Long before Santa Claus became a symbol of joy, many cultures believed Christmas was a time when dark creatures roamed the night—punishing the wicked and rewarding the good. These scary christmas creatures from mythology and dark christmas legends have haunted winter celebrations for centuries, from the infamous Krampus to Iceland's child-eating giantess Grýla.

Christmas Mythology Creatures: Dark Legends of the Winter Season

The best way to make children behave properly would be to remind them about Santa Claus and Christmas. After all, only the good ones get the presents right? If they still wouldn't listen, here is a list of mythical creatures visiting this Christmas to change their mind. And not all of them plan on giving gifts.

Olentzero

Olentzero

Let us start this list with a nice guy. Olentzero is a character from the Basque Country legend. He is the equivalent of Santa Claus. The word Olentzero literally means "time of the good ones." It is said that on the night of the 24th of December, Olentzero visits the houses of the people to drop off presents for children. Legend has it that Olentzero was one of the Jentillak, a mythological race of Basque giants.

One day there was a very bright cloud in the sky, and no one could see it except Olentzero, who was very old and nearly blind. He confirmed that to be the sign of the birth of Jesus Christ, so he asked the giants to throw him off the cliff to avoid Christianisation. However, the giants tripped and fell, and Olentzero was the only one left alive and embraced Christianity.

Mari Lwyd

The Mari Lwyd is a folk tale from South Wales. According to tradition, the Mari Lwyd consists of a horse's skull mounted on a pole carried by an individual hidden under a sackcloth. This custom is observed to mark the passing of the darkest days of winter. This is the reason why it overlaps with the celebration of Christmas.

The Mari Lwyd party usually consists of four to seven men with colored ribbons attached to their dress. The party would approach a house singing a song to request entry. The inhabitants of the house would then give some excuse as to why they couldn't enter, which would be followed by another song until they ran out of excuses.

Once inside the Mari Lwyd would then cause havoc and scare the children while the party would try to restrain it.

Befana

Befana

Befana is part of Italian folklore. She is an old woman who delivers gifts to children on Epiphany Eve, which is on January 5th. Befana is portrayed as a hag riding a broomstick wearing a black shawl. She visits each house and leaves candy and fruits for good children while leaving coal, onions or garlic for the bad ones.

According to Christian legend, Befana was approached by the three biblical magi who were in search of Jesus. She did not know where he was, but provided them shelter for the night. However, she refused their offer to join them in their search for Jesus.

She later had a change of heart and searched for baby Jesus but never found him. She continues to search for him and leaves gifts for children who are well behaved.

Perchta

Perchta: The Belly-Slitting Christmas Demon

Perchta, also known as Berchta, was once a pagan goddess. Her name means "the bright one." She may appear in the form of a beautiful woman who is as white as snow or an old hag with tattered and torn clothes. She also has one large foot which signifies that she can shapeshift into any animal. Perchta is the upholder of cultural taboos and one of the most terrifying christmas mythology creatures.

During the time between Christmas and Epiphany, she roams the countryside to enter homes. If the children are well behaved, she leaves a small silver coin in a shoe. Seems good, right? No. This dark christmas legend takes a gruesome turn: if children had not behaved properly that year, she would slit their bellies, remove their stomach and guts, then stuff them with straw and pebbles! This naughty children folklore tale should be enough motivation to be good.

Grýla

Grýla: Iceland Folklore's Child-Eating Christmas Demon

She has the ability to detect children who misbehaved all year. During Christmas, she descends from the mountains to nearby towns in search of her "meal." This naughty children folklore creature's favorite snack is, disturbingly, children themselves. She leaves her cave specifically to hunt for misbehaving kids, and according to Icelandic tales, there is never a shortage of food for her.

Her favorite dish? A stew made of naughty children—a terrifying centerpiece of this dark christmas legend.

This threat of being eaten by the cat was used by farmers as an incentive for their workers to finish processing the wool before Christmas.

We have all heard about werewolves. A werewolf is a legendary human with the ability to shapeshift into a wolf. Werewolves are also woven into dark christmas legends in surprising ways. It is widely believed that as the hour of Christmas drew near, the forces of evil also raged more fiercely. In Prussia, Livonia, and Lithuania, these scary christmas creatures are believed to gather around Christmas to attack human settlements.

In Latvia and Estonia, it is believed that a Christmas boy lame of legs goes around recruiting demon followers. Those who join reluctantly are then turned into werewolves using an iron whip.

In Poland and northeastern Europe, if a child is born on Christmas day, then he is more likely to become a werewolf. This is because it is said to be audacious to have the same birthday as Jesus Christ.
