[1] In ancient Turkic folk religion and myth, Yalçuk is the divine embodiment of the Moon.
She is often presented as the female complement of the Sun (Koyash) conceived of as a god.
Yalchuk is said to have lived on a mountain top in a house with seven stories,[2] from which she controlled the fate of the world.
Yalchuk is often depicted driving a two-yoke chariot, drawn by horses or oxen.
Often a crescent moon rests on her brow, or the cusps of a crescent moon protrude, horn-like, from her head, or from behind her head or shoulders.
