Draco

The Latin word for a dragon, draco (genitive: draconis), actually means snake or serpent, emphasizing the European association of dragons with snakes, not lizards or dinosaurs as they are commonly associated with today.

In medieval symbolism, dragons were often symbolic of apostasy and treachery, but also of anger and envy, and eventually symbolized great calamity. Several heads were symbolic of decadence and oppression, and also of heresy. They also served as symbols for independence, leadership and strength. Many dragons also represent wisdom; slaying a dragon not only gave access to its treasure hoard, but meant the hero had bested the most cunning of all creatures. In some cultures, especially Chinese, or around the Himalayas, dragons are considered to represent good luck and fortune.
