What is "anpao"

In Sioux mythology (a Native American mythological tradition that includes Lakota mythology), Anpao ( Lakota: aŋpáo), or Anp, is an entity with two faces that represents the spirit of the dawn.

Anpao dances with Han, a primordial spirit of darkness, to ensure that Wi does not burn up the Earth, resulting in day and night.

George Bushotter ( Yankton Dakota- Lakota, 1860–1892) wrote that when his younger brother was ill, the brother was told to pray to Anpao, the Dawn, and recovered.

Anpao zi is the "yellow of the dawn," which oral history described as the meadowlark's breast.
