Byliny are traditional Russian epic poems that recount the heroic deeds of legendary figures, often called bogatyrs. These poems are typically passed down orally and celebrate themes of bravery, honor, and the struggle between good and evil. They often feature a mix of historical events and mythical elements, reflecting the culture and values of the Russian people. The structure of byliny usually consists of rhythmic verses, making them suitable for recitation. They often include a cast of characters such as Prince Vladimir, Ilya Muromets, and Dobrynya Nikitich, who embody the ideals of strength and loyalty. Byliny play a significant role in Russian folklore and cultural heritage.
