Juno was worshipped under many names and with different functions:
- Juno Regina
- Juno the Queen was a member of the Capitoline Triad. She had a temple on the Aventine Hill and one in the Campus Martius.
- Juno Moneta
- The epithet is of uncertain origin. Moneta could be derived from mons, hill, or from monere, to warn. In the last case refers to the sacred geese of Juno that warned the Romans when the Gauls tried to take the Capitolium in 390 BCE. Later a mint was established in the Temple of Juno on the Capitoline Hill, thus giving us the word ‘moneta’, money. The epithet might also be explained the other way around, from the fact there was a mint in the temple. The Temple of Juno Moneta stood on the Arx of the Capitoline Hill, where the church of S. Maria Aracoeli and the Vittoriano now stands.
- Juno Sospita
- Juno the Savior was the patron goddess of the state. The Temple of Juno Sospita was in the Forum Holitorium in Rome. Her festival was on February 1st.
- Juno Curitis or Juno Quiritis
- Juno the protector of spearmen. She was the only deity to be worshipped by all 30 curiae, the military and administrative units introduced by Romulus. Her temple was on the Campus Martius.
- Juno Lucina
- Juno Lucina was the goddess of light and childbirth, in the sense of “coming to light”. A Temple of Juno Lucina was built in the Esquiline Hill 375 BCE.
The first of each month, the kalends, was sacred to Juno.
