Most Khon masks are rather like helmets reaching down to the neck.

Traditionally these Khon masks were used in classical Thai theater, and each mask depicts a specific epic, legendary or mystical character. 'Khon' is the name of the famous masked dance-drama, is performed by dancers wearing brilliantly crafted masks.

During the Ayutthaya period, 'khon' performances were held in palace halls or courtyards lighted by torches. Normally, khon performances are taken from different episodes in the Ramakien, the Thai version of the Indian epic, the Ramayana. The formal movements of 'khon' performances make the acting and dancing inseparable. More than ten styles of mask identify the characters of the dancers as kings, demons or monkeys. Lord Ram wears green, for example, Lord Lak wears gold and the monkey, Hanuman, wears white.
