A auggiasstal is a filthy place
Augias is a king of Greek mythology. Augias was a king with a large herd (3000 oxen), the stables of the flock were not fertilized in 30 years. Herakles was instructed to clean the couples in 1 day, this succeeded by having two rivers run through the stables that took all filthiness. This myth lives on in the Dutch expression: what is dirty here, it seems like a Augean stables.
