These are stage play masks handed down in Hahoe and Byeongsan villages in Andong, Gyeongsangbuk-do. They are the oldest existing stage play masks in the country. A total of 11 Hahoe Masks of the following have been handed down: two lions, a bride, a monk, a nobleman, a scholar, a chorangi (a frivolous servant), an imae (a servant for a scholar), a bune (a young married woman), a butcher, and an old woman. On the other hand, two Byeongsan Masks of a daegam (a high-ranking official) and a nobleman have been handed down. In Korea, stage masks were usually made of gourd or paper and burned at the end of the year. Note, however, that the masks used in Hohoe and Byeongsan were made of wood and preserved, displaying a sophisticated appearance. The masks were originally used at Byeolsingut (an exorcism rite held to pray for peace of the village and good crops to the village guardian deity) held during the year’s first full moon, January 15 on the lunar calendar. The masks used in Hohoe and Byeongsan were made of alder tree wood. They display exquisite colors as a result of two or three layers of lacquer painting. The chins were attached to the other parts of the mask with a string so that they could be moved up and down when the character spoke. The masks of a nobleman and a butcher in particular have a sophisticated three-dimensional appearance.
