A common mistake
Many people believe today that the vikings were brutal and disgusting people with bad hygiene, which is in fact not true.
The name for saturday in Danish is Lørdag, where as dag means day and Lør is from the old norse word “Laur”, which means to wash or clean. That was the common day for the vikings to wash themselves, clothes and clean their houses etc.
This actually makes them one of the least dirty people at their time, where in some other cultures it was thought that you got sick of taking a bath once in a while.
