Grýla and the Yule Cat: The Christmas Monsters of Iceland

Most of Christendom spent the last two centuries sweetening its midwinter until nothing was left in the stocking but sugar. Iceland declined. Alone in the western world, the Icelanders carried into the age of fairy lights a Christmas still equipped with its full original apparatus of terror—a holiday with teeth—and its presiding figure is one of the most formidable ogresses in European tradition. Grýla lives in the mountains—in the Dimmuborgir lava fields, says the modern consensus—and at Yule she comes down. She is huge, ancient, and hideous, hoofed and horned in the old rhymes, with (the poems audit her anatomy variously) thirteen tails, three hundred heads or merely an enormous one, eyes in the back of her skull, and ears that hang to her shoulders and can hear children misbehaving across the whole of Iceland. Her sack is for the children themselves: the naughty, the disrespectful, the whiners—gathered farm by farm and carried home to the cave, where the old poems are perfectly explicit about the menu: her favorite dish is a stew of naughty children, and she has, say the verses, an insatiable appetite. Around her assemble the rest of the household: her third husband Leppalúði, lazy and cowed; her sons, the thirteen Yule Lads; and the family pet, which may be the most frightening thing in the entire northern Christmas—the Jólakötturinn, the Yule Cat: a black cat vast as a house that prowls the snow on Christmas Eve and eats, by the tradition's precise and startling statute, anyone who has not received at least one new piece of clothing before Christmas night.

The Ogress on the Doorstep

Grýla is old—far older than the Christmas she now works. Her name appears among the troll-wives in the thirteenth-century Edda lists; medieval verses already use her as a walking threat; and for centuries she was a year-round menace only loosely attached to midwinter, a begging ogress who came to doors demanding food or children. It was the later tradition that fixed her to Yule and gave her the office she holds today: the auditor of children's conduct, whose descent is scheduled and whose sack is filled strictly by desert. So seriously did the grown world take her that in 1746 the Danish authorities issued a decree formally forbidding parents to terrify their children with Grýla and her monsters—one of the few figures in folklore ever banned by name in legislation, which is, of course, the surest testimony to her power ever put on paper. The ban accomplished what such bans do: Grýla thrived, moderated her diet in the gentler tellings (a child who repents, all versions agree, slips out of the sack—her appetite has no power over the reformed), and consolidated her household into the pageant every Icelandic child now knows. Her thirteen sons, the Yule Lads—once child-stealing trolls themselves—dwindled into loveable pilferers who descend one per night through the thirteen nights before Christmas: Sausage-Swiper, Window-Peeper, Door-Slammer, Skyr-Gobbler, Candle-Stealer and their brothers, each named for his signature mischief, each now leaving small gifts in children's shoes on the windowsill—or, for the naughty, a raw potato: the entire moral machinery of the season miniaturized into footwear.

The Lads' own reform is documented with unusual precision. The oldest verses make them their mother's foragers—thirteen troll-sons descending to steal and snatch, each a personified household hazard of the dark weeks: the one who haunted the sheep-cotes, the one who skimmed the fresh milk, the one who scraped the pots, the one who lurked under beds after candles. The nineteenth century counted them, named them canonically in the beloved poem every Icelandic child recites, and the twentieth put them in red suits for the tourists—yet on their appointed nights they still arrive in strict rotation, oldest custom in the newest fleece, and the shoe on the windowsill is checked each morning with an anxiety no marketing invented. A tradition that can absorb Santa Claus without surrendering the raw potato has settled the question of who is absorbing whom.

The Cat That Audits the Wardrobe

But it is the Yule Cat that carries the tradition's strangest and deepest clause. The monstrous cat eats those—children or adults—who receive no new garment by Christmas Eve; whence the Icelandic phrase að fara í jólaköttinn, "to go to the Yule Cat," said of anyone left without new clothes for the feast. The rule looks arbitrary until one knows the economy under it, and then it looks like genius. In the old Icelandic countryside, the autumn wool work—the carding, spinning, knitting, weaving of the whole household through the darkening weeks—had to be finished before Yule; and the custom was that everyone who had done their share of the wool work received a new garment for Christmas from the master and mistress. The Yule Cat, as the folklorists read it, was the deadline made flesh: the members of a household who had worked were clothed and safe; the idle went unclothed into the feast—and the cat knew. Terror in the service of textile production: the threat prowled the farms each December on behalf of the year's most critical labor, and the new sock or shift on Christmas Eve was not consumer pleasure but a certificate of contribution, worn where the great auditor could see it. Iceland's poets never let the clause harden into mere management, though: the beloved twentieth-century verses that fixed the Cat for modern Iceland end by turning the statute into charity—perhaps, says the poem, you will remember to help the children who have nothing, so that they too wear something new to meet the Cat. The monster that ate the idle became the reason the poor were clothed. Few folk figures have ever been converted to mercy so precisely along the grain of their own terror.

The Esoteric Reading: The Audited Feast

Set Grýla's household beside the sweetened Christmas of the rest of the world and the esoteric meaning declares itself: Iceland preserved what the old midwinter always was—a feast with an examination attached. The Twelve (here thirteen) Nights are the year's thin place; through the gap come the powers; and the powers of the old Yule were never only givers: they were inspectors—of children's conduct, of household order, of the year's work—kin to the Alpine ladies who checked the spinning and the hearth, to the Slavic winter grandmother, and to the whole dark sisterhood of the season whose Russian matriarch keeps her own iron audit in the hut on hen's legs at the forest's edge, while her Alpine colleague, the chained companion of Saint Nicholas, works the same nights with birch and bell. The doctrine of the audited feast has three clauses, and the Icelandic household states them all. The darkness keeps accounts: what descends at the year's turning knows—Grýla's ears hear across the island—and the reckoning cannot be charmed, only reformed: the sole escape from the sack, in every version, is genuine repentance, the one currency the ogress cannot digest. The mischief is graduated: the thirteen Lads, descending one per night, are the tradition's ladder of small temptations and small gifts—the season as a nightly examination of shoes, each fault and each merit answered in kind, potato by potato; no single Judgment, but thirteen quizzes. And the feast must be earned into: the Yule Cat's wardrobe-statute is the deepest of all—one does not simply arrive at the feast of renewal; one arrives clothed in the year's work, wearing visible evidence of one's contribution to the common warmth, or one is eaten by the very night one failed to spin against. Every contemplative tradition has its Yule Cat under some name: the examination at the threshold of celebration, the question asked at the door of every festival of light—what did you make, this darkening year, to clothe someone against the cold? Iceland alone had the nerve to give the question fur and teeth.

Grýla stands today in effigy in Icelandic towns each December—enormous, sack over shoulder, cauldron at her feet—and the Yule Lads appear in schools and shopping streets on their appointed nights; Björk sang the Cat to the world; Dimmuborgir's tourist office receives the ogress's mail. The children, interviewed by folklorists and journalists alike, report the correct mixture in every generation: they love the Lads, respect the shoe, keep a wary eye on the ogress, and are not entirely sure about the Cat—which is exactly the theological posture their great-grandparents held on the same December nights, and precisely the one the whole tradition exists to teach. The rest of the world, meanwhile, having bred every tooth out of its midwinter, wonders annually why the feast feels weightless; Iceland could tell it. A light that costs nothing illuminates nothing. Keep the feast, by all means—but keep it as the old island kept it: shoes on the windowsill, wool work done, one new garment on every back in the house including the smallest and poorest; and out in the snow, magnificent and unretired, the black cat of the deadline, making its rounds, keeping the season honest.
