One of the most important figures constantly brought up during the Christmas season is Saint Nicholas, despite the fact most people know little about him. In the 21st century, Saint Nicholas (or as people often refer to him, “Jolly Old Saint Nick”) has been reduced to a pretend, adorably portly grandfather-type, a visual often accompanied by a fleet of magical reindeer and a bustling workshop staffed by endlessly cheerful elves. Most assume, quite understandably, that Saint Nicholas was the fount of inspiration that Santa Claus' myth weavers steadily drank from over the centuries. While this is accurate to some extent, it is important to remember that the parallels between Saint Nicholas and the present-day Santa Claus marketed by mass media are actually quite limited.

After Nicholas of Myra’s death, December 6 became his feast day, and over the centuries, children anticipated his appearance with gifts. However, other children, particularly those of the mischievous sort, trembled under their covers on December 6, because they could not look forward to tinkling sleigh bells or belly-shaking laughs. Instead, they feared the disconcerting sounds of heavy breathing, guttural growls, and rattling chains, all of which came from the terrifying Krampus.

Despite the best efforts of the Catholic Church and other conservative groups, Krampus is in the midst of a major Renaissance, penetrating not only modern literature, but even becoming a fixture of pop culture. This is evidenced by the creature's recent starring roles in the films Krampus, Night of the Krampus, and Mother Krampus, and its cameos in such TV shows and animations as Grimm, Supernatural, American Dad, and Venture Brothers.
