The Slavic deities were worshipped by the peoples of Eastern Europe, from Russia to the Balkans, before their Christianization. They venerated them in wooden idols and open-air sanctuaries, tied to the forces of nature and the seasons. With few written records, their beliefs survive mainly in folklore and popular traditions.
On Kupala night, the summer solstice, young people leapt over bonfires and floated flower crowns on the rivers. Maslenitsa saw off winter with pancakes in honor of the sun, and in Kiev prince Vladimir raised — and later toppled — a great idol of Perun.

At a glance
Perun (Перунъ) is the supreme warrior, judicial and celestial deity of thunder, flaming lightning, fertilizing storms, cosmic order, the sacred oak and the weapons of war in ancient Slavic mythology. Venerated with absolute preeminence by the Eastern, Western and Southern Slavs, Perun occupied the zenith of the state pantheon erected in Kiev by Grand Prince Vladimir I in 980 CE, where his monumental wooden statue displayed a gleaming silver head and solid gold moustaches on the hill overlooking the Dnieper River. As the supreme embodiment of sovereign power, Perun presided over sacred military oaths: in the peace treaties sealed between Kievan Rus and the Byzantine Empire in the 10th century CE, Russian warriors solemnly swore upon their own unsheathed swords, shields and gold arm-rings in Perun's name. Dwelling at the top of the colossal World Tree (usually pictured as an age-old oak whose roots touch the underworld and whose branches hold up the celestial vault), Perun wages an eternal, cyclical cosmic combat against the chthonic god Veles, who crawls as a monstrous serpent in the lower waters to steal cattle, water and the divine consort, and is struck down by the stone darts and fiery axes of the lord of thunder. Identified after the forced Christianization of Eastern Europe with the biblical prophet Elijah (Ilya Muromets / Saint Elijah the Thunderer), Perun embodies the indomitable force of heavenly justice, the fertility that falls with torrential rains, and the unshakable courage that defends the community against the dissolving forces of chaos. His blazing axe and his age-old oaks remain the eternal symbol of the unshakable courage that defends cosmic justice and the freedom of peoples against all forces of disorder and fear. He is the eternal sentinel of the Slavic skies, who protects the just with beneficent storms and sacred fire.
