Augustalia

The Augustalia, also known as the Ludi Augustales ("Augustan Games"), was a festival celebrated October 12 in honor of Augustus, the first Roman emperor.

[2] Until Augustus died in 14 AD, Fortuna Redux was the recipient of the day's religious honors, and the name Augustalia does not appear in sources before that time.

[4] Augustus lists the establishment of the festival in his posthumously published first-person account of his achievements (Res Gestae),[5] emphasizing that it takes its name from his cognomen.

Roman festivals were often named for the deities they honored (Neptunalia for Neptune, Cerealia for Ceres), and the unstated implication was that Augustus was to be accorded divine status.

The Augustalia, abbreviated as AVG, appears on calendars in large, capital letters like some of the oldest festivals for deities of Rome's archaic religion.
