Jack Frost is a figure from folklore, an elfish creature who personifies crisp, cold weather. He is said to leave those beautiful patterns on autumn leaves and windows on frosty mornings. It is thought that he originated in Norse folklore as Jokul ("icicle") or Frosti ("frost"). In Russia, frost is represented as Father Frost, a smith who binds water and earth together with heavy chains. In Germany however, it is an old women who causes it to snow by shaking out her bed of white feathers.
