Mengdu

Set of ritual devices, such as knives, a bell and divination implements

The mengdu, also called the three mengdu and the three mengdu of the sun and moon, are a set of three kinds of brass ritual devices—a pair of knives, a bell, and divination implements—which are the symbols of shamanic priesthood in the Korean shamanism of southern Jeju Island. Although similar ritual devices are found in mainland Korea, the religious reverence accorded to the mengdu is unique to Jeju.
