the same culture involves the piercing of the werewolf's hands with nails. Sometimes, less extreme methods were used. In the German lowland of Schleswig-Holstein, a werewolf could be cured if one were to simply address it three times by its Christian name, while one Danish belief holds that merely scolding a werewolf will cure it. Conversion to Christianity is also a common method of removing lycanthropy in the medieval period; a devotion to St. Hubert has also been cited as both cure for and protection from lycanthropes. Connection to revenants Before the end of the 19th century, the Greeks believed that the corpses of werewolves, if not destroyed, would return to life in the form of wolves or hyenas which prowled battlefields, drinking the blood of dying soldiers. In the same vein, in some rural areas of Germany, Poland and Northern France, it was once believed that people who died in mortal sin came back to life as blood-drinking wolves. These "undead" werewolves would return to their human corpse form at daylight. They were dealt with by decapitation with a spade and exorcism by the parish priest. The head would then be thrown into a stream, where the weight of its sins was thought to weigh it down. Sometimes, the same methods used to dispose of ordinary vampires would be used. The vampire was also linked to the werewolf in East European countries, particularly Bulgaria, Serbia and Slovenia. In Serbia, the werewolf and vampire are known collectively as vulkodlak. Hungary and Balkans In Hungarian folklore, the werewolves used to live specially in the region of Transdanubia, and it was thought that the ability to change into a wolf was obtained in the infant age, after the suffering of abuse by the parents or by a curse. At the age of seven the boy or the girl leaves the house, goes hunting by night and can change to a person or wolf whenever he wants. The curse can also be obtained when in the adulthood the person passed three times through an arch made of a Birch with the help of a wild rose's spine. The werewolves were known to exterminate all kind of farm animals, especially sheep. The transformation usually occurred during the winter solstice, Easter and a full moon. Later in the 17th and 18th century, the trials in Hungary not only were conducted against witches, but against werewolves
