[Ciaphas Cain]

Dragons, along with ghosts, are an almost universal legend throughout the cultures of human history. Wherever men have lived, there have been tales of dragons.

One might wonder why that is.

Folk tale-wise, I think dragons are a way too make snakes scarier.

Are there cultures with no snakes that also lack dragon lore? Aleuts maybe? Saamis?
