The Lifecycle Growth And Evolution Of Gods/religion In Tandem With the (perhaps) Collective Unconscious Understanding Of General Mythos - Blog Posts
Thank you for the question @newbiepagancat ! I’ll give you a direct answer and a broader view answer.
Direct answer: The general theme of the myth was reconstructed by slavists on the basis of folk songs, folktales and comparative mythology, there is no one concrete historical source. The names of gods and the storyline connecting multiple myths are an educated speculation by slavists of yore. The minute details are typically added by neopagans as they’re almost impossible to reconstruct.
The Russian philologists Ivanov and Toporov found (mainly on the tradition about Zeleni Jurij) traces of the principal myth of Perun and Veles, linking Jurij/Jarylo with the Balto-Slavic Jarovit, a deity of fertility, who was initially worshipped on April 15. Furthermore, Radoslav Katičić wrote extensively on Jurij’s myth among the Slavs and on the duel between the Thunder God with a dragon. Both Radoslav Katičić and Vitomir Belaj share the opinion that Jurij/Jarylo is the son of Perun and thus central to the pre-Slavic vegetation and fertility myth. Jurij was taken by envoys of Veles to the land of the dead from which he returned to the world of the living in spring. As a harbinger of spring, Zeleni Jurij is also connected with the circular flow of time and with renewal. According to Katičić’s reconstruction of the myth of Zeleni Jurij, the mythic story recounts how young Jurij rides his horse from afar, from the land of eternal spring and the land of the dead – from Veles’ land – across a blood-stained sea, through a mountain to a green field. (…) At the end of his journey, Jurij arrives at the door of Perun’s court to marry Perun’s daughter, (his own sister) Mara. Together with the sacrifice of the horse, the hieros gamos ensures the growth and fertility of plants. Some Slovene folktales and songs also mention an incestuous relationship between a brother and a sister, which is the reminiscence of the sacred marriage already mentioned in the myth of Kresnik. The sacred marriage is therefore also connected with Zeleni Jurij.

Mikhailov summarized Ivanov’s and Toporov’s reconstruction of the basic myth by describing that the thunder god Perun, who dwells in the sky on the top of a mountain, persecutes his enemy, who has the form of a snake and lives below on earth. The reason for their conflict is that Veles stole cattle and people, as well as the Thunderer’s wife in some versions of the story.

Broader worldview answer: There are some common mythological themes that exist in one form or another among countless different cultures and peoples, adjusted to fit the local gods and their broader stories.
The God of Thunder fights The Serpent of the Waters. They have to fight - be it as Perun and Veles, as Thor and Jörmungandr, as Zeus and Typhon or as Marduk and Tiamat. The detailed reasons will vary but will make sense locally. The older and simpler reason is likely that we need a good justification for the changing of the seasons.
The Death will always take away someone’s Loved One, sometimes that Loved One will be a child, since that makes coping with the situation particularly difficult. That’s just what death does - be it as Veles and Yarilo or as Hades and Persephone. Bonus points for explaining the seasons changing too.
So let’s say you’re a slavist or a neopagan desperate for a coherent body of Slavic myths but lacking one. All you have to work with are some fleshless skeletons of myths, painstakingly glued together from random bones that you found here and there. Truth be told you only managed to get this far because they’re real classics of the genre and other cultures tend to have similar ones too. Let’s introduce the skeleton gallery in play here:
The Thunderer and the Serpent are fighting (described more in depth here),
The God of Death/Underworld abducts a child (described in the quotes above),
The Spirit of Vegetation has to die - creative sacrifice/murder (explained shortly here),
The Fire and Water need to marry at Midsummer - magical incest temporarily allowed (explained in this post, if it’s too long just read the last quote and the tldr).
(You might notice pretty much all those myths are centered around vegetation, what makes plants grow, and people needing to have food. Two first skeletons do a decent job of explaining change of seasons and the reason for seasonal coming of rains, that are needed for the fields to grow; two last ones are related to rituals that are supposed to ensure that land stays fertile/there’s enough sun and water so that grain grows and we can avoid starving.)
Ok, so let’s say you’re a slavist or a neopagan desperate for a coherent body of Slavic myths. What is the optimal way to connect the dots here?
Perun and Veles fight. Why are they fighting? Multiple reasons but the biggest one is Veles stealing something that rightfully belonged to Perun. What did he steal? Well the myth works perfectly if it’s a) a child and b) a spirit of vegetation. This fits both Morana and Yarilo and I saw fans of both versions, but let’s go with Yarilo here. Because of a flower, a folk song and an old chronicle Yarilo/Yarovit, the spirit believed to be one of vegetation, life, spring, sun etc. has to marry the spirit of vegetation, water and death, that miiiiiight also be his sister. How the fuck do you marry your own sister? Well you got abducted and separated at young age, but as The Spring, The Embodiment of Sprouting Seeds and maybe also The Sun Child, Yarilo (born at Midwinter) will come out from the Underworld uscathed as a young adult and meet a girl who he fails to recognize as his sister and marries at Midsummer (part of fertility ritual for good harvest). Anyway tragedy follows, could be murder, could be suicide, either way it has to be death.
Why? Because that’s what makes sense, the most optimal way to put together the puzzle pieces that we currently have. Does that mean that’s exactly what Ancient Slavs believed? No, but a) we don’t know for sure what they believed and will likely never find out for sure, b) they probably believed bunch of different, conflicting stories depending on the region.
Obviosuly speculating slavists are much more light-handed than speculating neopagans. The slavists will usually let you know which parts they added, why they hold this particular belief, what purpose this story may serve, what other authorities support their hypothesis, and of course, that nothing is for sure and this is merely a hypothesis. Neopagans are rarely this kind and forthcoming.
Have a lovely day!
