Chiapas, Mexico's southernmost state bordering with Guatemala was part of the ancient Maya cultural region and today is home to several ethnic groups who speak dialects of the Maya language. Pre-Lenten Carnival in the highland region is celebrated with monkey masks, tigre masks, and clown masks. The feast day of San Sebastian is an important occasion in the central valley of the state among the Zoque people of Suchiapa and Chiapa de Corzo who perform the dance-drama known as Los Parachicos. In this dance, dating back to colonial times to bless the children, hundreds of dancers wear elegant costumes with finely carved masks with European features and in Suchiapa some dancers wear finely carved bull masks. Both forms of masks get worn with an unusual wig made of tightly knotted sisal. Also from Suchiapa we see finely carved tigre helmets worn for Corpus Christi.
