focusing on defending the fragile boundaries, where they frequently founded new cities. This factor contributed to his ability to seize power. By contrast Maxentius concentrated on restoring the capital, his epithet being conservator urbis suae (preserver of his city). Thus Constantine was perceived amongst other things as the deposer of one of the city's greatest benefactors, and needed to acquire legitimacy. Much controversy has surrounded the patronage of the public works of this period. The German philosopher, Walter Benjamin observed that history is seen through the eyes of the victor (Über den Begriff der Geschichte VII, 1940), and Constantine and his biographers were no exception. Issuing a damnatio memoriae he set out to systematically erase the memory of Maxentius. Consequently, there remains considerable uncertainty regarding the patronage of early fourth century public buildings, including the Arch of Constantine, which may originally have been an Arch of Maxentius.
Main section
The general layout of the main facade is identical on both sides of the arch, consisting of four columns on bases, dividing the structure into a central arch and two lateral arches, the latter being surmounted by two round reliefs over a horizontal frieze. The four columns are of Corinthian order made of Numidian yellow marble (giallo antico), one of which has been transferred into the Basilica di San Giovanni in Laterano and was replaced by a white marble column. The columns stand on bases (plinths or socles), decorated on three sides. The reliefs on the front show Victoria, either inscribing a shield or holding palm branches, while those to the side show captured barbarians alone or with Roman soldiers. Though Constantinian, they are modelled on those of the Arch of Septimius Severus (and the destroyed Arcus novus), and may be considered as a "standard" item.
The pairs of round reliefs above each lateral archway date to the times of Emperor Hadrian. They display scenes of hunting and sacrificing: (north side, left to right) hunt of a boar, sacrifice to Apollo, hunt of a lion, sacrifice to Hercules. On the south side, the left pair show the departure for the hunt (see below) and sacrifice to Silvanus, while those on the right (illustrated on the right) show the hunt of a bear and sacrifice to Diana. The head of the emperor (originally Hadrian) has been reworked in all medallions: on the north side, into Constantine in the hunting scenes and into Licinius or Constantius I in the sacrifice scenes; on the south side, vice versa. The reliefs, c. 2 m in diameter, were framed in porphyry; this framing is only extant on the right side of the northern facade. Similar medallions, of Constantinian origin, are located on the small sides of the arch; the eastern side shows the Sun rising, on the western side, the Moon. Both are on chariots.
The spandrels of the main archway are decorated with reliefs depicting victory figures with trophies (illustrated below), those of the smaller archways show river gods. Column bases and spandrel reliefs are from the time of Constantine.
