As has been stated on the main page, Slavic mythology is still unclear to a large extent. Since we lack sources, a big part of it — pretty much the whole part about the relations between the gods — had to be reconstructed. Don't treat what is written here as a reliable source; it is perhaps closer to a quick round-up of the mythology as it is generally considered to have been, or a list of tropes one might expect of fictional appearances of the Slavic deities, together with explanations, put together for your convenience. For actual reliability, much more research would need to be done.
Major deities
The gods and goddesses described here are considered to have been the most important in Slavic pantheon, or at least the characteristic ones. Fiction (at least the up-to-date) striving to show its work in depiction of Slavic mythology will probably attempt to include some of them.In comparative mythology, Perun is a descendant of proto-Indo-European Perkwunos and a brother to figures such as Thor (mighty bearded thunderer), Zeus (supreme ruler of the sky), Indra (the Vedic Top God who wielded thunderbolts) or Baltic god Perkūnas (notice the almost unchanged name). It also appears that the Nordic rulers of Novgorod and Kiev embraced him as an equivalent of Thor, or perhaps Odin. In the syncretic Dvoyeveriye cults of Old Russia, he was worshipped as Elijah the Prophet, because Elijah is also known as, "the Thunderer."
- An Axe to Grind: The axe was the weapon commonly attributed to him.
- Elemental Powers: He's got several under his belt;
- Making a Splash: In the form of rain.
- Playing with Fire: Possibly because lightning can start fires.
- Shock and Awe: His powers of thunder and lightning are his most famous.
- Oh My Gods!: Rus nobles swore by him, and even today, many Slavs use varieties of his name as an expletive.
- Top God: The best contender for this position, recorded by Byzantine writer Procopius of Cesarea as the only god of the Slavs, and appearing in pretty much all of Slavdom.
- War God: He's possibly the purest case; his domains tend to be the most martial of the whole pantheon, and warriors of the Rurikids saw him as their patron. But keep in mind that such ostensibly non-martial deities as Yarilo have also been known as war gods.
Thought to be a descendant of PIE snake deity Welnos, and may be likened to Germanic Loki, the Vanir or even Jörmungandr; the Greek Hermes, Hades, and Typhon; and the Vedic Vritra. In the syncretic Dvoyeveriye cults of Old Russia, he was worshipped as Saint Blaise.
- Arcadia: How the underworld, Nav, was depicted. This name occasionally served as an alternate name of Veles.
- Cain and Abel: He and Perun were most likely brothers as well as bitter rivals. However, neither of them was the evil twin, per se; they were just different.
- Composite Character: Some researchers believe that his patronage over cattle came from an unrelated Byzantine saint of accidentally similar name, St. Vlas (Blaise), whose name Veles assumed in the later syncretic cults (dvoyeveriye).
- Elemental Powers
- Dishing Out Dirt: As a good of the earth, it only follows.
- Making a Splash: ... But he was also seen as being associated with water, particularly underground sources of water.
- Everybody Hates Hades: Once averted (the nobles swore by Perun, common folk by him), but then he got Satanified.
- Horned Humanoid: Well... Possibly.
- Our Dragons Are Different: He was often depicted as a snake with the head of a bear and possibly the horns of a cow, which fits the modern conceptions of dragons quite well.
- Plague Master: But he uses plagues to punish the oath-breakers.
- Scaled Up: Sort of, as he was often depicted with dragon and snake-like characteristics.
- Trickster God: The tales don't say much about him tricking people, but he fits into the mold of "mighty warrior god vs. sly trickster god" archetypes.
To solve this conundrum, several theories have been proposed. One of them posits that Svarog is the fire god, and the father to both Svarozic and Dazbog. Another, that there are only two gods, Svarog the sky god, and his son Dazbog the god of fire, Svarozic being an alternate name for one or another.
Svarog himself is mentioned in only one source, where he is the equivalent of Hephaestus. But he is also a contender for the title of the top Slavic god. Dazbog is generally considered a sun god, although according to some, Dazbog had a dual nature as both the diurnal god of the sun and nocturnal protector of the underworld. Svarozic, interestingly enough, is sometimes considered to have been identified with Perun. It seems that regional preferences might have been of matter.
In comparative mythology, analogies are drawn to the proto-Indo-European sky god Dyaeus Pater, a predecessor of figures such as Zeus and Jove; as well as to Hephaestus and other mythical smiths. In the Dvoyeveriye cults, Svarog and Svarogic turned into St.Cosmas and St.Damian (Kuzma i Demyan).
- The Blacksmith: It's usually accepted that he was a god of smithing.
- Genius Cripple: Some of the folk tales depict Svarozic/Dazbog as lame, which draws interesting parallels with all the rest of the lame smithing gods.
- Light 'em Up: Svarog literally means "shining god"/"light god". A massive debate about whereas these are solar, lunar or day deities is fueled by their unambiguous connections with light.
- Lunacy: The moon might have also been Dazbog's area of competence.
- Playing with Fire: Essentially, the whole trio represents different aspects of fire and heat.
- The Power of the Sun: If not for Dazbog, it would have been assumed the Slavs had a female solar deity, as much (ie. comparisons to neighbouring peoples) points to that.
Go figure. A different possibility is that they were day deities (which are not the same as solar deities, and can co-exist with them, such as Dagr and Sól), something implied by Svarog's possible connections to the proto-indo-european Dyeus Phter, the god of the daylit sky.
- Top God: Svarog is a contender for this position. His claim is weaker than Perun's, but he seems to be more popular in fiction.
As some sources compare him to Mars, his patronage of farming might have gone hand in hand with patronage over warring. In comparative mythology, he's also rather similar to Dionysus, particularly the older, chthonic Dionysus of Mycenaean Greece, and the Mesopotamian Dumuzi/Tammuz, who was also a god agriculture and fertility and died for betraying his wife. Post-Christianization, he was equated with Saint George of Lydda and Saint John the Evangelist.
- BrotherSister Incest / Twincest: If the reconstruction is correct, of course.
- Cool Horse: There were temples dedicated to him, where black horses made prophecies by walking over rows of spears.
- Green Thumb: As the god of spring, he personified the growth of plants.
- A Party, Also Known as an Orgy: Seems he wasn't averse to these kinds of festivities in his honour.
In comparative mythology she's close to Hecate, but has also been likened to Ceres.
- Evil Is Deathly Cold: She wasn't really the most beloved deity.
- An Ice Person / Ice Queen: As the goddess of winter, natch.
- Lady of Black Magic: She's very much associated with magic and witchcraft.
- Names to Run Away from Really Fast: The Indo-European particle "mor", which means "death."
- Seasonal Baggage: A case interesting in comparison. As opposed to, say, Greek mythology, where a single goddess's mood brings both summer and winter, in Slavic mythology winter is ruled by a separate deity. Morana's death allows the spring to come.
- Woman Scorned: In aforementioned reconstruction.
- 0% Approval Rating: There is a tradition — notice the present tense — of burning or drowning (or both) her effigy on the first day of spring. In many countries, however, the ancient pagan connection is not well known, and the burned figure is referred to just as "the winter".
- Anthropomorphic Personification: She was worshipped as the soil itself.
- Mother Nature:
- Team Mom: More nurturing than most other earth goddesses. Or, at least, not known to be as nasty.
- I Have Many Names: Also known as Perperuna (pretty much "Mrs. Perun"), and one source's mention of a goddess "Dzidzileyla" might have referred to her.
Pantheon of Kiev
The pantheon of Vladimir of Kiev. Vladimir apparently wanted to codify the pantheon, as a state religion to support his rule, and erected effigies for this purpose. In any case it didn't serve him for long, as it was soon discarded in favour of Christianity. The above mentioned Perun and Dazbog are also members of the pantheon.note- Canon Immigrant: Possibly a Finno-Ugric borrowing, possibly not. Her name might've come from the Slavic word for wet/rain.
- A Date with Rosie Palms: According to folk beliefs, she disapproves. With scissors.
- Marry Them All: In some reconstructions, she's speculated to have been the wife of both Perun and Veles.
- Textile Work Is Feminine: As the goddess of weaving.
- Canon Immigrant/Composite Character: Likely coming from Iranic steppe peoples.
- Lunacy/The Power of the Sun
- Canon Immigrant: May have been imported from the Persians.
- Multiple Head Case: As some scholars think.
- Sealed Evil in a Can: Hard to say if it was so on Vladimir's court, but definitely in the aforementioned story. Details are in the description of Zoryas.
Western Slavs
The Polabiannote Slavs had a multitude of bigger and lesser gods, of which we know comparatively much due to these peoples' constant fighting with the Germans, and with it, consequent interest of German chroniclers (Danish sources occasionally throw in their two cents as well). The Polabian Slavs were unique in Slavdom for the highly organised nature of their cult; they had a priestly class and erected opulent temples. The Lutici, and later, the Rani tribe hosted sanctuaries of trans-regional influence (offerings came from as far as Denmark), whose priests often had the final word in their politics.From what we know, it appears each tribe, or possibly even sub-tribal entities had their own patron, often multi-headed or multi-faced. It's unclear whether they were separate from each other, or local varieties of the same deities, much like the multitude of effigies of Mary in folk Catholicism.
- Canon Immigrant: Possibly, but it's also likely it was a misunderstanding on part of the Christian chroniclers, or even an attempt to fabricate a claim to the island.
- Cool Horse: Another oracular horse, this time white. Svantevith was believed to ride it around the island in the night.
- Iconic Item: His drinking horn.
- Multiple Head Case: Four faces.
- Spell My Name with an "S": His many-faced effigies caused some confusion about his name, although it'll sound the same anyway to a speaker of non-Slavic language. Somewhat confusingly, the outdated version of his name is considered acceptable for the Zbruch idol, as long as it refers to the idol and not the deity.
- Composite Character: His three heads are said to be three other gods, for example Perun, Svarog, and Veles. The first two tend to stay, who the third one is varies.
- Cool Horse: One of his symbols was a black horse.
- Dark Is Not Evil/The Sacred Darkness: Was often represented by a black horse.
- Hijacked by Jesus: Some believe the part about watching over three worlds was not his original attribute, but a mistake or an over-interpretation on the part of Christian chroniclers.
- Multiple Head Case: Three heads.
- Adaptation Expansion:
A minor deity, with a big career in pop-culture, probably thanks to a certain movie.
- God of Evil: Or not. Sources mention that misfortune was attributed to some supernatural force or deity, but this trope would probably be a stretch.
- Hijacked by Jesus: as the Satan equivalent, or even literal Satan-worship.
- Names to Run Away from Really Fast: The Black God.
- Sadly Mythtaken: The depictions of him as Satan.
Others
Minor deities, local, known from limited sources, or hard to pin down.- Love Goddess: Possibly, though they Zoryas may have shared that duty.
- Barrier Maidens: Though it has to be noted, concerning maidenhood, there is no consensus on their marital status.
- The Hecate Sisters: Averted. We mention it here to avoid confusion: the third one is an invention of Neil Gaiman.
- Love Goddess: It's speculated that they were such as a result of comparative mythology, though no surviving myths outright say so.
- Canon Foreigner: As she might not have ever actually been worshipped at all.
- Canon Foreigner: Generally the research doesn't attribute that much importance to him as do some modern worshippers.
