Turst (Swiss)
Turst is a legendary folkloric figure from the agricultural communities of Lucerne, dating to the pre-Christian era. He is described as a "dreadful huntsman", of whom people should be wary in stormy weather. Turst blows his hunting horn through villages in the tempestuous months preceding Epiphany, accompanied by a baying pack of three-legged hunting dogs.
Turst's distinguishing features are his threat "step right; get out of my way" in which the careless pedestrian is turned into a member of the dog-pack if he should fail to get out of Turst's way in time. It is also said that barn doors should stay open at this time, enabling Türst to hunt through the barn unhindered.
