The witch bottle is a very old spell device. Its purpose is to draw in and trap harmful intentions directed at its owner. Folk magic contends that the witch bottle protects against evil spirits and magical attack, and counteracts spells cast by witches.
A traditional witch bottle is a small flask, about 3 inches high, created from blue or green glass. Larger and rounder witch bottles, up to 9 inches high, were known as Greybeards and employed so-called Bartmann or Bellarmine jugs. Bellarmines were named after a particularly fearsome Catholic Inquisitor, Robert Bellarmine, who persecuted Protestants and was instrumental in the burning of Giordano Bruno . Greybeards and Bellarmines were not made of glass, but of brown or gray stoneware that was glazed with salt and embossed with severe bearded faces designed to scare off evil.
A witch, cunning man or woman, would prepare the witch's bottle. Historically, the witch's bottle contained the victim's (the person who believed they had a spell put on them, for example) urine, hair or nail clippings, or red thread from sprite traps. In recent years, the witch's bottle has taken on a nicer tone, filled with rosemary, needles and pins, and red wine. Historically and currently, the bottle is then buried at the farthest corner of the property, beneath the house hearth, or placed in an inconspicuous spot in the house. It is believed that after being buried, the bottle captures evil which is impaled on the pins and needles, drowned by the wine, and sent away by the rosemary.
Sometimes seawater or earth are used instead. Other types of Witch-bottles may contain sand, stones, knotted threads, feathers, shells, herbs, flowers, salt, vinegar, oil, coins, or ashes. A similar magical deceive is the "lemon and pins" charm.
