The pictures of monsters below come from four different traditions. The first picture is entitled The Sea Monster, by Albrecht Durer. It is an engraving from around 1498.

The secound picture is The Head of the Medusa by Pieter Pauwel Rubens, from 1617. It shows the severed head of the mythological monster.

The third picture is from a Japanese movie. From a mere film, Godzilla, King of the Monsters has become a major export product of Japan.

The fourth picture is a different approach to monsters. It is the DVD cover of Pixar's Monsters, Inc.
