He is said to leave frosty crystal patterns on windows on cold mornings. Those who believe in Viking folklore roots state that the English derived the name Jack Frost from the Norse character names, Jokul ("icicle") and Frosti ("frost"). Another theory is that he is a much more recent import into Anglo-Saxon culture from a Russian fairy tale. In the Finnish eposKalevala Canto number 30, translated from Finnish into English by Keith Bosley, Jack Frost is the son of Blast, "Pakkanen Puhurin Poika" (see Finnish Kalevala). Other tales in Russia represent frost as Father Frost, a smith who binds water and earth together with heavy chains. In Germany however, it is an old woman who causes it to snow by shaking white feathers out of her bed.
