 The characteristic myths of Rome are often political or moral, that is, they deal with the development of Roman government in accordance with divine law, as expressed by Roman religion, and with demonstrations of the individual's adherence to moral expectations "(mos maiorum)" or failures to do so.Narratives of divine activity played a more important role in the system of Greek religious belief than among the Romans, for whom ritual and cult were primary.Although Roman religion did not have a basis in scriptures and exegesis, priestly literature was one of the earliest written forms of Latin prose.
