Kummattikali is the famous colorful mask-dance of Kerala, South Malabar in particular. During the festival of Onam, Kummattikali performers move from house to house collecting small gifts and entertaining people. Kummatti dances are rampant in the Thrissur district during Onam. Pristine or original form of Kummattikali can be seen in the Bhadrakali temple in Palghat district.
The costumes are a most interesting facet of Kummattikali. The dancers don a heavily painted colourful wooden mask depicting faces of Krishna, Narada, Kiratha, Darika, or hunters. These masks are usually made out of saprophyte, jack fruit tree, Alstonia scholaris, Hog Plum tree or the Coral tree.
The dancers wear skirts woven out of plaited grass. Some cover their whole body with bunches of grass for a more bushy appearance. The semblance is made more joyful with the 'talla' attached externally to the mask giving the appearance of a toothless open mouth. Dancers also hold and manipulate long sticks of residuary agricultural produce called 'Kummattikali': it is from this that the dance derives its name. Their dance is related to Shaiva myth. 'Thamma' (an old woman) walks in front with the help of a stick. Thamma is symbolic of mother of every being and everything.
Kummatti dancers are a sight to watch as they move around from house to house collecting jaggery, rice, or small amounts of cash. Onlookers, specially children take great delight in their performance.
The rhythm for the dance movements is provided by vibrating the string of a bow like instrument called an Onavillu. Areca nut wood is used to make the bow and the strings are beaten with a narrow bamboo stick. The themes of Kummattikali are mostly taken from the stories of Ramayana, Darika Vadham, the story of Shiva and folk tales like Manjan Nayare Pattu.
