There were two important annual celebrations: On the 16th of Audnaios, a day in January or December, the birth of the king was celebrated. On the 10th of Loos, probably the 14th of July, the coronation of the king was celebrated.
The 10th of Loos was also the day of the “Manifestation of the Great Gods”, as the inscriptions called it. On this day the daily life of Kommagene came to a halt and for two days the people joined in the celebrations on Mount Nemrud or the temene, the local sanctuaries. All these ceremonies were recorded in detail in the Nomos, which Antiochos carved on the back of the statues of both the East- and West-Terraces.
