About: Religio

The Latin term religiō, the origin of the modern lexeme religion (via Old French/Middle Latin), is of ultimately obscure etymology. It is recorded beginning in the 1st century BC, i.e. in Classical Latin at the end of the Roman Republic, notably by Cicero, in the sense of "scrupulous or strict observance of the traditional cultus". In classic antiquity, it meant conscientiousness, sense of right, moral obligation, or duty towards anything and was used mostly in secular or mundane contexts.
