Down to the middle of the last century there was a belief in vampirism in the east of Europe. This form of superstition created much anxiety in the public mind, none knowing when he might be bitten by one of those hated demons, and be thereby transformed into a vampire. Men of science bore testimony in favour of vampirism with seeming truthfulness and ability, worthy of a better subject. In England every man was supposed to have his "double" or "fetch." The appearance of a fetch created great uneasiness in the mind of the person witnessing the apparition. It was taken as foreboding death or serious calamity to the being represented. There were also churchyard ghosts in England, whose duty it was to watch bodies over which church rites had not been performed after violent death. In Scotland and England there were peculiar superstitious views concerning the souls of suicides. Authoritative decrees prohibited graveyard gates being opened to permit the bodies of such persons being carried through them for interment. If relations persisted in depositing the remains of a friend who had committed suicide, it was necessary for them to take the dead body over the graveyard wall after sunset. But in most cases the bodies of suicides and murderers were buried at a "cross road," with a stake driven through the corpse, to prevent its ghost rising to frighten or harm innocent people. The precaution of driving a stake through the body did not always prove effectual, if countless tales related of ghosts being seen in the vicinity of such unhallowed burying-grounds be true. Surprise need not be expressed at such superstition prevailing in a country where faith in witchcraft still lingers, and in which, at no very remote time, the statutes against witches were in full force. The State and the Church believed in the existence of demons and witches. Luther's opinions on the subject of the agency and operations of evil spirits may be inferred from his _Colloquia_. "Many devils," he says, "are in woods, in waters, in wildernesses, and in dark poolly places, ready to hurt and prejudice people; some are in the thick black clouds, which cause hail, lightnings, and thunderings, and which poison the air, the pastures, and grounds."
