Juno was originally an ancient Italic deity. Ancient titles describe her as Juno Lucetia, goddess of celestial light (she was also worshipped as a moon goddess) and Juno Lucina (identified with the Greek goddess Eileithyia), goddess of childbirth, she who brings newborn into the light. In the Roman pantheon Juno was the chief female divinity and consort of Jupiter. Over time she was identified with the Greek goddess Hera. On Roman coins Juno is usually portrayed holding a patera; a sceptre or sometimes a small statuette of Athena, and she is often accompanied by a peacock.

Various other titles depict her as Juno Pronuba (protectress of marriages); Juno Regina (queen and member of the Capitoline triad); Juno Sospita (protectress of confinements, who assists those in need).
Juno Moneta originally guided those to be married, and was later associated with money, due to the proximity of a mint near her temple on the Capitoline hill. On coins Juno Moneta appears as the protectress of finance (right). She usually holds a scale and a cornucopia as indication of a just balance and abundance in financial matters.

Juno frequently appears on coins of Roman empresses. Juno Lucina, protectress of childbirth and midwives is depicted on the reverse of this rather worn sestertius of Faustina Minor (below right). Here Juno is standing between two children, holding a third. Juno Lucina is usually portrayed in the company of children, she is either holding a child or standing next to children. Other attributes include a patera; a sceptre; and often a flower, the latter alluding to the circumstances in which she conceived Mars. Juno Lucina had a temple on the Esquiline since 735 BC and her festival, the Matronalia, was celebrated each March.
