Idolishche — Russian fairy tale character

Idolishche Poganoye is a mythological monstrosity from Russian bylinas (epic tales) and other folklore; he personifies pagan forces invading the Russian lands. The name literally means "pagan idol", with a Russian augmentative suffix "-ishche".

The major epic sources that involve Idolische are various variants of the bylina "Ilya Muromets and Idolishche Poganoye", which may also characterise Idolishche as "Tatarin" (the Tatar), in reference to the Tatar-Mongol yoke.
