Juno
Protector and special counselor of the Roman state and queen of the gods. She is a daughter of Saturn and sister (but also the wife) of the chief god Jupiter, and the mother of Juventas, Mars, and Vulcan.
As the patron goddess of Rome and the Roman empire she was called Regina ("queen") and, together with Jupiter and Minerva, was worshipped as a triad on the Capitol (Juno Capitolina) in Rome. As the Juno Moneta (she who warns) she guarded over the finances of the empire and had a temple on the Arx (one of two Capitoline hills), close to the Royal Mint.
The primary feast of Juno Mucina, called the Matronalia, was celebrated on March 1. On this day, lambs and other cattle were sacrificed to her. Another festival took place on July 7 and was called Nonae Caprotinae ("The Nones of the Wild Fig").
The month of June was named after her. She can be identified with the Greek goddess Hera and, like Hera, Juno was a majestical figure, wearing a diadem on the head. Juno is also the protecting and guardian spirit of females. She is the Great Mother, Goddess of Fate. Preserver, Queen of Heaven, the Celestial Light. Her totem is the Peacock; her flower is the Lily. Pomegranate and figs are her fruits; malachite her stone and lilies sprang from her milk.

Justitia
The Roman goddess of justice, portrayed as a woman holding a cornucopia and scales. Later she is portrayed with a blindfold, holding scales and a sword (or scepter).

Juturna
The Roman goddess of wells and springs, sister of Turnus (the king of Rutuli) whom she supported in his battle against Aeneas. Jupiter turned her into a nymph and gave her a well near Lavinium in Latium. She also gave her name to a well near the Vesta-temple of the Forum Romanum, called the Lacus Juturnae. The water from this well was used for the state-offerings. Also, the Dioscuri were thought to have watered their horses here. She is the mother of Fontus (Fons) and wife of Janus.

Juventas
("youth"). An early Roman goddess of youth, equal to the Greek goddess Hebe. Boys offered a coin to her when they wore a man's toga for the first time. The temple of Juventas on the Capitol was more ancient than that of Jupiter. She also had a second temple in the Circus Maximus.
