Stribog is a god in Slavic mythology found in three East Slavic sources, whose cult may also have existed in Poland. The sources do not inform about the functions of the god, but nowadays he is most often interpreted as a wind deity who distributes wealth.
Stribog appears for the first time in the 12th-century Primary Chronicle together with other gods for whom Vladimir the Great erected statues:
And Vladimir began to reign alone in Kyiv, and he set up idols on the hill outside the castle: one of Perun, made of wood with a head of silver and a moustache of gold, and others of Khors, Dazhbog, Stribog, Simargl, Mokosh. The people sacrificed to them, calling them gods. They brought their sons and daughters and sacrificed [them] to demons. They desecrated the earth with their offerings. And the land of Rus and the hill were defiled with blood. But the gracious God desires not the death of sinners. Upon that hill now stands the church of Saint Basil, as we shall later narrate.
И нача княжити Володимеръ въ Киевѣ единъ, и постави кумиры на холму внѣ двора теремнаго: Перуна дрезяна, а главу его сребрену, а усъ златъ, и Хърса, Дажьбога, и Стрибога и Симарьгла, и Мокошь. И жряху имъ, наричюще я богы, и привожаху сыны своя и дъщери, и жряху бѣсомъ, и оскверняху землю требами своими. И осквернися кровьми земля Руска и холмо-тъ. Ио преблагий богъ не хотя смерти грѣшникомъ, на томъ холмѣ нынѣ церкви стоить, святаго Василья есть, якоже послѣди скажемъ.
In The Tale of Igor's Campaign, the winds are called Stribog's grandsons:
Now the winds, sons of Stribog, blow from the sea like arrows on the valiant campaign of Igor.
Се вѣтри, Стрибожи ⟨/Стьри-?⟩ вънуци, вѣють съ моря стрѣлами на храбрыѣ ⟨хоробрыѣ⟩ пълкы Игоревы.
The word of John Chrysostom also mentions Stribog:
Oh, perfidious devil’s deceit, not even pagans would do it! And others believe in Stribog, Dazhbog and Pereplut, for whom they drink from horns while cavorting, having forgotten God who created heaven and earth, the seas and rivers. And this way they rejoice in their idols.
