The Iunonalia or Junonalia was a Roman festival in honor of Juno, held on March 7 (the Nones). Among extant Roman calendars, it appears only in the Calendar of Filocalus (354 AD),[1] and was added to the festival calendar after the mid-1st century AD.[2]
The Junonalia is attested also in a fragmentary poem De Iunonalibus, attributed to Claudian.[3] In it, Juno is addressed as mistress of the celestial pole, and the spouse and sister of the king of heaven. Her function as a goddess of marital bonds is also noted. Although the text is conjectural at this point, she may be asked to grant a return.[4]
The Junonalia may have concluded a three-day festival begun March 5 with the Isidis Navigium, the "Sailing of Isis."[5] In the Metamorphoses of Apuleius, Isis is addressed as Queen of Heaven, and by the 2nd century a number of goddesses, including Juno, shared the epithet Caelestis.[6]
