Religio

religio might be translated better as "religious scruple" than with the English word "religion".^[19] One definition of religio offered by Cicero is cultus deorum, "the proper performance of rites in veneration of the gods."^[20]

Religio among the Romans was not based on "faith", but on knowledge, including and especially correct practice.^[21] Religio (plural religiones) was the pious practice of Rome's traditional cults, and was a cornerstone of the mos maiorum,^[22] the traditional social norms that regulated public, private, and military life. To the Romans, their success was self-evidently due to their practice of proper, respectful religio, which gave the gods what was owed them and which was rewarded with social harmony, peace and prosperity.
