Eusebia (Greek: Εύσέβεια) is a concept from ancient Greek religion that is roughly equivalent to, and often translated as, piety. Derived from the roots eu- (Εύ = good) and seb- (σέβ, a root pointing to danger and flight), the concept describes a healthy fear of the gods.
In Greek mythology, the concept of Eusebia is anthropomorphized as the daemon of piety, loyalty, duty and filial respect. According to one source, her husband is Nomos (Law), and their daughter is Dike, goddess of justice and fair judgment. In other tellings, Dike is the daughter of the god Zeus and/or the goddess Themis (Order).
