This Lithuanian sakmė, or etiological folk tale, offers a mythological explanation for lightning strikes, demonstrating how pre-scientific cultures interpreted natural phenomena through narrative frameworks that reinforced moral and social values.

According to the tale, the origin of lightning can be traced to an ancient conflict between Perkūnas, the powerful thunder god in Baltic mythology, and the devil. The narrative begins with the devil borrowing money from Perkūnas but then refusing repayment and mocking the god, triggering Perkūnas' rage. This initial transgression—breaking a promise and disrespecting a divinity—establishes the moral foundation of the story.

The lightning that flashes across the sky represents Perkūnas' continuing pursuit of the devil, who attempts to hide in various places: on farms, inside animals, or within people's clothing. When lightning strikes a tree, sets fire to a house, or kills a person or animal, it is explained as the devil hiding there, making these locations the inadvertent targets of Perkūnas' wrath.

This narrative demonstrates how mythological explanations often served multiple functions in traditional societies. Beyond explaining the natural phenomenon of lightning, the tale reinforces social values regarding debt repayment and respect for authority. It also provides practical guidance by warning people about potentially dangerous locations during thunderstorms.

The story's structure, with the devil constantly fleeing and Perkūnas relentlessly pursuing, creates a compelling explanation for lightning's unpredictable and repeated nature. This cyclical, unresolved conflict explains why lightning continues to occur rather than being a one-time event.

Compiled and edited by folklorist Norbertas Vėlius in How the Earth Came to Be: Lithuanian Etiological Legends, this tale exemplifies how mythology provided frameworks for understanding natural phenomena while reinforcing cultural values and practical knowledge.
