Y Ddraig Goch (Welsh Dragon). The Romans used the dragon as one of their symbols of power. Into battle they would carry a metal head of a dragon in which they would light a fire. This would burn fiercely in the wind and seems to be where all the legends of fire breathing dragons come from. When the Romans left Britain it seems that the dragon was adopted by others as their symbol of power. Hence the Welsh Dragon of today.
Formidable predators, dragons(also known as wyrms and drakes) are massive in size with fearsome teeth, deadly breath, vicious claws, and hides like stone. Dragons generally make their home in caves and mountains, far from humankind, but when they come close to people, their huge appetite is generally a source of conflict.
