A witch’s ladder is a string of 40 beads or a cord with 40 knots, used in Magic. The beads or knots enable a Witch to concentrate on repetitive chants or incantations without having to keep count. This enables the Witch to focus will and energy on the desired goal.
In lore, a witch’s ladder was a rope or cord of nine knots. It was believed that witches of old could cast a death spell over a person by tying the knots and then hiding the cord. Witch’s ladders are used in self-healing work.
