The exact history of snowman making could never be traced, as it finds no particular mention in books or texts.
Some speculated that since snow used to be the most flexible and inexpensive form of artistic medium, snowman making gradually became a cross-cultural phenomenon; others believed that Snowmen were originally crafted by Santa to assist with his mission of delivering presents around the world.
The theory of Snowmen being Santa's courier aligned with some of the oldest documentation dating back almost 2 thousand years ago, that they seemed to suddenly populate cities around the world at Christmas Eve, and disappear before dawn of Christmas day.
Whether Snowman secretly delivers presents down the chimney still has yet to be proven, but there is no doubt that Snowman is and will continue to be a monumental cross-cultural symbol of having fun during the snowy seasons.
