El mundo de los dragones

Everybody knows what a dragon is: an enormous, fierce creature appearing in fairy tales and legends as an accessory whose main function is to set off the bravery of the knight challenging him. The dragon is a mysterious character.
Dragons are legendary beasts in the folklore of many European and Asian cultures. Legends describe dragons as large, lizardlike creatures that breathe fire and have a long, scaly tail. In Europe, dragons are traditionally portrayed as ferocious beasts that represent the evils fought by human beings. But in Asia, especially in China and Japan, the animals are generally considered friendly creatures that ensure good luck and wealth.
According to some medieval legends, dragons lived in wild, remote regions of the world. The dragons guarded treasures in their dens, and a person who killed one supposedly gained its wealth. The English epic hero Beowulf died in a fight with a treasure-guarding dragon.
In China, the traditional New Year's Day parade includes a group of people who wind through the street wearing a large dragon costume. The dragon's image, according to an ancient Chinese belief, prevents evil spirits from spoiling the new year. Another traditional Chinese belief is that certain dragons have the power to control the rainfall needed for each year's harvest.
