The Zoryas were the dawn-maidens of the Slavic sky — three sisters, in the most common East Slavic accounts, who attended the sun's daily journey. Zorya Utrennyaya was the morning star, who opened the gates of heaven each dawn for the sun's chariot to come forth; Zorya Vechernyaya was the evening star, who closed the gates again at sunset; and a third sister, Zorya Polunochnaya, watched at midnight while the sun was beneath the earth. They were the daughters (in some versions) of Dazhbog the sun-god and the consorts of various warrior figures of the heroic legends.
The Zoryas had also a darker function. There was at the constellation Ursa Minor — the Little Bear — a great hound, chained by an iron chain to the celestial pole; this hound was constantly trying to break free, gnawing at the chain. If the chain ever broke, the hound would devour the constellation Ursa Major, and after it the sun, and the world would end in a great darkness. The Zoryas were charged with watching this hound and with keeping the chain mended; their nightly vigil at the pole was a cosmological necessity, by which the world's continuance depended on their watchfulness.
The figure of the Zoryas is one of the most distinctively Slavic divine groupings — the function (dawn-maidens), the number (three), the relationship to the sun, are all paralleled in other Indo-European pantheons (the Vedic Ushas, the Baltic Aušrinė), but the specific cosmological role of guarding the chained doomsday-hound is, so far as we know, uniquely Slavic.
