The Arch of Constantine is located next to the Colosseum. This was built to commemorate Constantine’s victory over Maxentius at the battle of Milvian Bridge. The arch is 21 meters high and 25.9 meters wide with three archways. It is said that parts have been reused. These reused items visually transferred the old Roman virtues of strength, courage, and piety. Four Corinthian style pillars divide the layout of this arch. There are many reliefs across this entire arch. Some represent victory and others represent hunting and sacrificing. One of the main parts of this arch is the frieze running around the monument under the round panel, which depicts scenes from the campaign of Constantine against Maxentius.
Church of Santa Costanza-
Central plan is the Roman building with vertical axes served as models for Christian tombs, martyrs’ churches, and baptizers. It was a church built in Rome under Constantine I. It was a place of burial for his daughters Constantina and Helena. This building is of a circular structure measuring 29 meters in diameter with twelve pairs of columns. It is decorated in marble and mosaics. The mosaics represent both pagan and early Christian origin.
The Early Roman style reflected elements by the Etruscan and the Greeks. The development of proportional human figures became the new way of painting. A lot of Roman art was through their architecture while Christian art was through religious paintings. Many Christian painting included images of Jesus and narrative scenes of Christ's life. This religious hierarchy came about when the Western Roman Empire's political structure collapsed after the Fall of Rome. Like Roman Art, Christian art styles of representation was entirely drawn form wealthier Pagans. Before the edict of Milan, Christian art was restricted to the decoration of hidden places of worship. Most of the early religious artist derived from Roman art but chose to reject the ideals of perfection in form and technique.
