Pietas, translated variously as "duty", "religiosity" or "religious behavior", "loyalty", "devotion", or "filial piety" (English "piety" derives from the Latin), was one of the chief virtues among the ancient Romans. It was the distinguishing virtue of the founding hero Aeneas, who is often given the adjectival epithet pius ("religious") throughout Vergil's epic Aeneid. The sacred nature of pietas was embodied by the divine personification Pietas, a goddess often pictured on Roman coins. The Greek equivalent is eusebeia (εὐσέβεια).
