 Some of the Pre-Christian Dutch mythology took less sacred forms in the Middle Ages folklore and fairy tales, for example, tales of the witte wieven, elf and kabouter continued, combining Christian and fairy tale elements.The mythology of Wodan on the Wild Hunt sailing through the sky, is thought to have been one of the tales that changed into tales of Christian Sinterklaas traveling the sky.Dutch folk tales from the Middle Ages are strong on tales about flooded cities and the sea.
