A witch ball is a hollow sphere of plain or staine glass hung in cottage windows in 18th century England to ward off evil spirits, witch's spells or ill fortune, though the Witch's Ball actually originated among cultures where witches were considered a blessing and these witches would usually "enchant" the balls to enhance their potency against evils.. Later, they were often posted on top of a vase or suspended by a cord (as from the mantelpiece or rafters) for a decorative effect. Witch balls appeared in America in the 19th century and are often found in gardens under the name "gazing ball". However, "gazing balls" contain no strands within their interior.
