Dayang Sumbi, also called Rarasati, is the tragic heroine of the Sangkuriang legend of West Java. In the fullest Sundanese tellings she is of half-divine birth, daughter of King Sungging Perbangkara and a goddess enduring a curse in the shape of the wild sow Wayungyang, and her unfading youth and beauty set the tale's machinery in motion. Withdrawn to a hilltop to weave, she idly vowed to marry whoever retrieved her fallen shuttle; it was fetched by Tumang, a god cursed into the body of a dog, who became her husband and the father of her son Sangkuriang. After the boy killed Tumang on a hunt and she struck his head in grief, mother and son were parted, and when the grown Sangkuriang returned and wooed the ageless woman, only the old scar betrayed him. To escape the marriage she demanded a lake and a boat built in one night, then defeated the attempt by spreading her luminous white cloth, the boeh rarang, so that the eastern sky glowed like daybreak. Interpreters from R.W. van Bemmelen, who linked the story to the volcanic history of the Bandung basin, to Jakob Sumardjo, who reads her weaving and vigilance as emblems of cosmic order, have kept her at the centre of Sundanese mythological studies.
