Sanni Masks ෴ සන්නි වෙස් මුහුණු

The sanni masks are mainly used in healing ceremonies and worn by an edura (a sort of Sri Lankan artist/exorcist). Apparently, there are eighteen different Sanni masks, each specializing in curing specific illnesses.

Sanni yakuma, sometimes known as Daha ata sanniya (දහ අට සන්නිය), is a traditional Sinhalese exorcism ritual. The ritual consists of 18 masked dances, each depicting a particular illness or ailment affecting humans. These 18 dances (දහ අට සන්නිය) are the main dances of the Pahatharata, or low country, dancing form, which is one of the three main dancing forms of Sri Lanka.The ritual calls the demons who are thought to affect the patient, who are then told not to trouble humans and banished.

It was believed that illnesses were brought on humans by demons and these beliefs and rituals could have prehistoric roots. According to folklore, the 18 demons who are depicted in the Sanni Yakuma originated during the time of the Buddha. The story goes that the king of Licchavis of Vaishali suspected his queen of committing adultery and had her killed. However, she gave birth when she was executed and her child became the Kola Sanniya, who grew up "feeding on his mother's corpse". The Kola Sanni demon destroyed the city, seeking vengeance on his father, the king. He created eighteen lumps of poison and charmed them, thereby turning them into demons who assisted him in his destruction of the city. They killed the king, and continued to wreak havoc in the city, "killing and eating thousands" daily, until finally being tamed by the Buddha and agreed to stop harming humans.

Each of these demons are believed to affect humans in the form of an illnesses, and the Sanni Yakuma ritual summons these demons and banishes them back to the demon world after bringing them under control. Although it is unclear when the ritual began, it has been performed in the southern and western parts of the country since ancient times.

The name of the ritual comes from the Sinhala word sanniya meaning disease or ailment, and yakuma meaning demon ritual. In Sri Lankan culture, exorcism rituals are known as tovil. The Sanni Yakuma is possibly the best known exorcism ritual in the country. It is a mix of traditional beliefs regarding spirits with Buddhism. Before performing the healing ritual, the lead performer known as the yakadura determines whether the patient is affected by a demon, and schedules the ritual for an auspicious day and time, usually from dusk to dawn. The Edura or Yakadura is the Shaman healer and is usually a fisherman, drummer or farmer. It has two main stages, namely the Ata Paliya and Daha Ata Sanniya. The dancers are dressed in colourful attire and masks, and perform swift and complex dance steps and spins accompanied by rhythmical drum beats. Rather comic and somewhat obscene dialogues take place between the drummer and the demon on stage, in which the demon is humiliated.
