When one thinks of modern Christmas, warm images from Christโs nativity to Santaโs midnight sleigh ride might come to mind. However, Saint Nicholas is not the only thing that goes bump in the nightโYule monsters represent another syncretized and modernized phenomenon, which corresponds to a medieval tradition that presents winter solstice as an ideal setting for monsters to emerge from the darkness of the long night. In celebration of the holiday season, my latest blog in our series on monsters will consider the tradition of Yuletide monsters and discuss some instances of Christmas haunting in vernacular Middle English and Old Norse-Icelandic sources, thereby catching a brief glimpse at a broader medieval tradition of monsters associated with the winter solstice.

Christmas hauntings have a deep cultural and literary history. One seasonal spook, the Slavic Baba Yagaโa present-stealing witchโis generally remembered today as a holiday monster, though her character has only become associated with Christmas and New Years in modern times. Another, perhaps the most famous Yule monster, is Krampusโthe notorious, child-stealing Christmas demon and son of Hel (the Norse goddess of the underworld), who is still popular in modern Germany and increasingly abroad. These modern Christmas hauntings align with a robust medieval tradition of Yuletide monsters that come with the cold and specifically the long night of the winter solstice. Even Grendel in Beowulf, who notoriously terrorizes the hall of Heorot, does so for XII wintra tid โtwelve wintersโ timeโ (147) specifically. While this phrase surely refers to the monsterโs yearlong assault on Denmark, it also seems to stress the dark and snowy season as the prime time for Grendel’s hauntings.

Today, I will mention three popular medieval textsโone poem and two sagasโwhich feature Christmas hauntings of all types, including by a green man, an undead revenant, a troll woman and a dragon.
Although most of the Christmas monsters discussed in this blog come from popular Old Norse-Icelandic sagas, the Middle English alliterative poem Sir Gawain and the Green Knight begins with a mysterious Green Knight, gome gered in grene โa man geared in greenโ (179), described as half etayn in erde โhalf-giant on earthโ (140) and aluisch mon โelvish manโ (681), who appears at Camelot on Christmas riding a green horse and wielding a green axe. Not only does the Green Knight come at Yule (284), he emerges in court wearing a fur-trimmed robe (152-56) and holding a holyn bobbe โholly bundleโ (206) in his hand, as if he were the Ghost of Christmas Present from Charles Dickens’ A Christmas Carol.

Moreover, he explicitly wishes to play a Crystemas gomen โChristmas gameโ (283). The passage describing the Green Knightโs arrival emphasizes his coming for the Christmas festivities, thereby linking him with the tradition of Yuletide monsters. The Green Knight declares that since there is no warrior who can match him in battle:
I craue in รพis court a Crystemas gomen,
For hit is ศol and Nwe ศer, and here ar ศep mony:
If any so hardy in รพis hous holdez hymseluen,
Be so bolde in his blod, brayn in hys hede,
รat dar stifly strike a strok for an oรพer,
I schal gif hym of my gyft รพys giserne ryche,
รis ax, รพat is heuรฉ innogh, to hondele as hym lykes,
And I schal bide รพe fyrst bur as bare as I sitte (283-290).
โI desire in this court a Christmas game, for it is Yule and New Year, and you here are many. If any in this house holds himself so hardy, be his blood so boldโhis brain in his headโthat he dare stiffly strike one stroke for another, I shall give him my gift, this rich gisarmeโthis axeโthat is heavy enough to handle as he likes, and I shall abide the first blow, as bare as I sit.โ

Christmas stays a prominent theme throughout the poem, and it operates as a metric by which to measure time. Gawain spends the following Christmas with Lord and Lady Bertilak in anticipation of the subsequent Christmas game, when the Green Knight will deliver a return blow. Christmas feasting both begins and concludes this Middle English romance, enveloping the narrative with this holiday theme. Indeed, Christmas is mentioned nine times in the poem, demonstrating its role in framing the narrative. Yule is mentioned twice, and the first reference comes from the Green Knight himself as to the reason for his journey to King Arthurโs court.
The next text in our discussion is the Old Norse-Icelandic Grettis saga, which contains multiple Christmas haunting episodes, each featuring a very different type of Yule monster. In Grettis saga, the holiday of Yule is likewise a repeated fixture and marker of time, and Yule is referenced thirty-three times in the saga.

The major and most frequently discussed Yuletide haunting in the saga concerns the undead revenant Glรกmr, a Swedish herdsman who ignores Christmas traditions:
Nรบ leiรฐ svo รพar til er kemr aรฐfangadagr jรณla. รรก stรณรฐ Glรกmr snemma upp ok kallaรฐi til matar sรญns. Hรบsfreyja svaraรฐi: “Ekki er รพaรฐ hรกttr kristinna manna at matast รพenna dag รพvรญ at รก morgun er jรณladagr hinn fyrsti,” segir hรบn, “ok er รพvรญ fyrst skylt at fasta รญ dag” (chapter 32).
“Now time past there until when comes the eve of Yule. Then Glรกmr stood up and called for his food. The lady of the house answered: โIt is not proper that Christian men eat meat on this day, because tomorrow is the first day of Yule,” she says, “and thus they shall first fast today.โโ
Glรกmr’s response marks him as explicitly unchristian, which may serve to foreshadow his untimely demise:
Hann svarar: “Marga hindurvitni hafiรฐ รพรฉr รพรก er ek sรฉ til einskis koma. Veit ek eigi at mรถnnum fari nรบ betr at heldr en รพรก er menn fรณru ekki meรฐ slรญkt. รรณtti mรฉr รพรก betri siรฐr er menn voru heiรฐnir kallaรฐir ok vil ek mat minn en รถngvar refjar” (32).
โHe answers, โYou have many restrictions, when I see no good come of it. I do not know that men fare better now than when they did not heed such things. It seems to me that the customs of men were better when they were called heathens, and now I want my meat, and no foolishness.”

After his praise for heathenism, spurring caution, Glรกmr ventures into a known haunted region at Yuletide, and he never returns. We are told that kom hann ekki heim jรณlanรณttina โhe came not home on Yule-nightโ and soon we learn that he has died. After days of searching and a number of attempts to bring Glรกmrโs body to the church to be buried, eventually the townsfolk give up and bury Glรกmr where they find him, and รaรฐ drรณgu menn saman at sรบ meinvรฆttr er รกรฐr hafรฐi รพar veriรฐ mundi hafa deytt Glรกm โmen drew from this, that the evil spirit which had been there before will have killed Glรกmr.โ However, shortly thereafter, it is the undead Glรกmr who perpetrates Yuletide hauntings, as the saga reports:
Litlu sรญรฐar urรฐu menn varir viรฐ รพaรฐ at Glรกmr lรก eigi kyrr. Varรฐ mรถnnum at รพvรญ mikiรฐ mein svo at margir fรฉllu รญ รณvit ef sรกu hann en sumir hรฉldu eigi vitinu. รegar eftir jรณlin รพรณttust menn sjรก hann heima รพar รก bรฆnum. Urรฐu menn รกkaflega hrรฆddir. Stukku รพรก margir menn รญ burt. รvรญ nรฆst tรณk Glรกmr at rรญรฐa hรบsum รก nรฆtr svo at lรก viรฐ brotum (32).
โA little time after men were aware that Glรกmr did not lay quiet. People become so greatly disturbed by this, that many fell into hysteria when they saw him, and some lost their wits. Even after Yule men thought they saw him at home on the farm. People became extremely scared. Many men then fled. Next, Glรกmr took to riding houses at night, so that he nearly broke them.โ

Grettir famously defeats Glรกmr, who is frequently associated with the Old Norse-Icelandic draugr, but not until the revenant has cursed Grettir with unceasing fear of the dark, as terrible light from Glรกmrโs eyes haunts Grettir until the end of his days and he becomes nyctophobic forevermore.
Another Yuletide monster discussed in the saga takes place when Grettir arrives at Sandhaug to investing a trวซllagangr โtroll-hauntingโ (chapter 64), and he encounters a trวซllkona โtroll womanโ (65). This monster enters the halls of Sandhaug on aรฐfangadag jรณla โYule-eveโ (64), and she plunders the halls during the long night:
Nรบ er frรก Gretti รพaรฐ at segja at รพรก er drรณ at miรฐri nรณtt heyrรฐi hann รบt dynr miklar. รvรญ nรฆst kom inn รญ stofuna trวซllkona mikil. Hรบn hafรฐi รญ hendi trog en annarri skรกlm heldr mikla. Hรบn litast um er hรบn kom inn ok sรก hvar Gestur lรก ok hljรณp at honum en hann upp รญ mรณti ok rรฉรฐust รก grimmlega ok sรณttust lengi รญ stofunni (65).
โNow it is said of Grettir that when it drew towards midnight, he heard a great din outside. Then a great troll woman came into the hall. She had a trough in one hand, and a blade, rather great, in the other. She looked around when she came in and saw where ‘Guest’ [i.e. Grettir] lay and ran towards him, but he jumped up to meet her, and they wrestled fiercely and struggled together for a long time in the hall.โ

Eventually, she drags Grettir from the hall, carries him off and tries to escape to her lair ofan til รกrinnar ok allt fram at gljรบfrum โup to the river and all the way to the gorgesโ (65). Grettir is ultimately able to cut her shoulder, slicing off the troll woman’s arm, a fatal blow which sends her off a cliff and to her death. After recovering from his encounter with the troll woman, Grettir sneaks into her cave and slays her companion, a jวซtunn โgiantโ (66).
The final Yuletide haunting discussed in this blog comes from Hrรณlfs saga kraka, when a massive flying dรฝr โbeastโ (probably a dragon of some kind) threatens the hall. The cowardly Hวซttr explains how this night-terror returns during Yule to haunt the hall of king Hrรณlfr:
Ok sem leiรฐ at jรณlum, gerรฐust menn รณkรกtir. Bวซรฐvarr spyrr Hวซtt, hverju รพetta sรฆtti. Hann segir honum, at dรฝr eitt hafi รพar komit tvรก vetr รญ samt, mikit ok รณgurligt, “ok hefir vรฆngi รก bakinu, ok flรฝgr รพat jafnan. Tvau haust hefir รพat nรบ hingat vitjat ok gert mikinn skaรฐa. ร รพat bรญta ekki vรกpn, en kappar konungs koma ekki heim, รพeir sem at eru einna mestir.
Bวซรฐvarr mรฆlti: “Ekki er hวซllin svรก vel skipuรฐ sem ek รฆtlaรฐi, ef eitt dรฝr skal hรฉr eyรฐa rรญki ok fรฉ konungsins.” Hวซttr sagรฐi: “รat er ekki dรฝr, heldr er รพat mesta trวซll” (chapter 35).
โAnd as Yule neared, men became gloomy. Bวซรฐvarr asked Hวซttr what caused this. He said to him that a beast had come there for two winters in a row, great and monstrous. โAnd it has wings on its back and frequently flies. For two autumns now it has visited and caused great harm. No weapon bites it, and the kingโs champions, those who are the greatest, do not come home.โโ
Bวซรฐvarr spoke: โthe hall is not so well guarded as I thought, if one beast shall here destroy the kingโs realm and livestock.โ Hวซttr said: โIt is not a beast, rather it is the greatest troll.โ”

This warning is quickly validated, for when jรณlaaptann โYule-eveโ arrives, King Hrรณlfr commands his warriors to stay inside and forbids them from fighting the monster, proclaiming that it is better to lose his livestock than his people. However, Bวซรฐvarr Bjarki sneaks into the night, dragging Hวซttr behind him, and the hero quickly slays the Yuletide monster terrorizing the kingdom. Then, at Bวซรฐvarrโs behest, Hวซttr consumes the flesh and blood of the beast, which strengthens and emboldens him, transforming him into a hero (in a way that recalls Sigurรฐrโs actions after Fรกfnir is slain).
These medieval stories of Yuletide monsters participate in a robust tradition of winter-time (and even Christmas-specific) hauntings, which continued throughout the ages and manifests still today. Dickensโ Christmas Carol is perhaps one of the more memorable, with visitations by four ghosts at the home of the miserly Ebenezer Scrooge on Christmas Eve. Dr. Seussโs Grinch renders its Scrooge-like antihero in the form of a green Christmas-hating monster bent on stealing Christmas, and Tim Burtonโs Nightmare Before Christmas explores the theme of Christmas haunting when the pumpkin king and leader of Halloween Town, Jack Skellington, decides he would rather celebrate Christmas one year instead out of sheer boredom with his own holiday. Jack then proceeds to haunt Christmas transforming cozy festivities into a horror show as if he were a Yule monster of old.

More recently, in George R.R. Martinโs Song of Ice and Fire (and HBO’s corresponding TV series Game of Thrones), winter monsters known as the White Walkers (seemingly inspired by Old Norse-Icelandic revenants), led by the fearsome Night King, come with the cold in the long night to terrorize Westeros. Even Netflixโs edgy reboot of Sabrina the Teen-age Witch, appropriately retitled Chilling Adventures of Sabrina (2018), gives a nod to medieval tales of wintertime monsters when during the solstice the Spellmans place a protective candle in the chimney to prevent Yule demons from entering their home; however, this does not stop Grรฝlaโan Icelandic giantessโfrom visiting during the night when the witches’ protective candle becomes accidentally extinguished.

Yuletide continues to provide a haunting wintry setting for monster visits. Although often balanced by saccharine images of Christmas as a source of light and warmth against the cold dark, what lurks beyond the illumination of society during the long night seems to readily elicit horror in the modernโas well as medievalโimagination.
