Werewolves in Pomerania

J. D. H. Temme

The belief in werewolves is common throughout all of Pomerania. One can
transform oneself into a werewolf by girding oneself with a strap that
has been cut from the back of a man who has been hanged. Werewolves are
especially fond of attacking horses. In the village
of Bork not far from Stargard for a long time a man made his entire
living by walking around the horse pasture in the village every night
and whispering mysterious words by which he protected the horses against
werewolves and other wolves, and this in spite of the fact that wolves
had long not been seen in that region.

(also other canines had straps).
