Septimontium

The Septimontium was a pre-urban festival celebrated in ancient Rome by montani, residents of the seven (sept-) communities associated with the hills or peaks of Rome (montes): Oppius, Palatium, Velia, Fagutal, Cermalus, Caelius, and Cispius. The Septimontium was celebrated in September, or, according to later calendars, on 11 December. It was not a public festival in the sense of feriae populi, according to Varro, who sees it as an urban analog to the rural Paganalia.
