Jack Frost embodies the essence of frost, ice, snow, sleet, winter, and bone-chilling cold. Originating as a variation of Old Man Winter, Jack is attributed to frosty weather, nipping fingers and toes in the cold, painting autumn foliage, and etching fern-like patterns on windows during winter. In literature from the late 19th century onward, Jack Frost evolved into a more complex character. Depictions of him range from a sprite-like figure to a mischievous troublemaker or even a heroic persona.
