I recently found this face from a 16th-17th century German Bellarmine salt-glazed jug. Back then, people were very superstitious, and witches and their curses were greatly feared. To ward off a witch's spells, Bellarmine jugs were sometimes used as so-called 'witch bottles' and filled with urine, menstrual blood, bent rusty nails, pins, hair and finger nail clippings, thorns, broken glass, among other things. The witch bottles were either concealed beneath the fireplace hearth, buried under the floor or plastered inside the walls of a house to protect the occupants. Some bottles were thrown into a fire or smashed to cast off evil spirits. Thanks to @thecoventgardener for the video and mudlarking feature in the summer issue!
