The Wawel Dragon

The Wawel dragon or Wawel tzmok (in Polish, "smok wawelski", aka całożerca, aka holophagus - that is, a creature that swallows its victims whole, a zhivoglot) is a creature from Polish folklore that lives in a cave (called Dragon pit) at the foot Wawel Hill in Krakow.

Once a week, a cow was to be sacrificed to the dragon; if he did not receive it, he devoured people in return. On numerous monuments, he is depicted as a huge lizard-like creature with wings, spewing fire.
