It is said that on medieval maps, cartographers drew pictures of dragons, with the legend hic sunt dracones ('here be dragons' in Latin) in unknown territories where they thought that what was actually there might be dangerous.

Dragons have been part of mythology for thousands of years, in tales from all around the world. The oldest stories dates from the ancient Near East about 4000 years ago. No-one really knows where the idea of dragons came from - it might be because of people's fear of snakes, or because they found dinosaur bones that they didn't understand.

What do you think? Did dragons really exist?
