Chernobog is the "bad guy" of Slavic mythology. He was depicted as a humanoid idol painted black with a silvered mustache.
According to Helmold's Slavic Chronicle, Chernobog is a navy, an “evil” god. In the Serbo-Lusatian pantheon named A. Frenzel (1696) - Czernebog. His main opponent is Sventovit.
Al-Masudi in the tenth century gives a description of the sanctuary of a certain god on the black mountain: “… in it (the building on the black mountain) they (the Slavs) had a large idol in the form of a man or Saturn, represented as an old man with a crooked stick in his hand, with which he moves the bones of the dead from the graves. Under the right foot there are images of dissimilar ants, and under the left - black ravens, black wings and others, as well as images of strange Khabash and Zandzhians (ie Abyssinians)."
Peter Albin in the "Misney Chronicle" says: "For this purpose the Slavs venerated Chernobog as an evil deity, that they imagined that all evil was in his power, and therefore asked him for mercy, they reconciled him, so that in this or the afterlife not he did them harm."
Helmold also wrote that when Chernobog was honored at a feast among the Slavs, then when carrying off the guests with a bowl, each pronounced curses, and not words of blessing. However, everyone understands to the best of his upbringing: “The amazing superstition of the Slavs, because at their festivals and feasts they carry a circular cup, exclaiming words over it - I will not say blessings, but curses, in the name of the good and evil gods, as they expect from a good god happy lot, and from evil - unhappy; therefore, the evil god is even called in their own language the devil or Chernobog."
According to the myth cited by Sreznevsky, Chernobog will rot the soul of a man created by God, in fact, according to Christian dogmas, this is so. According to another myth, cited by Afanasyev, Satan (Chernobog) created man from the sweat of God.
There is a similar myth in the Laurentian Chronicle. Chernobog is the co-creator of the World. In the mythology of the Balts, the black god is called Vielona, Wellns or Vels, which actually means "devil", "devil" - he is a constant opponent of the Thunder God and the owner of the world of the dead.
