The Myth
Bies is an evil spirit or demon in Slavic mythology. The word bies is associated with an evil supernatural being and, following the Christianization of Slavic peoples, became closely identified with the Devil and with the demon known as Chort or Czort.
In Christian-influenced tradition, Bies came to represent the Devil or other demonic beings. The plural biesy was used in Russian translations of the New Testament for the devils that possessed the swine in the Gospel of Mark. Related Slavic words also developed meanings associated with madness and uncontrolled behavior. In Slovenian, Croatian, and Serbian, the related forms bes and bijes mean “rage” or “fury.”
A separate being called bès is found among the Jah Hut people of Malaysia. These bès are dangerous spirits inhabiting the jungle. They can attack people and cause illness through spirit possession.
The Jah Hut can attempt to tame and contain a bès by carving a small wooden figure called a sepili, representing the particular spirit causing trouble. If the spirit approves of the figure, it may enter it, allowing the people to trap the spirit inside through a special ritual. The sepili must then be taken far away from the village because the bès may become angry when it eventually escapes. Traditionally, the figures were buried deep in the jungle.
