The name "dragon" comes to us from the Greek word for seeing "derkein". The dragon is supposed to have unusually sharp vision in the physical, intellectual and psychic realms. In legends, it is known as a prophet; a riddler; and a guardian of temples, paradises, magic, and hidden treasures.
Siegfried battled a dragon for immortality and Hercules confronted one for the golden apples of great happiness. Sometimes the key to the entrance of these hidden places is the hero’s own sword, dripping with the dragon’s blood.
From these legends, the dragon gains a reputation for strength, vigilance, wisdom, jealousy, and miserliness.Vikings had dragon figureheads on the prow of their ships. The dragons on the ships were believed to endow keen site and cunning to the Viking warriors.
In both Eastern and Western cultures, the dragon is the symbol of things, attitudes, or habits which although difficult to resist must be overthrown. The Japanese Buddhist, Fudo-Myoo overthrew blindness and ignorance symbolized by the dragon.
