The Carnival of Ottana is one of the most distinctive and fascinating in the Mediterranean area. The origins and meaning of its masks are unclear; they have undoubtedly been passed down through centuries and represent an ancient ritual spanning thousands of years. Among the celebrations held in the town, the first of the year is that of Saint Anthony, marked by the lighting of the fire. At dusk on the eve of Saint Anthony the Abbot (January 16), following the fire blessing, the traditional masks, generally known as Merdules, make their so-called Prima Essia, or first appearance of the year. In front of the large bonfire called S’Ogulone, after the religious rites, the Merdules initiate the Carnival preparations. Carnival rituals continue with Saint Sebastian and Candlemas and are repeated every Saturday and Sunday until the three main days of Carnival. This is a beloved and eagerly awaited event for all the people of Ottana. It is an important time of togetherness, filled with fascination and ancient significance. During the first two days of Carnival, it is customary for the Merdules to be invited by those not wearing masks; on Tuesday, the Merdules, in turn, invite the unmasked. Shrove Tuesday marks the day when, toward evening, Sas Amoradas are sung—improvised octaves dedicated to young women—and it is also the final day of Carnival.
