Habaek vs Yuhwa

The River Earl, water god of the Amnok (Yalu) region and father of Yuhwa, who tests Haemosu's divine claim in a contest of transformations and is claimed by Goguryeo's kings as the founder's maternal grandfather.

No origin is told; he is the lord of the river when the myth begins.

The Gwanggaeto Stele (414 CE) opens by declaring that the founder, King Chumo, was the son of the Heavenly Emperor and that 'his mother was the daughter of Habaek', and when Chumo reaches a river he cannot cross, he calls out that he is the son of heaven and grandson of Habaek. The river god's lineage was thus part of the Goguryeo royal claim from the earliest written record.

The daughter of Habaek, the River Earl, who is seduced and abandoned by Haemosu, banished by her parents, sheltered by King Geumwa of East Buyeo, and there lays the egg from which Jumong hatches; later worshipped by Goguryeo as a mother goddess.

Eldest daughter of Habaek, the River Earl (Samguk Sagi; Dongmyeongwang-pyeon).

In the *Samguk Sagi*, King Geumwa of East Buyeo finds Yuhwa south of Mount Taebaek at Ubalsu, where her parents have banished her after her union with Haemosu. He shuts her in a room, where sunlight follows her even when she moves away from it, and she conceives. She lays an egg as large as five measures of grain. Geumwa has it thrown to dogs and pigs, which will not eat it; left on the road, where horses and cattle step around it; and in the fields, where birds cover it with their wings. He cannot break it and returns it to her, and a boy breaks out: Jumong.
