This appears to be the case in the book of Job, where a crocodile type beast is described in detail. Yet, some historians believe these stories may have also been influenced by the discovery of dinosaur fossils or tales of creatures such as the crocodile. The dragons mentioned are usually taken by modern readers as symbols of evil, such as the dragon in the book of Revelation. Dragons are everywhere in Christian art and literature, especially in the lives of the saints, where these holy men and women are portrayed as triumphant victors over inherently evil creatures.
