Irish Mythology: FOLK TALES
Ever since the advent of Christianity, on the shores of Ireland, around 460 AD, the pagan elements of Irish mythology had taken the form of folktales. Here, you are going to have Goblins, banshees, leprechauns, fairies,-both malicious and good and definitely not the little winged creatures may so popular by Victorian artists. You also have that, water horse which lives in lakes and has a back broad enough to carry six children. Any scientific research researcher can consider this water horse, a remnant of a supposedly extinct dinosaur species, because after all, Ireland has been around for 1.9 billion years. And actually it is going to be carnivorous because it has sharp teeth.
If one takes the supposedly imaginary stories of mythology and looks at them in a sensible manner, there is always a genuine and scientific explanation, which takes out all the excitement and the romance out of mythological stories.
For example, any flying Dragon or Roc is nothing but a surviving Pterodactyl. In the same manner, the Minotaur of Crete was definitely a surviving meat-eating dinosaur. Nevertheless, Irish mythology is full of bogles, Kobolds, leprechauns, pixies, fairies, which naturally are either mutated beings or creatures of another Homo species, which went off in another direction in their revolution, and stayed tiny.
That is the reason why they have complete human instincts like wanting to eat everything a human eats etc. That is the reason why they accepted the food left out for them by the good wives of the village. As they came out only at night, the aura of myth and magic surrounding them grew proportionately. There is a possibility that they encouraged this to make human beings, serve them. That is the imaginary story of the origin of folktales in Irish mythology!
