Who is Jack Frost?
Jack Frost is a personification of frost, ice, snow, sleet, winter, and freezing cold. He is a variant of Old Man Winter who is held responsible for frosty weather, nipping the fingers and toes in such weather, coloring the foliage in autumn, and leaving fern-like patterns on cold windows in winter. Starting in late 19th century literature, more developed characterizations of Jack Frost depict him as a sprite-like character, sometimes appearing as a sinister mischief-maker or as a hero.
