Mengdu

What it is

The mengdu form a set of three brass ritual devices that represent the priesthood in Jeju Island shamanism. This collection includes two knives, a bell, and various divination implements. These items are not merely ceremonial; they are viewed as vessels for spiritual power. Each set is believed to hold the spirits of past human shamans who owned them. These spirits, known as mengdu ancestors, assist current practitioners in interpreting divine will. The objects are passed down through generations, linking living shamans to their predecessors and the original mythic heroes.

Where it comes from

The origin of these tools is rooted in the Chogong bon-puri, a foundational narrative of Jeju religion. The story tells of triplets born miraculously to a woman named Noga-danpung-agissi. After being abandoned and later resurrected by their sons, the triplets became divine judges. They summoned a celestial smith to forge the first mengdu implements. These objects were created to help the triplets perform rituals and save their mother from death. The physical design of each tool reflects specific events from this myth, such as the shape of the knife blades representing the mother's pregnant belly.

How it is done

Shamans use the mengdu to determine the intentions of gods during ceremonies. The knives are thrown onto the ground, and their landing positions indicate different outcomes or messages. Specific configurations, called bridges, correspond to elements in the origin myth. For example, crossed knives may signal misfortune, while other arrangements suggest discord or divine presence. The bell is rung to invite deities into the ritual space. Divination discs are also employed to read signs. The paper skirts on the knives are replaced regularly, with old strands burned ritually after use.

Tools and materials

The primary components are made of brass. The knives feature blades measuring roughly twelve centimeters and handles wrapped in paper strips. The paper skirt represents garments worn by figures in the origin myth. Serpentine etchings on the blades have disputed meanings among practitioners. The bell serves as an auditory signal for divine arrival. Divination discs bear Chinese characters for heaven, earth, and gate. These materials are chosen for their durability and symbolic resonance within the local cosmology.

What it is for

Practitioners seek the mengdu to gain authority and communicate with the spirit world. The tools help shamans diagnose illnesses believed to be caused by angry gods. They are essential for initiating new shamans, a process required to cure certain spiritual ailments. The objects also protect the practitioner and ensure the correct performance of rites. By wielding these items, shamans assert their role as intermediaries between the human community and the divine realm.

Who does it

Only initiated shamans on Jeju Island are authorized to use the mengdu. Training involves rigorous apprenticeship under established priests. The transmission of knowledge occurs through the inheritance of specific sets of tools. Each new shaman receives a set previously owned by a mentor, thereby absorbing the ancestral spirits within it. Historically, women could become shamans, though modern practices vary. The status of a shaman is closely tied to their possession and mastery of these sacred instruments.

Peoples and places

The mengdu are unique to Jeju Island, distinguishing its shamanic tradition from mainland Korean practices. While similar objects exist elsewhere, the reverence accorded to the mengdu is exclusive to Jeju. The practice is declining due to fewer initiations and an oversupply of existing sets. Some untrained individuals now create their own versions, which traditionalists view as invalid. The cultural identity of Jeju Islanders remains strongly linked to these ritual objects.

What people believe

Jeju shamanism views the mengdu as incarnations of both mythic heroes and historical shamans. The spirits within the tools actively participate in rituals, guiding the living practitioner. This belief system emphasizes continuity between past and present. The physical attributes of the objects are interpreted as reminders of mythic events. Shamans disagree on some symbolic details but agree on the core function: facilitating contact with the divine. The tools are considered alive with spiritual presence.

When it is done

The mengdu are used throughout the ritual calendar, particularly during the Great Gut sequence. The Chogong bon-puri recitation marks a key moment where these objects are honored. Initiation ceremonies require the immediate use of the mengdu to cure sinbyeong. Regular rituals involve throwing the knives to check divine favor. The timing of paper skirt replacements aligns with the start of new ceremonies rather than fixed dates.

How scholars and sceptics see it

Folklorists note the absolute faith Jeju shamans place in their knives. Researchers highlight the uniqueness of Jeju shamanism compared to mainland traditions. Studies focus on the Chogong bon-puri as the explanatory framework for all ritual objects. Scholars observe the decline in traditional practice and the rise of unofficial reproductions. Anthropological work examines how these objects maintain social and religious cohesion on the island.

Compare and confuse

Mainland Korean shamanism uses different ritual instruments, lacking the specific mengdu set. Other East Asian traditions employ bells or knives, but without the same mythic lineage. The term mengdu specifically refers to this Jeju triad. Confusion sometimes arises regarding the exact symbolism of blade patterns, which varies by region and family tradition.
