Recently a patron asked:
Where are the science fair project books about dragons?
In ancient times, dragons often represented evil, destruction, and death. In some cases, as in Norse myth, dragons represent greed. They are usually portrayed as frightening and destructive monsters. Gods and heroes must slay them in symbolic battles of good over evil. But a few cultures, notably those of China and Japan, view dragons in a positive light and use them as symbols of good fortune according to the book Mythology, available as an eBook in the Gale Virtual Reference Library.
