Nearly every country around the world has it's own legends about Dragons, for example:
HYDRA - Origin: Norse/Greek Myth
SAINT GEORGE - Origin: English History
SIGURD & THE DRAGON FAFNIR - Origin: Norse Myth
JORMUNGAND, THE MIDGARD SERPENT - Origin: Norse Myth/Scandinavia
THE LAMBTON WORM - Origin: English History
NIDHOGG / NIDDHOGG / NYDHOGG - Origin: Scandinavian/Germanic Mythology
THE PIASA - Origin: North America
THE ETHIOPIAN DREAM - Origin: Ethiopia
BEOWULF & THE DRAGON - Origin: Anglo-Saxon
The only two dragons out of the list I know something about are the first two, the others are a bit obscure. Does anyone else know anything about Dragons as it is an interesting subject.
