In the older Slavic mythology, Zorya Polunochnaya represents the Midnight Star, while her sisters Zorya Utrennyaya and Zorya Vechernyaya represent the Morning and Evening Stars, the Triple Goddess of Heaven, which is much older than their service to Dažbog. Zorya (alternately, Zora, Zaria, Zarya, Zory, Zore, "Dawn"; Zorza in Polish, Zara-Zaranica (Belarusian: Зара-Зараніца, Russian: Заря-заряница Красная девица, "Dawn the Red Maiden"), Zvezda, Zwezda, Danica, "Star") are the two guardian goddesses, known as the Auroras. They guard and watch over the winged doomsday hound/gryphon, Simargl, who is chained to the star Polaris in the constellation Ursa Minor, the "little bear". If the chain ever breaks, the hound will devour the constellation and the universe will end. The Zoryas represent the morning star and the evening star.
The Zoryas serve the sun god Dažbog, who in some myths is described as their father. Zorya Utrennyaya, the morning star, opens the gates to the god's palace every morning for the sun-chariot's departure. At dusk, Zorya Vechernyaya—the evening star—closes the palace gates once more after its return.
The morning star is Zorya Utrennyaya (from Russian utro, meaning "morning"; also known as Zvezda Danica, Zvezda Dennitsa, Zwezda Dnieca, Zvezda Zornitsa, Gwiazda Poranna, Rannia Zorya, Zornica, Zornička, Jitřenka), who opens the gates of Dažbog's palace each morning so that the Sun may begin his journey. She is a patroness of horses, protection, exorcism, and the planet Venus, and Slavs would pray to her each morning as the sun rose.
Conflicting accounts exist of her marital situation. In some myths, she is described as the wife of Perun and would accompany her husband into battle. In this role she was known to protect those warriors she favoured against death by letting down her veil. In other accounts, both she and Zorya Vechernyaya were the wives of the male Myesyats, the moon god, and by him bore all of the stars. However, some have both Zorya as virgin goddesses, while describing Myesyats as an unrelated female moon goddess.
The evening star is Zorya Vechernyaya (from Russian vecher, meaning "evening"; also known as Večernya Zvyezda, Večernya Zvezda, Zvezda Vechernaya, Zorya Vechernyaya, Zwezda Wieczoniaia, Zwezda Wieczernica, Zvezda Vechernitsa, Gwiazda Wieczorna, Vechirnia Zorya, Večernyača, Večernica, Večernice), who closes the palace gates at dusk, after sunset and Dažbog's return. She was associated with the planet Venus or Mercury. Some myths described both her and her sister Zorya Utrennyaya as the wives of the moon god Myesyats and the mothers of the stars, but other accounts cast both Zorya as virgin goddesses.
