According to common practices nowadays, their number is 13. They are the sons of the ogress Gryla and her subservient husband Leppaludi. Badly behaved children were threatened with the ugly Gryla, and were told, she would come and take them away and cook them for dinner.
This large family keeps quiet until Christmas approaches. Then the Yuletide lads start appearing, the first one 13 days before Christmas. Their behaviour is very unusual and they are all dressed in old-fashioned clothing or rags and their names originate in the old society of farmers and country folks. They do not wear the clean red and white attire of Santa Claus.
The first one to arrive in civilized areas is:
SHEEP COT DOLT, (STEKKJASTAUR, 12 December) who heads directly for the sheep cot to have fun with disturbing the sheep. The second one to arrive is
GULLY GAWK, (GILJAGAUR, 13 December) who rushes for the cowshed to try to get some milk. The third one to arrive is
STUMP, (STÚFUR, 14 December) who is extremely attracted to the contents of the kitchens, and does not miss a chance to
snatch something to eat. The forth one to arrive is
LADLE LICKER, (ÞVÖRUSLEIKIR, 15 December) who is very lean. He concentrates on finding pots with something well tasting and
licks the ladles. The fifth one to arrive is
POT CLEANER, (POTTASLEIKIR, 16 December) who consumes the burnt layers of food from the pots and leaves them shining clean.
The sixth one to arrive is
FOOD BOWL LICKER, (FALDAFEYKIR, 17 December) who always arrives late enough to get to the food rests left by the children and
finish the food from their bowls. The seventh one to arrive is
DOOR SLAMMER, (HURÐASKELLIR, 18 December) who hides in dark corners and waits for the opportunity to tease the people at the
farms and slams the doors during the night to wake everybody up. The eighth one to arrive is
SKYR GOBBLER, (SKYRGÁMUR, 19 December) who thinks of nothing but gourmet food and steals skyr from the larders, whenever he gets the opportunity. The ninth one to arrive is
SAUSAGE PICKER, (BJÚGNAKRÆKIR, 20 December) who raids the larders, because of his constant hunger, and prefers the well-tasting sausages. The tenth one to arrive is
PEEPING TOM, (GLUGGAGÆGIR, 21 December) who is extremely curious. He makes faces at the windows to scare the children, who run and hide, but the grown ups only laugh. The eleventh one to arrive is
DOOR SNIFFER, (GÁTTAÞEFUR, 22 December) who uses his sensitive nose to find all kinds of things, especially food, standing in doorways of houses. The twelfth one to arrive is
MEAT HOOK, (KJÖTKRÓKUR, 23 December) who likes smoked lamb very much, spares no effort to hook a leg of lamb from the stove through the chimney. The last one to arrive is
CANDLE BEGGAR, (KERTASNÍKIR, 24 December) who fancies candle lights and never gets enough candles for himself although he snatches quite a few from the children.
The Yule Cat is Gryla and Leppaludi house cat and it lives with them in their cave. On Christmas Night it eats those who didn’t get new clothes before Christmas.
Immediately after they have all gathered in the inhabited areas and entertained people, they start back to their parents one by one until the 6th of January, when the Icelanders celebrate with bonfires and fireworks the end of Christmas and the time of year, when the elves move house and travel about in their colourful attire on horseback. New year’s eve is also celebrated with much ado, large bonfires and hours of fireworks until the wee hours of the morning.
