Do ceremonial mask.The Islamized communities of the Ligbi and of the Jimini who live as traders and artisans among non-Muslim groups in extensive areas of northern Côte d'Ivoire are known for an institution called Do or Lo, one of whose most striking public manifestations is colorful masquerade dancing. Their masks are danced during the funerals of distinguished Muslim holy men, and their performances also mark critical moments during the Muslim calendar year, and at the end of Ramadan, the month-long Islamic fast. The masqueraders are greatly admired for the grace of their dance movements, which they perform in pairs and in perfect unison. The performance of the maskers is accompanied by drums, singing and dancing. Prayers and sacrifices alternate for a full week before the assembled village.
