The Myth
Lyadashtsik is an evil spirit from Belarusian folklore that is said to corrupt people. It is regarded as one of the most hostile spirits toward humans and is especially feared by women, as many illnesses and seizures affecting women were traditionally attributed to it.
The spirit was believed to attack by making people sick, driving them into madness, or causing them to transform into various animals. Those believed to have been afflicted by Lyadashtsik were sometimes described as foolish or half-witted.
Lyadashtsik was imagined as a hideous monster covered in red hair. It possessed wings, a single eye in the middle of its forehead, and was said to resemble a monstrous bat. In some traditions it was also described with the body of a frog and hairy wings.
The creature was known under different names in various parts of Belarus. In some districts it was called Shevredz, while in others it was known as Pusten. Folk sayings warned that a person who had dealings with Lyadashtsik had “Lyadashtsik’s eye,” meaning they had become mad or half-witted.
