Seolmundae Halmang

Lore & Background

Seolmundae Halmang is attested to in the 18th-century texts Pyohaerok and Tamnaji, as well as in oral tradition. Pyohaerok possibly contains the oldest known mention of her, where people prayed to a goddess called Seonma Seonpa, who likely corresponds to her. Some legends say she was a filial daughter of the Jade Emperor, though she descended from the heavens to create Jeju against her parents' will.

She is described as fantastically giant. When she laid down, using Hallasan as her pillow, her toes reached Gwantalseom. No matter what body of water she stood in, the water never rose above her knees. She created Jeju Island by gathering dirt in her chima (Korean skirt) and pouring it into the sea, forming the around 360 oreum (small extinct volcanoes). The last volcano she created was Hallasan; its top was so sharp it fell off, forming Sanbangsan, and the hollowed crater became Baengnokdam.

She once offered to build a bridge to the mainland if the people made her one set of undergarments, but they fell short, so the bridge remains unfinished off Jocheon-eup. Several legends describe her death: trapped in a swamp on Hallasan, falling into a pot of juk (rice porridge) she was preparing for her 500 sons (who then became the 500 Yeongsil Rocks), or drowning near Seogwipo.

Reader's Guide

Seolmundae Halmang holds a central place in Jeju Island's cultural and mythological identity, serving as a creator figure whose actions explain the island's distinctive landscape. Her stories, preserved in 18th-century texts and oral tradition, blend divine and human traits, including mortality, which sets her apart from many creator deities. The diversity of her name spellings—over a dozen variants—reflects the oral nature of her tradition and the island's linguistic history. Her giant stature and earth-moving feats, such as forming Hallasan and the oreum, provide etiological explanations for Jeju's volcanic terrain. The legend of the unfinished bridge highlights a reciprocal relationship with humans, while her multiple death stories underscore her mortality. Her possible male counterpart, Seolmundae Hareubang, was likely invented after her, suggesting her primacy. As a figure in Jeju shamanism, she embodies the island's unique blend of myth, folklore, and geological wonder, remaining a key symbol of Jeju's heritage.
