Þorri (Jan-Feb)

Fourth month of winter

Þorri is the fourth month of winter. This is the height of winter in the northern hemisphere. And one of the toughest months in terms of harsh weather when Viking Age people would see their winter storages steadily depleted.

Who or what is Þorri?

Now, here’s a pickle. How to explain a debate with murky depths and confusing etymology?

First, let’s go basic. The Old Norse word thorri means ‘dry’. Some connect it to dry snow in linguistic analysis.1 Others see a connection to winter drought. Dry winters, for example, could lead to water problems later when summers turned warm.2 Or, even drought in terms of lack of food or resources.3

Then there are textual sources. The tale about Þorri is told in the thirteenth-century Fornaldarsögum Norðurlanda (part of the Flateyjarbók). Back in the days, there was Thorri, king of Finland and Kvenland. He was the grandson of a jötunn, and his son would be the founder of Norway. According to the Fornaldarsögum Norðurlanda the month is called Þorri because of this king who would make a sacrifice in the middle of each winter.4


Perhaps there was indeed such an ancient feast in midwinter, with rituals and sacrifice. It is called blót, the pagan worship of a deity.5 The tale clearly tells that king Thorri organized this blót, so he wasn’t the deity worshipped, by the way. Perhaps this idea confuses some about the feast’s history who have tried to link Þorri to the god Thor. Whilst I can imagine Thor being the happy recipient of any food and drink feast in his honour, the references to him remain (very) unclear and disputed.6 Therefore, I will happily stick to the sources we do know about.

The current Þorrablót has also little to do with the Viking Age and everything with the (Romantic) notions of a group of nineteenth-century Icelanders. Their early modern reinvention includes plenty of alcohol (a Brandywine with the cheerful name ‘Black Death’), sheep’s heads, ram’s testicles and cured shark… 7


Last but not least, the first day of Þorri is called Bóndadagur. Farmer’s or Husband’s Day. The man of the house has to go out in only his shirt and his pants on one leg – jump around the house and welcome Thorri!8
