Chronicles

From Slavic.info

The Slavic gods mentioned in the chronicle of a monk Nestor (about 1100 A.D.) included Perjunes or Perun (the Thunder, or the Sky), the chief diety, personifying the lightning and the thunder; Svarog, the heavens, and the earth as the wife of Perun. The god of fire was Dabog or Dai-bog (the god of sun and sunshine, the giver of life and of all good things, the god of prosperity, light and every progress) and Stribog (a hostile deity, god of storms or winds) ; Mokosh was a Venus, and Simargi the god of ocean, Veles, Voles or Volos, "the beast god," may have been a god of cattle (herds) and patron of merchants. In the Song of Igor's Band he is said to be the grandfather of boiany or bards. Chors or Khors was a Mars. Perun curses those who break their oaths; and weapons and gold are dedicated to him. His images were of wood, with a silver head and golden mustaches.
