In Roman mythology, Pietas was the goddess of duty to one's state, gods and family and a personification of the Roman virtue of pietas. One of the di indigetes, her main temple was a 2nd century BC one in the Forum Holitorium. This goddess was often depicted on the reverses of Roman Imperial coins with women of the imperial family on the obverse, as an appropriate virtue to be attributed to them (eg Flavia Maximiana Theodora, right). The imperial women might even appear in the goddess's guise (eg Livia here and Salonina Matidia here).
