Perun
In Slavic mythology, Perun is the highest god of the pantheon and the god of sky, thunder, lightning, storms, rain, law, war, fertility and oak trees. His other attributes were fire, mountains, wind, iris, eagle, firmament, horses and carts, weapons, and war. He was first associated with weapons made of stone and later with those of metal.
Etymology
Perun is strongly correlated with the near-identical Perkūnas/Pērkons from Baltic mythology, suggesting either a common derivative of the Proto-Indo European thunder god, or that one of these cultures borrowed the deity from the other. The root *perkwu originally probably meant oak, but in Proto-Slavic this evolved into per- meaning "to strike, to slay".The Lithuanian word "Perkūnas" has two meanings: "thunder" and the name of the god of thunder and lightning.
Artifacts, traditions and toponyms show the presence of the cult of Perun among all Slavic, Baltic and Ugro-Finnic peoples. Perun was also related to an archaic form of astronomy – the Pole star was called Perun's eye and countless Slavic and Hungarian astronomers continued this tradition – most known ones are Nicolaus Copernicus, and Franz Xaver von Zach.
Myth
In Slavic mythology, much like in Norse and Baltic mythologies, the world was represented by a sacred tree, usually an oak, whose branches and trunk represented the living world of heavens and mortals, whilst its roots represented the underworld, i.e. the realm of the dead. Perun was the ruler of the living world, sky and earth, and was often symbolised by an eagle sitting on the top of the tallest branch of the sacred tree, from which he kept watch over the entire world. Deep down in the roots of the tree was the place of his opponent, symbolised by a serpent or a dragon: this was Veles, watery god of the underworld, who continually provoked Perun by creeping up from the wet below up into the high and dry domain of Perun, stealing his cattle, children, or wife. Perun pursued Veles around the earth, attacking him with his lightning bolts from the sky. Veles fled from him by transforming himself into various animals, or hiding behind trees, houses, or people; wherever a lightning bolt struck, it was believed that this was because Veles hid from Perun under or behind that particular place. In the end, Perun managed to kill Veles, or to chase him back down into his watery underworld. The supreme god thus reestablished order in the world, which had been disrupted by his chaotic enemy. He then returned to the top of the World tree and proudly informed his opponent down in the roots "Well, there is your place, remain there!". This line came from a Belarusian folk tale. To the Slavs, the mythological symbolism of a supreme heavenly god who battles with his underworldly enemy through storms and thunder was extremely significant.While the exact pantheon characterization differed between the various Slavic tribes, Perun is generally believed to have been considered as the supreme god by the majority, or perhaps by nearly all Slavs, at least towards the end of Slavic paganism. The earliest supreme god was probably Rod; it is unclear precisely how and why his worship as the head of the pantheon evolved into the worship of Perun. Another candidate for supreme deity among at least some Slavs is Svarog.
Weapons
In the classification scheme of Georges Dumézil, Perun was the god of the second function, a god of war, and as such, he was armed with several fantastic weapons. Perun's lightning bolts were believed to be stones and stone arrows. According to folk beliefs, fulgurites, belemnites, and sometimes even the remains of prehistoric stone tools found in the ground are remains of these weapons. Various Slavic countries also call these deposits "Perun's stones", "thunderbolt stones", "thunderbolt wedges" and "Perun's arrow"; other unrelated names for these include "devil's finger", "God's finger", and "Mother of God finger", and in Lithuania, "Perkun's finger". These thunderbolt stones were sometimes said to be transferred back to the sky by the wind after being under earth for a period of seven years. The weapons of Perun protected against bad luck, evil magic, disease, and – naturally enough – lightning itself.Perun also had another type of weapon in his arsenal, as destructive as his firestone arrows, but even more unusual: mythical golden apples. While this may not seem to be much of a weapon, in many Slavic folk accounts, the golden apple appears as a talisman of ultimate destruction. An example from a Serbian folk song from Montenegro with strong mythical elements relates:
…Те извади три јабуке златне
И баци их небу у висине...
…Три муње од неба пукоше
Једна гађа два дјевера млада,
Друга гађа пашу на дорину,
Трећа гађа свата шест стотина,
Не утече ока за свједока,
Ни да каже, како погибоше.
"…He grabbed three golden apples
And threw them high into the sky...
…Three lightning bolts burst from the sky,
The first struck at two young grooms,
The second struck pasha on brown horse,
The third struck six hundred wedding guests,
Not an eyewitness left
Not even to say how they died."
It is conjectured that the mythical golden apples of Perun were symbols of a rare but notorious form of atmospheric discharge, ball lightning. The same is probably true for the thunder marks of East Slavic folklore, of which two examples are shown above.
Characteristics
Remains of an ancient shrine to Perun discovered in Peryn consisted of a wide circular platform centred around a statue, encircled by a trench with eight apses, which contained sacrificial altars and possibly additional statues. The overall plan of the shrine shows clear symbolism of the number nine. This is sometimes interpreted that Perun, in fact, had nine sons. In some Slavic folk songs, nine unnamed brothers are mentioned.Similarly to Perkūnas of Baltic mythology, Perun was considered to have multiple aspects. In one Lithuanian song, it is said there are in fact nine versions of Perkūnas. From comparison to the Baltic mythology, and also from additional sources in Slavic folklore, it can also be shown that Perun was married to the Sun. He, however, shared his wife with his enemy Veles, as each night the Sun was thought of as diving behind the horizon and into the underworld, the realm of the dead over which Veles ruled.
Like many other Indo-European thunder gods, Perun's vegetative hypostasis was the oak, especially a particularly distinctive or prominent one. In Southern Slavic traditions, marked oaks stood on country borders; communities at these positions were visited during village holidays in the late spring and during the summer. Shrines of Perun were located either on top of mountains or hills, or in sacred groves underneath ancient oaks. These were general places of worship and sacrifices.
In addition to the tree association, Perun had a day association as well as the material association.
