The representation of the Concordiae Apostolorum is one of the most important iconographic elements created in the second half of the 4th century. The reform that Pope Damasus initiates with the veneration of the cult of martyrs in Rome elevates the importance that the two apostles had. Namely, according to apocryphal literature, Peter and Paul worked together in spreading the gospel in Rome, where they were eventually tortured and killed, which makes them ideal protectors of the city. The apostolic authority that Peter and Paul enjoyed in Rome led to them being declared the founders of the church in Rome, but also of the city itself, replacing the mythical founders Romulus and Remus. Then the church begins to present them in an almost propaganda like style in a jointly concordia in order to emphasize their commonality as well as the unity of the state and the church. Then the reconstruction of the empire with Christianity as the main religion actually begins. The iconography of Peter and Paul was primarily developed in Rome, but it also spread throughout Italy, later also in Constantinople and North Africa. Since the concordia is a display that was supposed to promote a certain message, it had to be present as much as possible in the everyday life of citizens. Thus, there are various objects on which we find the representation of the apostolic concord, such as: gold glasses, ceramic objects, objects made of bronze or silver, stone monuments and objects made of ivory. In addition to the depiction of the concord, Peter and Paul also appear in Christocentric scenes in the 4th and 5th centuries, such as traditio legis, traditio clavium and maiestas Domini.
