Gaius Octavius, known also as Augustus, during his rule followed divination regarding certain days. He never left he city on the day after the day of the fairs. He also did not start anything in Nonae, explaining that he was willing to “avoid the bad omen from the name”. Nona in Roman mythology was the name of one of the Moirai – Clotho (Greek mythology), spinning thread of human life, and at the same time a goddess helping the nursing.
Nona was the name reserved for the fifth day of the 29-day month or the seventh day of the 31-day month. According to Roman calculus, Nony fell for nine days before the Ides (15th of the month). The name of the term comes from here – from nonus (ninth). The calculations were dependent on the phases of the moon.
